中文摘要:
      目前页岩含气性控制因素是页岩气勘探研究的一个关键问题。基于中牟区块及周边研究资料,在太原组—山西组海陆过渡相的泥炭沼泽亚相和潟湖亚相沉积岩是页岩气发育最有利相带,对岩芯进行含气量测试研究。结果表明:1)山西组泥页岩平均含气量为1.82 m3/t,累计厚度20~25 m;太原组泥页岩平均含气量为2.64 m3/t,累计厚度26~30 m。2)太原组泥岩的有机碳含量要高于山西组;随着埋藏深度的加大,有机碳含量具有逐渐增加的趋势,且非均质性较强。3)地层垂向岩性变化、厚度、有机质含量、有机质生烃能力影响页岩含气性。4)现场解吸气量、有机质丰度、厚度、埋深、裂缝、孔隙结构是牟页1井山西组—太原组页岩含气性控制因素。
英文摘要:
      At present, the controlling factors of shale gas content are a key issue in shale gas exploration and study. According to the data of Zhongmou block and nearby regions sedimentary rock of peat swamp sub-facies and laggo0n sub-facies of the sea-continent transitional facies in Taiyuan Formation-Shanxi Formation is the most favorable facies belt of shale gas. The gas content of the rock core was tested and studied. The result shows that the average gas content of the argillutite (cumulative thickness (20 to 25 m), in Shanxi Formation was 1.82 m3 and the average gas content of argillutite (thickness 26 to 30 m) in Taiyuan Formation was 2.64 m3/t; the organic carbon content of argillutite in Taiyuan Formation was higher than that in Shanxi Formation and the organic carbon content gradually increases with stronger heterogeneity to depth; vertical lithologic variation, thickness, organic matter content and ability of the organic matter to generate hydrocarbon affect the shale gas content and the on-site desorption gas amount, organic matter abundance, thickness, burial depth, fracture, pore structure are the main control factors.
