摘　　要：塔里木盆地孔雀河地区发育有寒武系—奥陶系和侏罗系2套优质烃源岩,具备了油气勘探的基础。分析了该区地层及沉积相特征和烃源岩、储集层、盖层发育特征以及构造带所处位置、构造带内局部构造发育和构造形成期及其与油气运聚期匹配情况,还分析了在该区已钻井的油气显示情况。认为该区有2个有利的勘探目标,即龙口背斜构造带和维马克—开屏背斜构造带。Kongquehe area of Tarim basin is a favorable exploration area.In Kongquehe area, two sets of multiple source rocks developed in Cambrian-Ordovician, Jurassic, being as foundations for its hydrocarbon prospecting. This paper presents the analyses of stratum and sedimentary facies,source rock, reservoir,seal rock development, structural belt location, local structural development in them, structure-formed periods versus petroleum migration/accmulation, and oil-gas shows in drilled wells. It is suggested that there exist two favorable targets for petroleum prospecting: Longkou anticlinal structure belt and Weimake anticlinal structure belt.
