摘要
吐哈盆地托克逊凹陷前期油气勘探开发主要集中在伊拉湖构造带,根据邻近凹陷实际勘探经验及托克逊凹陷目前钻井资料,以现代油气地质理论为指导,通过全面解剖伊拉湖构造带三叠系已知层系油藏,系统分析了托克逊凹陷的烃源岩、储集层、盖层及圈闭等油气系统形成的基本要素。研究表明,托克逊凹陷勘探前景广阔,存在多个有利的油气勘探领域。下一步应在区域扩展后期保存好的三叠系构造圈闭油气藏的同时,积极探索托克逊凹陷侏罗系水西沟群自生自储的致密砂岩气藏及三叠系小泉沟群、二叠系桃东沟群地层-岩性油气藏。
The early oil&gas exploration and development in Toksum depression of Turpan-Hami Basin mainly focused on the Yilahu structural belt.In this paper,the primary factors,including hydrocarbon rocks,reservoirs,caps and traps for hydrocarbon system formation are analyzed based on the experiences and drilling data in neighboring areas.It shows that there are geological conditions for reservoir in Toksum depression,and several favorable areas for prospect.In the next stage,Triassic structure trap reservoirs that later preserve well should be expanded,at the same time,self-generating and self-preserving tight sand gas accumulation reservoirs of the shuixigou group,stratigraphic-lithologic reservoirs of xiaoquangou group and taodonggou group in Toksum depression should be explored actively.
