摘　　要：在前人研究的基础上,以沉积学、天然气地质学、油气成藏地质学等理论作为依据,收录了研究区一百余口井的地质录井、测井资料以及物性分析、试气等资料,在对本溪组沉积特征、成岩作用、储层物性、微观孔隙结构等方面研究的基础上,分析并归纳了储层的控制因素。研究结果表明:本溪组气藏属于典型的岩性气藏,沉积特征与成岩作用控制的岩性差异是气藏富集的主控因素,对储层物性的好坏和气藏产能大小起到了决定性的作用;鼻状构造等因素对其油气的分布富集有一定的控制作用。Based on previous studies, according to sedimentology, geology of natural gas, hydrocarbon accumulation theory, through collecting data of 100 wells in study area including geological logging, logging and property analysis, gas testing and so on, controlling factors of the reservoir were analyzed and summarized based on the terms of Benxi group sedimentary characteristics, diagenesis, reservoir properties, microscopic pore structure studies. The results show that, Benxi gas reservoir is a typical lithologic gas reservoir; sedimentary characteristics and diagenesis are main factors of gas accumulation, playing a decisive role to the quality of reservoir properties and reservoir capacity; nose struc^tre and other factors have certain control effect on distribution of gas accumulation.
