【摘要】 塔西南从50年代至今曾经历了十分艰难曲折的勘探历程。塔西南属于前陆盆地性质,勘探工作主要集中在前陆冲断带部分。由于山前地震资料品质差,解释和构造建模困难以及勘探程度低和石油地质综合研究薄弱等是制约油气勘探停滞不前的重要因素。2000年在地震技术攻关的基础上,通过加强地质综合研究,优选勘探目标,在阿克莫木圈闭上的第一口区域探井——阿克1井在白垩系取得了天然气勘探的重大突破,从而证实了塔西南前陆冲断带具有形成大中型油气田的物质基础。通过资源潜力和储盖组合的分析,指出了下一步油气勘探的主攻方向。更多还原

【Abstract】 Southwest Tarim foreland basin, the strategic replacement area of CNPC and TOC (Tarim Oil Company), has the similar conditions of reservoir formation to the foreland basins in Middle Asian and Kuche foreland basin in Tarim basin. The exploration is so difficult that it has a long and tortuous course. The strategic breakthrough of the well Ake-1, is a great success after a series of measurements for the main explorative problems have been carried out, and also shows a wonderful exploration perspect.更多还原
