摘要:

塔里木盆地中央隆起带以发育多套烃源层系、多种储集类型、多类圈闭与油气藏、多期油气充注、多种成藏组合为基本特征,是典型的大型油气聚集带。基于当前钻井与地震勘探等资料以及地质综合研究,推论塔里木盆地中央隆起带油气新突破与新发现的主要领域是奥陶系礁滩相和加里东期古岩溶、志留系和泥盆系"不整合三角带"、寒武系盐下白云岩等。在加强重点勘探的同时,要进一步强化上述领域的针对性研究和做好勘探技术配套攻关,形成行之有效的综合勘探技术。

Abstract:

Central uplift belt in Tarim basin is a typical large petroleum accumulation zone characterized by multiple sets of source rocks,various types of reservoir rocks,many kinds of traps and oil/gas pools,multistage hydrocarbon charging,and various plays.According to the available drilling and seismic data and comprehensive geological research,it is believed that the Ordovician reef-bank facies,Caledonian palaeokarst,Silurian and Devonian "unconformity triangle zone",and Cambrian pre-salt dolomite are the potential targets of exploration in the central uplift belt of Tarim basin.While stressing on exploration in these key areas,researches shall be focused on the matching technologies for exploration,so as to develop effective and integrated exploration technologies.

Key words: large petroleum accumulation zone, central uplift belt, exploration success rate, exploration strategy, Tarim Basin
