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。
Based on the current exploration status, the origin of the basin and the main epoch of the pay zone, the oil-bearing basins in China can be classified as meridional belts formed from the Yilan-Yitong-Bohai Bay-Jianghan basins and from the Junggar- Erlian- Zonal belt formed by the Songliao basin group, both with a total of 94% of China’s total oil production and total reserves of 99%. Thus we are respectively referred to as “gold band” enrichment by meridional and latitudinal oil. Based on the tectonic evolution, basin tectonic setting and reservoir forming conditions in China, the paper analyzes the commonness and individuality of petroleum enrichment belts in the latitudinal and zonal direction. Compared with the tectonic units of three types of petroleum-rich terrestrial units in China, The oil-gas-rich belt has the most favorable prospects for oil exploration. Suggestions are listed as key areas for petroleum exploration in mainland China during the Ninth Five-year Plan period. In particular, exploration efforts in the Junggar Basin and desert areas should be intensified to find extra-large oil fields.
