摘　　要：塔什库梅尔地区是吉尔吉斯石油天然气股份公司(KNG)旗下油气区块之一,属于低勘探程度区,由于接续勘查投入不足,导致剩余可采石油资源有限。为了延长油田服务年限,寻找区块内接替油气资源,在系统分析区域地质资料的基础上,根据盆地演化阶段,对区块内沉积相特征以及构造形成和应力机制进行综合分析,总结出区块内油气圈闭类型及生、储、盖、移组合特征,并结合地震深度剖面解读,指出研究区可形成中下侏罗统—中侏罗统和古近系始新统—渐新统2套烃源岩,区内油气圈闭是以鼻状构造为主,在鼻状构造不同部位可进一步细分为褶皱型圈闭、褶皱—断裂型圈闭和褶皱—岩性型圈闭,并圈定了下一步工作重点及可能增储的区域。The Taskumel region is one of the oil and gas blocks under the Kyrgyz Oil and Gas Corporation(KNG),which belongs to the low exploration degree area,and the remaining recoverable oil resources are limited due to insufficient investment in subsequent exploration.In order to extend oilfield life and find replacement oil and gas resources in the block,based on systematic analysis of regional geological data,this study comprehensively analyzed sedimentary facies characteristics,structural formation and stress mechanism in the block according to the evolution stage of the basin,summarized the types of oil and gas traps in the block and the combination characteristics of generation,storage,cap and migration,and combined with seismic depth profile interpretation.It was pointed out that two sets of source rocks can be formed in the study area:Lower Jurassic-Middle Jurassic and Paleogene Eocene-Oligocene.The oil and gas traps in the study area were mainly nasal structure traps,which can be further subdivided into fold traps,fold-fault traps and fold-lithology traps at different parts of the nose structures.The next focus of work and potential areas for increased storage were delineated.
