【摘要】 为提高塔里木盆地油气勘探预测水平,首要的是扣强油气层评价工作。从已有资料分析,石灰二叠系及三叠侏罗系等的一部分组段,其生油气能力是不应怀疑的,对海相碳酸盐岩的生油潜力应作深入研究后,再作出令人信服的判断。对干酪根演化史的恢复建议使用演化指数法为好。 对大部分地区而言要考虑多重油气源混合聚集的可能,在钻探过程中就不会偏爱某个唯一目的层,而忽视钻遇的其他储层。 进行古应力场的研究,有助于分析圈闭的形成机制和分布规律,以及正确解释其他一些构造现象;再配合进行地表化探工作,将有利钻探圈闭的选择。更多还原

【Abstract】 In order to increase predication level for hydrocarbon exploration in Tarim Basin, it is very important to evaluate the hydrocarbonbearing formations. From the analysis of availible materials, it is undoubted that some groups of the Carboniferous, Permain, Triassic and Jurassic System could generate hydrocarbon. But the convincing judgement on the potentiality of the marine carbonate rock should be obtained after further study. Thermalalteration index is a better way which was suggested that the recovering evolution history of kerogen.In most areas, it is neccessary to consider the possibility of mixture accumulation of polysource hydrocarbon, then we could avoid prefering some bed of interest to else drilled reservoirs during drillhole exploration.The study of paleostress fields is helpful to the analysis of formation mechanism and distribution regularity of traps and to the correct interpretation of other structure appearances; which adds to surface chemical exploration would be good to choosing the traps provided for drillhole exploration.更多还原
