摘　　要：在对渤海湾盆地惠民凹陷南部馆陶组底部不整合的地质录井、测井资料识别分析基础上,将不整合剖面岩性结构划分为7种类型。编制了研究区不整合剖面岩性结构类型平面分布图,分析了其在平面和剖面上的变化特点。综合分析认为研究区馆陶组底部不整合具有形成圈闭的有利条件,但不具备油气在区内进行较长距离运移的有利条件。Based on the analysis of geological log data and well logging data of basal unconformity in Guantao Formation of southern Huimin Sag, Bohaiwan Basin, lithology structure of unconformity profile is divided into seven types. Plane distribution map of lithology structure type of unconformity profile is drawn up in the study area and the change characteristics of the plane and the profile are analyzed. It is believed that the basal unconformity of Grantao Formition presents the favourable condition of trap formation, but it has not the favourable condition of hydrocarbon migration within the area of long distance.
