[Abstract]:The right bank of amu river across the northeast of the Amu basin is the main source of gas pipeline in Central Asia and the main source of gas transmission from west to East. The middle upper Jurassic Calov Oxford carbonate rock reef reservoir is mainly developed under salt, and the natural gas is rich in natural gas resources. The right Bank of the Amu river has experienced the Calov stage carbonatite platform to Oxford phase carbon. The evolution of the acid salt rock platform is rich in sedimentary microfacies and various types of reservoirs. Different from the main exploration and development of the platform margin reef beach, the inter platform dolomite beach and the weathered crust karst reservoir, the main exploration and development objects on the right bank of the Amu River are concentrated in two phases in the platform and the platform margin slope, and the large reservoir in the platform and the platform margin is stored. The type and distribution law of the body are not clear, the prediction is difficult, and the exploration and development process is seriously restricted. The study of the sedimentary reservoir is of great significance to the high efficiency exploration and development of carbonate gas. This paper takes the middle upper Jurassic Calov Oxford order of the right bank of the Amu River as the research object, and takes the theory of sedimentology and sequence stratigraphy as the guidance, and it is filled with the theory of sedimentology and sequence stratigraphy. On the basis of the study of sequence stratigraphy and sedimentary microfacies, the development characteristics, genetic types, main controlling factors and geological models of the reservoir in the platform and the margin slope are studied on the basis of the data of outcrop, core, thin film, logging, logging, seismic and analysis, and so on. The main achievements are as follows: 1. the establishment of the LF Oxford stratum The sequence stratigraphic framework clarifies the relationship between the lithostratigraphy, the electrical strata and the sequence stratigraphic units, and forms the multiple stratigraphic series of different facies zones in the carbonate platform system. The predecessors divided the Western platform edge of the right bank of the right bank of the right bank of the right bank of the right bank of the right bank to 8 lithologic sections in the intra phase area of the Oxford, and divided 6 rocks in the platform margin slope and the basin facies area in the Middle East. The relationship between the rock stratum unit and the lithostratigraphic unit in different phases is not clear, which affects the understanding of the geological law. Through the study of the lithologic characteristics of outcrop and lithology, the lithostratigraphic unit of the outcrop is compared with the conventional well logging and imaging logging, and the characteristics of the interface of each rock section and the internal logging response are detailed. The fine stratigraphic correlation between the limestone and Oxford order units on the right bank of the Amu river is clarified. Through sequence stratigraphic analysis, the sequence stratigraphic interface of different levels is identified, and the order of the right bank of the Amu river is divided into two three order sequences. The single three level sequence is from the transgressive system domain, the early high system domain and the late stage. The system domain is composed of two quasi sequence groups and several quasi sequences within the system domain. Through the establishment of the regional sequence stratigraphic framework, the comparative relationship between the lithostratigraphy, the electrical stratigraphy and the sequence stratigraphic units is clarified, and the multiple stratigraphic series of different phases of the right bank carbonate platform system in the right bank of amu river is formed. In this way, the lithostratigraphic division and contrast scheme of more than 60 wells in the right bank is completed, which has been adopted and applied to the production by the oil field companies, thus solving the stratigraphic contrast problem in the lithologic sections of the carbonate rocks for a long period of time. On this basis, the system restored the slow slope type carbonate of the right bank of the right bank of the Amu river. The evolution process of the salt rock platform to Oxford edge carbonate platform reveals the geological foundation of the types of lithostratigraphic units and the difference of rock combination characteristics in different regions. It lays an important foundation for the study of sedimentary microfacies and reservoir in the platform margin slope facies area,.2. based on the analysis of sedimentary microfacies and logging facies in the core section and the establishment of sedimentary microfacies. The phase sequence evolution standard section has created a quantitative interpretation chart of high resolution graphic clustering logging facies for the sedimentary microfacies in the platform and the platform margin, realizing the continuous interpretation of the sedimentary microfacies in the whole well section, revealing the spatial distribution of the sedimentary microfacies in the platform and the platform margin. The sedimentary microfacies of the platform and the platform margin are rich in sedimentary microfacies and various types of rocks. Based on the core data to establish the sedimentary microfacies log recognition chart, it is helpful to realize the continuous interpretation of the sedimentary microfacies in the whole well section and the spatial distribution of the sedimentary microfacies in the platform and the platform edge slope. The sedimentary microfacies of the platform, the open platform, the edge of the platform, the edge slope of the platform and the basin facies are all kinds of sedimentary microfacies. Through the deep analysis of the continuous core data of the long well section, the standard profile of the facies sequence evolution of the sedimentary microfacies in the platform and the platform margin is established, and the logging response style of the sedimentary microfacies of the core section is established to form the different sedimentary microfacies in the platform and the platform margin slope. Conventional logging, clustering and logging facies and imaging logging mode have been used to create a quantitative interpretation chart of high resolution graphic clustering logging facies for the sedimentary microfacies of the platform and the platform margin, and to realize the continuous interpretation of the sedimentary microfacies of the whole well. The characteristics and quantitative evaluation of the sedimentary microfacies of the sedimentary microfacies of the platform margin slope.3. are carried out in the platform and the platform margin slope reef beach reservoir. The reservoir spatial and physical characteristics, the diagenesis type and the