【摘要】：碎屑巖油氣儲(chǔ)層構(gòu)型是指不同級(jí)次儲(chǔ)層構(gòu)成單元的形態(tài)、規(guī)模、方向及其疊置關(guān)系。由Miall(1985)運(yùn)用于河流相儲(chǔ)層表征。碎屑巖油氣儲(chǔ)層構(gòu)型是儲(chǔ)層非均質(zhì)性的直觀表現(xiàn),直接影響到油氣藏開發(fā)效果,如何進(jìn)行精細(xì)構(gòu)型表征是關(guān)系到能否正確量化開發(fā)指標(biāo)、或者能否正確描述剩余油分布進(jìn)而有效減少低效井比例的關(guān)鍵因素。針對(duì)渤海明化鎮(zhèn)組河流相沉積儲(chǔ)層厚度低于地震分辨率的先天不足,對(duì)各種構(gòu)型在地震數(shù)據(jù)約束下可分辨尺度上進(jìn)行分類,形成3種構(gòu)型7類樣式的分類體系:垂疊型、側(cè)疊型和孤立型3種砂體構(gòu)型,垂疊型、密接觸側(cè)疊型、疏散接觸側(cè)疊型、離散接觸側(cè)疊型、下切侵蝕河道孤立型、決口扇孤立型、孤立河道7類樣式。研究了每類構(gòu)型的地震響應(yīng)特征,闡述了地震屬性描述圖版,概括了"地震構(gòu)型相"將構(gòu)型類型與地震響應(yīng)有機(jī)結(jié)合,構(gòu)建了基于地震構(gòu)型相的高精度概念模型表征方法。鑒于目前地質(zhì)建模和數(shù)模技術(shù)前提下無(wú)法對(duì)各類儲(chǔ)層構(gòu)型很好地網(wǎng)格化,建立"等效意義"的概念模型開啟了一種很好的技術(shù)途徑。
[Abstract]:The structure of clastic rock oil and gas reservoir refers to the form, scale, direction and superposition relation of different grade reservoir components. Miallan 1985) is used to characterize fluvial facies reservoir. The reservoir configuration of clastic rock is the direct manifestation of reservoir heterogeneity. It has a direct impact on the development effect of oil and gas reservoir. How to characterize the fine configuration is related to the correct quantification of the development index. Or can we describe the distribution of remaining oil correctly and effectively reduce the proportion of low-efficiency wells. In view of the inherent deficiency of fluvial facies sedimentary reservoir thickness lower than seismic resolution of Minghuazhen formation in Bohai Sea, Three types of structures are classified on discernible scales under the constraint of seismic data. They are vertical type, lateral type and isolated type, vertical type, dense contact side type, evacuation contact side type, vertical type and isolated type. In this paper, the seismic response characteristics of each type of structure are studied, and the seismic attribute description plate is described. The discrete contact side type, the down-cut erosion channel isolated type, the crevasse fan isolated type and the isolated channel type are studied. In this paper, the combination of structural type and seismic response is summarized. In this paper, a high precision conceptual model representation method based on seismic structural facies is constructed. In view of the present geological modeling and mathematical modeling technology, it is not possible to mesh all kinds of reservoir configurations well. Establishing a conceptual model of "equivalent meaning" opens up a good technical approach.
