摘要/Abstract

摘要：

鄂西渝东地区从震旦系经古生界到中生界，经历了地台演化，盆地演化及褶皱、断裂演化3个阶段，大致形成基底逆冲及压性断块、张性断块和滑脱型逆冲褶皱组合等构造样式，其中发育了大量的构造圈闭、地层及复合圈闭等油气藏圈闭类型。这些油气藏圈闭类型的空间分布规律具有东西分带、南北分块的特点；而油气藏圈闭类型及空间分布规律的研究，对今后的油气勘探具有重要意义。

Abstract:

From the Sinian to the Mesozoic the tectonic evolution in the western part of Hubei and the eastern part of Chongqing experienced three periods, i.e. the platform, the basin and the fold with fault. In this evolutionary process, several types of the tectonic format, i.e. the basal thrusting, the squeezing block, the sheeting block and the detachment-type thrusting fold etc, had been formed. Ultimately, several types of the oil-gas pools including the tectonic type, the stratigraphic type and the composite type had been formed in these various tectonic formats. The spatial distribution of these oil-gas pools was characterized by the zoning in west-east direction as well as the partitioning in the south-north direction. The study on the spatial law of oil-gas pools was importantly meaningful for the future oil-gas exploration.

Key words: spatial distribution, entrapment type, the western part of Hubei and the eastern part of Chongqing