diagenesis stage are clearly defined, and the conventional logging and imaging logging quantitative interpretation templates are established, and the lower limit of carbonate reservoir and the fluid identification standard have been confirmed. The carbonate reservoir space in the limo slope of the right bank of the right bank of the Amu river is mainly in the secondary and intergranular pores, and the high energy grain beach in the platform keeps some primary holes, and the cracks in the slope area of the middle eastern part of the slope are developed. The study of diagenesis shows that compaction and cementation are the main types of destructive diagenesis, including sulfur. The buried dissolution and fracture effect of acid salt thermo chemical reduction (TSR) are the main constructive diagenesis. Through the analysis of Paleotemperature and paleosalinity, trace elements, carbon and oxygen isotopes and strontium isotopes of diagenetic fluids, the evolution stages of diagenesis are divided, and the model of diagenesis and pore evolution in the platform and the platform margin is established, and the reservoir is the reservoir. On the basis of zoning and stratified mineral model, the well logging interpretation mathematical model suitable for the carbonate rocks in the platform and the platform edge slope is selected, and the rational parameters are optimized by the log data statistics and the laboratory analysis data to form a conventional log interpretation template for the carbonate reservoir in the platform and the platform edge slope; On the basis of the identification of fracture types, the quantitative interpretation of the imaging logging seams has been carried out. Combining with the production data of the logging multi parameter rendezvous plate and the oil test conclusion, the lower limit of the conservative reservoir of the porosity of 4% of the carbonate rock in the platform and the platform margin is clearly defined. Gas and water SW < 50%, gas water same layer 50%sw70%, water layer: SW > 70%, for gas water interface identification, gas reservoir type research, reserves calculation, test oil layer section and the selection of development perforation section laid the foundation.4. division and platform margin slope carbonate reservoir type, set up different types of reservoir comprehensive identification chart, create with conventional logging data as variables The reservoir type quantitative discriminant model is used to analyze the main control factors of reservoir formation, to clarify the formation conditions and distribution rules of the large-scale reservoir, and to establish the distribution pattern of the reservoir type in the platform and the platform margin. The reservoir space and combination mode of the carbonate rock in the platform and the platform edge slope are varied, and the reservoir type and the complexity of the genesis are revealed, and the reservoir type is clearly defined. The pattern of plane and longitudinal distribution is of great significance for high efficiency exploration and development. Based on core, physical analysis and logging data, it is revealed that the carbonate rocks of the right bank in the right bank of the Amu River and the platform margin slope are developed in four types of reservoirs, such as pore type, pore type, fractured pore type and sewn hole type, and the comprehensive identification chart of various types of reservoirs is established. In this paper, the logging response values of various reservoirs are analyzed, and a quantitative identification model of reservoir type is established with the ratio of depth resistance ratio (RD/RS), the difference between the total porosity of density neutron and the porosity of acoustic porosity (t- s) as a multi variable reservoir type. The method of the quantitative reservoir type classification based on the conventional logging data has been formed, and the recognition of the distribution pattern of the reservoir type is not clear. The main control factors of various reservoir development show that the pore type and pore type reservoir are mainly controlled by sedimentary microfacies, sequence interface and related dissolution, and the fractured pore type reservoirs are mainly controlled by sedimentary microfacies, fractures and related dissolution, and the fractured and cavern reservoirs are mainly controlled by fractures and related buried dissolution. The formation conditions and distribution laws of the large reservoirs are clearly defined, and the distribution pattern of the reservoir type in the platform and the platform margin is set up by.5., which reveals that Saman Jay Per is a thick layer of stacked flat in the concealed paleo uplift, which breaks the traditional understanding of the main production layer of the gas field as the main barrier reef in the gas field and clear the scale. The depositional geological characteristics, control factors and distribution laws of the development of the flat beach have been established to guide the discovery of a number of large-scale flat shoals in the right bank of the right bank of the Amu river. The Sa Manjie Pere gas field found in the west of the right bank was considered to be a reef beach facies gas field on the edge of the platform. It is revealed that the formation of the lower Oxford formation in the SAM Jay gas field is a thick layer of thick layer beach in the upper layer of the concealed paleo uplift, breaking the geological understanding of the "platform levee reef" in the main gas field, and combining the paleogeomorphology with the sea level change analysis, and clearly defined the flat surface distribution, the breeding horizon, the type and combination of the beach body, and the scale of the platform. The development conditions of the inner beach reservoir have established the geological pattern of the development of the flat beach. The high site of the palaeogenic paleogenal area of the buried basement is large, vertical and multistage superposition, and a wide range of transverse distribution, forming a large-scale stacked flat. The single layer of the beach body in the low-lying parts of the paleogomorphology is thin, the total thickness is small, the scale of the flat beach is limited, sequence sequence is limited. Sequence sequence is limited. The inner platform inner beach reservoir in the stratigraphic framework is developed in the middle upper part of the Paran sequence. Based on the geological understanding of the control of the development of the flat beach in the palaeoggeomorphology, through the stratigraphic lamination technique, the compensatory thickness method and the residual thickness method, many sub grade paleogomorphic highlands developed in the Western Charles and kenzkkuru uplift have been identified. The development area of the inner beach is confirmed by drilling, which guides the discovery of several large-scale beach in the west of the right bank of the Amu river.
