摘　　要：在琼库恰克构造带的形成和发展过程中经历了海西运动期古构造形成阶段及喜马拉雅运动期现今构造定型阶段。在分析构造发育史的基础上,进行了古构造对储集层、对油气成藏、对油气分布的控制作用的研究,认为现今的琼库恰克油气藏实际是一个古构造油气藏,利用储集层横向预测和烃类检测技术,对有利储集层及油气分布范围进行了预测,认为群5井以西地区仍存在着巨大未探明的储量,是非常有利的勘探区域。The formation and development of Qongkuqak structural zone underwent two stages,i.e.,Hercynian paleostructural forming stage and Himalayan present-structural forming stage.Based on analysis of structural development history in this structural zone,control of pale ostructure on reservoir,control of paleotectonic movement on hydrocarbon accumulation and then hydrocarbon distribution are studied.It is believed that present oil-gas pool is actually Qongkuqak paleostructual reservoir.West area of Well Q-5has still huge unproved reserves and is very favorable area for petroleum exploration.Also,this paper offers prediction of the favorable reservoir and hydrocarbon distribution extent by applying reservoir lateral prediction and hydrocarbons detection techniques.
