摘要：

油气储量是油气勘探的重要成果之一。油气储量的增长、变化和分布规律是对一个盆地勘探历程和未来油气勘探潜力的综合反映。塔里木盆地的油气勘探自20世纪80年代中期开始进入一个新的发展阶段,油气储量持续不断地增长。截止到2001年底,塔里木盆地累计探明石油地质储量5.38×108t,天然气地质储量6131.95×108m3。石油与天然气资源探明程度分别为4.65%及5.39%,探明程度较低,依然具有较大的油气勘探潜力。塔里木盆地已发现的油气田,以中型油田和大型气田为主,油田的储量丰度为低-中丰度,气田的储量丰度以中-高丰度为主。塔里木盆地已获油气地质储量在构造单元和层位上呈明显的不均一性。已发现的石油地质储量主要分布在沙雅隆起和卡塔克隆起,分布层位主要为奥陶系、石炭系、三叠系和第三系;已获天然气储量主要分布在库车凹陷,分布层位主要为白垩系和第三系。

Abstract:

Oil/gas reserves is one of the important achievements got in petroleum exploration. Growth, change and distribution pattern of reserves comprehensively reflect the exploration history and future exploration potential of a basin. Exploration in Tarim basin has entered into a new development stage since the middle of 1980's,and oil and gas reserves have been increasing continuously.By the end of 2001,cumulative proved oil and gas reserves in place had reached 538 million tons and 613.195 billion m8,respectively,in Tarim basin.Exploration degree of both oil and gas are low (4.65% and 5.39%,respectively),indicating that there are still large petroleum exploration potentials.The discoveries in Tarim basin are mainly of medium oilfields and large gas fields,and the abundance of oilfields ranges from low to medium,while that of the gasfields ranges from medium to high.Distribution of reserves that have already been discovered is significantly uneven in various structural units and horizons.The proved oil reserves in place are mainly distributed in the Ordovician,Carboniferous,Triassic and Tertiary in Shaya and Katake uplifts,while the proved gas reserves in place are mainly distributed in the Cretaceous and Tertiary in Kuqa depression.

Key words: oil and gas reserves, distribution characteristics, reserves scale, abundance of reserves
