摘要
摘要:推覆构造是一种和油气有关的重要构造形式，主要产出于造山带前陆，是挤压或压缩作用的结果，对油气的生成、储集、运移、圈闭和保存条件都有着重要的影响.研究区从漠河盆地、海拉尔盆地到二连盆地内的中生代推覆构造，组构了大兴安岭西盆地群推覆构造.本文通过对三个盆地五种推覆构造的地震学研究，将其推覆方向归结为两类：第一类由北西向南东推覆，在三个盆地中表现明显；第二类由南东向北西推覆，在海拉尔盆地和二连盆地内有显示.认为第一类推覆作用来源于蒙古-鄂霍茨克洋自西向东的闭合；第二类推覆作用来源于太平洋板块俯冲的远程应力作用.

Abstract:Nappe is an important oil and gas structure, mainly located in forelands of orogenic belts. It is caused by extrusion or compression and plays an important role in generation, storage, migration, trap and preservation of oil and gas.This study focuses on such structure of Mesozoic in the Mohe, Hailaer and Erlian basins west basins of the Da Hinggan Mountains. Based on seismic data from five types of the nappe structure, their motion directions are classified into two categories. The first is from Northwest to Southeast (NS) which is obvious in all the three basins; The second is from Southeast to Northwest (SN) which can be found in the Hailaer and Erlian basins.It is suggested that the first category of nappes is produced by the closure of the Mongolia-Okhotsk Ocean from the west to the east, while the second can be attributed to the long-distance stress induced by the subduction of the Pacific plate in the east.
