摘　　要：首次应用单层厚度最大暗色泥岩对海拉尔盆地油气成藏进行研究,为断陷盆地油气勘探提供新的思路和方法。研究表明:单层厚度最大暗色泥岩层段中发育优质烃源岩,具有较高的生烃潜力,应用寻找单层最大厚度暗色泥岩的方法追踪优质烃源岩是一种简单而又有实际意义的一种方法;单层暗色泥岩的厚度与油气的聚集密切相关,单层厚度越大,单井的产能越高;单层暗色泥岩在断陷盆地中受沉积相带演化呈现明显的规律性,从陡坡带到缓坡带发育两个高值区,缓坡带单层暗色泥岩厚度高值区紧邻的砂体是油气主要富集带。The first application of the maximum thickness of monolayer of dark mudstone for hydrocarbon accumulation is studied in Hailaer basin,to provide new idea and method for oil and gas explorationin fault subsidence basin.The results show that： 1）The largest monolayer thickness of dark mudstone section develops high-quality hydrocarbon source rocks,with high hydrocarbon potential,and the application of the maximum thickness of monolayer dark mudstone to track high-quality source rocks is a simple and meaningful way.2）The single-layer thickness of dark mudstone and oil and gas accumulation are closely related,the greater layer thickness,the higher productivityof single well.3）The single dark mudstone in fault subsidence basin is related to evolution of sedimentary facies,and shows apparent regularity.It develops two high value areas from the steep slope to the gentle slope.The sand body which is adjacent to high value area of thickness of dark mudstone in gentle slope is oil and gas main enrichment zone.
