摘要： 总结了塔中地区的勘探成果,讨论了塔中北坡构造带及中央断垒带的资源潜力,分析了钻探失利的五个原因,其中由静校正和平均速度场问题导致的构造不落实是钻探失利的主因。指出塔中地区油气勘探重点应放在下构造层塔中I号断裂带和中构造层北坡低幅度构造带上,侧重石炭系东河砂岩低幅度背斜圈闭和奥陶系内幕地层-岩性圈闭等圈闭类型的评价,提高预测碳酸盐岩有效储集层的能力,重视火成岩对油气成藏的影响和奥陶系“丘状异常体”的发育特征,开拓勘探新领域。

Abstract: This paper outlined the exploratory achievements in central Tarim area, discussed its resource potentials in north slope structural belt and central fault horst zone,analyzed five causes for failure of drilling, in which the major cause is indeterminate structures for drilling resulted from static corrections and average velocity field problems. It is pointed out that the exploration of central Tarim area should focus on No.1 fault belt in lower structural layer and that of low amplitude in middle structural layer. In addition, evaluation in trap types of low amplitude anticlinal trap in Donghe sandlayer of Carbonifeous and stratigraphic-lithologic trap of Ordovician should be paid attention to,improving ability of prediction of effective carbonate reservoir; in light of effect of igneous rock on hydrocarbon reservoir and developed characteristics of Ordovician “domal abnormal body” search for new domains for petroleum exploration.

Key words: Tarim basin, exploratory achievement, resource, structure, Carboniferous, Ordovician, carbonate
