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。
For the first time, the study on hydrocarbon accumulation in the Hailaer Basin is carried out for the first time by using the largest dark mudstone of single layer thickness, providing new ideas and methods for oil and gas exploration in fault-depression basins. The results show that the development of high quality source rocks in the monolayer maximum dark mudstone section has high potential for hydrocarbon generation. It is a simple and practical way to search for high quality source rocks by looking for the monolayer maximum thickness dark mudstone The thickness of monolayer dark mudstone is closely related to the accumulation of oil and gas. The greater the single layer thickness, the higher the productivity of single well. The evolution of monolayer dark mudstone in sedimentary facies shows obvious regularity , And two high value zones are developed from steep slope zone to gentle slope zone. The sand body adjacent to the high value zone of single-layer dark mudstone of gentle slope belt is the main oil-gas enrichment zone.
