摘要

摘要: 库车褶皱冲断带天然气成藏体系由侏罗系煤系烃源岩、侧断坡断层输导体系和侧断坡相关背斜构造圈闭构成.相对于走滑断层而言, 侧断坡断层是有效的天然气运移优势通道.研究表明, 侏罗系煤系生成的天然气通过侧断坡断层向上运移到白垩系巴什基奇克组侧断坡相关背斜的砂岩储集层聚集成藏, 异常压力的幕式泄压可能是油气运移的主要方式.克拉2、迪那2、迪那1和吐孜1等气田的发现是库车褶皱冲断带天然气成藏体系的有效体现.侧断坡相关背斜是库车褶皱冲断带天然气勘探的新领域.

Abstract: Petroleum accumulation system in the Kuqa fold-thrust belts consists of Jurassic coal source rocks, fault migration system and lateral ramp-related anticline traps. The lateral ramp fault is taken as an effective pathway of hydrocarbon migration in the strike-slip fault. The results indicate that hydrocarbon generated from the Jurassic coal migrates through lateral ramp fault upwards into the Cretaceous Bashenjiqike sandstone traps in the lateral ramp-related anticlines. Hydrocarbon migration may be associated with episodic expulsion of overpressure. The discovery of the Kela-2, Dina-2, Dina-1 and Tuzi-1 gas fields supports above hypoth- esis. Hence, the lateral ramp-related anticline may be a new potential realm for hydrocarbon exploration in the Kuqa fold-thrust belts, Tarim basin.
