鄂尔多斯盆地是我国第二大沉积盆地,油气资源十分丰富,但勘探开发对象是典型的“低渗、低压、低产”油气藏。由于储层物性差、油气藏隐蔽性强及复杂的黄土、沙漠地表条件等客观因素的限制,勘探开发难度愈来愈大。近年来,长庆油田成功实现了0. 5 ×10 - 3μm2 以上的低渗透油气田勘探开发技术的突破,形成了高分辨率地震预测、隐蔽性油气藏综合勘探、井网优化、超前注水等低渗透油气田勘探开发配套技术系列。

Ordos Basin is the second largest sedimentary basin in China with very rich oil and gas resources.However, the exploration targets are typical reservoir s of low permeability, low pressure and low output .The exploration and development become more and more difficult due to the restriction of objective factor s such as poor reservoir properties, strong subtle characteristics and complicated surface covered with loess and desert. Based on the objective reality of the exploration and development, through independent innovation, Changqing Oilfield Company successfully implemented technological breakthroughs of more than 0.5×10 ^{- 3}μm² low permeability oil-gas field exploration and development, and developed a series of techniques for low permeability field exploration and development in the aspect s of high-resolution seismic exploration, subtle reservoir integrated exploration, well pattern optimization, advanced water injection. Recently, the effective development technologies for 0.3 ×10 ^{- 3}μm² ultra-low permeability eservoir and Sulige Gas Field have a great breakthrough, which promote domestic and foreign development to the low permeability reservoir, and enhance the growth of oil and gas resources.
