Abstract: According to present situation of exploration, the cause of formation of basins and age of production horizons, oil-bearing basins in China's continent can be divided into a longitudinal zone composed of the Yilan-Yitong-Bohaiwan-Jianghan group of basins and a latitudinal zone composed of the Junggar-Erlian-Songliao group of basins.These two zones contain 94% of the general output and 99% of the general reserves of China's petroleum, so we call them the longitudinal and latitudinal petroleum rich "golden zones".Based on evolution of China's plate tectonics, tectonic setting of basins, and conditions for oil-pool formation, this paper analyses the general and individual characteristics of the longitudinal and latitudinal petroleum-rich zones (contrasts them with two kinds three types oil-gas tectonic units) and concludes that the latitudinal zone has the most advantageous prospects for petroleum exploration.We therefore suggest that this latitudinal zone be considered the principal region for petroleum exploration in continental China within this zone, exploration should especially be strengthened in the Jungger basin, where may be discovered an especially huge oil field.

摘要： 从目前勘探现状、盆地成因、产层的主要时代等因素分析,中国大陆含油盆地可划为从依兰-伊通-渤海湾-江汉盆地群构成的经向带,和从准噶尔-二连-松辽盆地群组成的纬向带,二者共拥有中国石油总产量的94%和总储量的99%.因而我们分别称为经向和纬向石油富集“黄金带”.本文从中国板块构造演化、成盆构造背景和成藏条件等因素,分析了经、纬向石油富集带的共性和个性,并与国内二类三种含油气大地构造单元对比,认为纬向油气富集带具有最有利的石油勘探前景,建议列为“九五”期间中国大陆石油勘探的重点地区,其中应特别加强准噶尔盆地,沙漠区的勘探力度,可望找到特大型油田。
