摘　　要：八面河地区位于凹陷边缘,不整合油藏发育,及时研究总结不整合油藏分布规律对于指导油气发现有重要意义。通过研究总结不整合面类型与不整合圈闭的分布规律,应用剥蚀余量外推法、夹角等厚外推法和地层切片法综合确定主要层组的地层尖灭线,并结合区域地质情况总结了不整合油藏分布规律,指出有利区,对八面河地区和相似区域的勘探增储具有重要的现实意义。Bamianhe area is located at the margin of the depression,and unconformity oil reservoirs are developed.It is of great significance to study and summarize the distribution regularity of unconformity oil reservoirs for directing oil and gas discovery in a timely manner.The formation pinchout lines of the main layer groups are determined comprehensively by studying the type of unconformity surfaces and the distribution regularity of unconformity traps,and also by applying denudation margin extrapolation,angle isopachous extrapolation and strata slicing,and the unconformity reservoir distribution regularity is summarized in combination with the regional geology to identify the favorable zone,which has important practical significance for the Bamianhe area and the like.
