摘要：

鄂尔多斯盆地是中国第二大沉积盆地,油气资源丰富,勘探前景广阔。其中,三叠系延长组发育典型的低渗透—致密油藏,勘探难度大。50年来,持续深化鄂尔多斯盆地中生界油藏地质研究,提出了侏罗系油藏群成藏理论、内陆坳陷湖盆大型岩性油藏成藏理论和陆相页岩油成藏理论,实现3次战略转移,发现4个储量超过10×10⁸ t的常规油气区和1个储量达20×10⁸ t的页岩油接替区,探明石油储量连续10 年年均增长超3×10⁸ t,成为中国增储上产速度最快的油区,原油年产量占中国的12.5%,可供其他同类型盆地的油气勘探借鉴。

Abstract:

The Ordos basin is the second largest sedimentary basin in China with abundant oil and gas resources and broad exploration prospects. Typical low-permeability-tight oil reservoirs are develpoed in the Triassic Yanchang formation in the basin,which are difficult to explore. Through continously geological researches on the Mesozoic oil reservoirs in the Ordos basin over the past 50 years,some theories about hydrocarbon accumulation in Jurassic reservoir groups,in large-scale lithologic reservoirs in inland depression lake basins and in continental shales have been formed. By virtue of three strategic shifts,four conventional hydrocarbon provinces with reserves exceeding 10×10⁸ t and a successive zone with shale oil reserves of 20×10⁸ t have been discovered. The proven oil reserves have increased by an average of over 3×10⁸ t per year for 10 consecutive years. Thus,Changqing oilfield in Ordos basin has become an oil and gas province with the fastest increase in reserves and production in China and contributed 12.5% of China's annual oil production,which provides a reference for the petroleum exploration in other similar basins.

Key words: Ordos basin, Mesozoic, Triassic, Jurassic, lake basin, exploration enlightenment, exploration prospect
