摘要
和什托洛盖盆地前人研究工作主要集中在中东部地区,盆地西部基本为勘探空白区。通过在和什托洛盖盆地及周缘开展野外地质调查、样品采集、测试分析工作,整体评价了该区烃源岩特征和勘探潜力。研究表明和什托洛盖盆地发育泥盆系、石炭系和侏罗系3套潜在烃源岩,其中侏罗系为盆地烃源岩的主要发育层段,泥盆系及石炭系为烃源岩的次要发育层段。石油地质条件综合分析认为,和什托洛盖盆地具有一定的勘探潜力,白杨河凹陷、南部斜坡区是有利勘探区带,为下一步勘探方向提供了指导和依据。
Previous research work was mainly focused on central-eastern Heshituoluogai Basin,and there was almost no exploration work in the western part.Through the field geological survey,sample collection,test and analysis work,the source rocks characteristics and exploration potential of Heshituoluogai Basin were evaluated.The results show that three source rocks were developed in this basin,Devonian,Carboniferous and Jurassic.Jurassic is the main hydrocarbon source rock in the basin,followed by Devonian and Carboniferous source rocks.Comprehensive oil geological condition analysis shows that Heshituoluogai Basin has certain potential,and the Baiyanghe Sag and south slope are favorable exploration areas,which can provide some instructions and basis for next exporation.
