中国大陆纬向石油富集带地质特征

从中国板块构造、盆地成因、产层主要时代等因素分析,中国大陆含油盆地可分为经向的伊兰一伊通一渤海湾一江汉等盆地带和纬向的准噶尔一二连一松辽等盆地带,两带共拥有中国石油产量和储量的绝对优势,因而分别被称为经向和纬向石油富集“黄金带”.在分析了渤海湾盆地与松辽盆地分属于经向和纬向石油富集带后,着重讨论了纬向石油富集带的特征,并与国内两类三种含油气构造单元对比,认为西北地区处于中国大陆今后石油发展战略重要位置,并有可能在准噶尔盆地腹地找到特大型油气田.

GEOLOGIC CHARACTERISTICS OF LATITUDINAL HYDROCARBON ABUNDANCE ZONES IN CHINA CONTINENT.XJPG,

By analysis of the plate tectonics, basinal origin and geologic ages of major reservoirs, petroliferous basins in China continent can be classified as longitudinal basin zone represented by Yi-lan - Yitong - Bohai Bay - Jianghan basins and latitudinal basin zone by Junggar - Erlian - Songliao basins. The two zones are entitled to be called "Golden Zone"respectively for their having a great advantage in China' s crude reserves and output. This paper is devoted to features of the latitudinal oil -rich zone by research of Bohai Bay basin and Songliao basin that belong separately to the longitudinal and latitudinal zones, followed by making a correlation between the zones and petroliferous structural units of two types or three sorts. It is concluded that northwest China will be in a dominant position of China continent petroleum development strategies in the future, and it is possible to disclose giant oil/ gas fields in hinterland of Junggar basin.
