摘　　要：为了搭建断陷盆地等时地层格架，在综合分析海拉尔盆地地震、钻井和野外露头等资料基础上，从不整合面的成因出发，识别出构造和沉积2种类型不整合界面，划分出T02、T04、T22、T3、T4、T5等6个构造不整合面和T2、T21等2个沉积不整合面。海拉尔盆地不整合面的识别可使盆地内各凹陷之间所追踪的地震反射层位统一，从而确保在等时的地层格架中进行地层对比、沉积体系域和沉积相分析；同时，不整合面也是油气运移的重要通道，不整合面上、下的圈闭中已经发现了潜山、构造一地层和断块等多种类型油气藏。In order to establish the isochronic stratigraphic frame of the fault basin, on the bases of the synthetical analysis of the seismic, drilling and outcrop data of Hailar Basin, two types of the structural and sedimentary un- conformities are identified from the viewpoint of the genesis of the unconformities： six structural unconformities （ To2, To4, T22, T3, T4 and T5 ） and two sedimentary unconformities （ T2 and T21 ） . The distinction of the uncon- formities can make the unification of the tracked seismic reflection formations among the sags of the basin, thus the stratigraphic correlation, sedimentary system tract and facies analysis can be ensured in the stratigraphic frame; in the meantime, the unconformities are the important channels for the hydrocarbon migration, many kinds of petrole- um reservoirs such as buried hill, structural-stratigraphic and faulted-block ones are discovered in the traps of top and bottom of the unconformities.
