摘要
塔里木盆地是一个既富油也富气的沉积盆地。目前探明率尚很低,勘探前景很大。孔雀河区块发育了寒武系、奥陶系、侏罗系等多套烃源岩,是油气勘探的基础。通过对烃源层发育状况、构造带所处位置、构造带内局部构造发育情况、构造形成期与油气运聚期匹配情况及已钻探井油气显示情况等研究分析,认为该区有2个有利的勘探目标:第一个是维马克-开屏鼻隆上的维马克2号背斜构造;第二个是龙口-英南断裂背斜带上的龙口5号背斜构造。
Tarim basin is a depositional basin with abundant oil and gas.Now,this basin is still in low degree of exploration and has great potentials for hydrocarbon prospecting.In Kongquehe area,multiple sets of source rocks developed in Cambrian,Ordovi-cian,Jurassic systems,etc.,being as foundations for its hydrocarbon prospecting.This paper presents the analyses of source rock development,structural belt location,local structural development in them,structure-formed periods versus petroleum migration/ac-cumulation,and oil-gas shows in drilled wells.It is suggested that there exist two favorable targets for petroleum prospecting:the first one is Weimark No.2anticlinal structure on Weimark-Kaiping nose uplift;the second one is Longkou No.5anticlinal struc-ture in Longkou-Yingnan faulted anticlinal belt.
