【摘要】：論文以沉積(巖石)學(xué)、層序地層學(xué)、瓦斯與煤層氣地質(zhì)學(xué)等學(xué)科的理論和方法為指導(dǎo),通過(guò)對(duì)古交礦區(qū)GS-26、D13-4、GS-3鉆井巖芯的觀察和室內(nèi)試驗(yàn)研究、結(jié)合100余口鉆井及礦井瓦斯含量等相關(guān)資料的綜合研究,對(duì)研究區(qū)山西組沉積環(huán)境、層序地層學(xué)、巖相古地理及沉積環(huán)境與煤層氣富集的關(guān)系等方面進(jìn)行研究�；谙鄻�(biāo)志研究,認(rèn)為礦區(qū)山西組主要為三角洲沉積,包括三角洲平原、三角洲前緣2種沉積亞相以及8種沉積微相,并總結(jié)了其特征。將山西組分成3個(gè)三級(jí)層序、8個(gè)體系域,通過(guò)研究區(qū)鉆孔的層序?qū)Ρ?建立了全區(qū)層序地層格架。在層序地層格架內(nèi)探討了山西組沉積格局及演化特征,總結(jié)了山西組沉積模式。以研究區(qū)2#煤瓦斯含量為例,探討了沉積環(huán)境等因素與煤層氣的富集的關(guān)系。沉積環(huán)境對(duì)煤層氣富集影響,主要體現(xiàn)在煤層厚度、頂?shù)装迥鄮r厚度以及煤質(zhì)等方面,同時(shí),探討了構(gòu)造演化、褶曲發(fā)育部位、斷層的發(fā)育特征、煤層埋深以及水文地質(zhì)條件對(duì)煤層氣富集的影響。
[Abstract]:Guided by the theories and methods of sedimentary (lithology), sequence stratigraphy, gas and coalbed methane geology, the paper studies the core of GS-26D13-4 GS-3 drilling in Gujiao mining area. Combined with the comprehensive study of more than 100 drilling wells and mine gas content, the sedimentary environment, sequence stratigraphy, lithofacies paleogeography and the relationship between sedimentary environment and coalbed methane enrichment of Shanxi formation in the study area are studied. Based on the study of facies markers, it is considered that the Shanxi formation in the mining area is mainly delta sedimentary, including delta plain, delta front two sedimentary subfacies and 8 sedimentary microfacies, and its characteristics are summarized. Shanxi formation is divided into three third-order sequences and eight system tracts. The sequence stratigraphic framework of the whole area is established by the sequence correlation of boreholes in the study area. The sedimentary pattern and evolution characteristics of Shanxi formation are discussed in sequence stratigraphic framework, and the sedimentary model of Shanxi formation is summarized. Taking coal gas content in study area as an example, the relationship between sedimentary environment and coalbed methane enrichment is discussed. The influence of sedimentary environment on coalbed methane enrichment is mainly reflected in coal seam thickness, top and floor mudstone thickness and coal quality. At the same time, the structural evolution, fold development location and fault development characteristics are discussed. The influence of coal seam depth and hydrogeological conditions on coalbed methane enrichment.
