巴楚-麦盖提的区域构造演化与油气分布规律

巴楚-麦盖提地区位于塔里木盆地的中西部,跨越巴楚断隆和麦盖提斜坡两个二级构造单元.通过研究区域构造演化,以主力烃源岩(C-O1)的主生油期为出发点,追踪油气的生成、运移、聚集,保存及调整破坏的动态成藏过程,从而探索油气分布的有利区带.分别楚立了西部隆起,东部斜坡和麦盖提斜坡的成藏模式,讨论分析了构造对三者油气分布的控制,提出了油气勘探的重点.

Regional tectonic evolution and distribution of Bachu-Markit

Bachu arch-Markit slope is located in the central-western Tarim Basin and covers two II-grade tectonic units. At the present time, there are some dozens of wells which have not given out commercial oil and gas flow except Bashituo and Hetianhe oil and gas reservoirs. This paper studies the tectonic evolution of this area, starting with the main hydrocarbon source and its main stage of oil generation, traced (hydrocarbon) generation, migration, accumulation, adjustment and destruction and probed into favorable zones of oil/gas distribution. Accumulation models of western upheaval, eastern slope and Markit slope are established. This paper also proposes that the distribution of hydrocarbon is controlled by the tectonic movement. Finally, it points out hydrocarbon exploration key points.
