摘　　要：陕西延长石油(集团)有限责任公司(以下简称延长石油集团)在鄂尔多斯盆地大力推动石油、天然气、页岩气勘探开发理论研究和技术攻关,多类型资源协同发展,取得显著效果。石油勘探方面,提出了延长组下组合特低渗"交替式"石油成藏理论认识,综合利用量化运聚模拟等技术,实现下组合勘探突破,探明石油地质储量2.75×10~8t。石油开发方面,揭示了裂缝性特低渗油藏渗吸—驱替双重作用机制,创建了"适度温和"注水开发技术,油田自然递减率由18.22%下降到12.6%,实现了低品位油田的有效开发。天然气勘探开发方面,提出鄂尔多斯盆地东南部上古生界"浅水环境岸线频繁迁移控砂"和"成熟烃源灶迁移控藏"理论新认识,经勘探实践,发现了延安气田,累计探明天然气地质储量6650×10~8m^3。页岩气方面,提出陆相湖盆具备页岩气成藏条件的地质认识,通过配套技术攻关,实现陆相页岩气突破。下一步,延长石油集团将继续坚持"稳油、增气、强化非常规"战略,推进"地质工程一体化"勘探开发模式,保障企业可持续发展。Shanxi Yanchang Petroleum （Group） Co., Ltd （hereinafter referred to as Yanchang Petroleum Group for short） has promoted theoretical and technical research of exploration and development of oil, natural gas and shale gas, in Ordos Basin. The coordinated development of various resources has achieved remarkable results. In the aspect of petroleum exploration, the theory of ＂alternate accumulation of oil＂ was put forward. Through quantitative simulation of oil transportation and aggregation, exploration breakthrough of Lower Yanchang Formation had been achieved, and proven geological reserves of 2.75× 10^8t had been found. In terms of oil development, by revealing dual mechanism of seepage-displacement of fractured ultra-low permeability reservoir, development technology of ＂modest and mild＂ water injection was established. The natural decline rate of oil fields decreased from 18.22% to 12.6%. Effective development of low-grade oil fields had been achieved. In natural gas exploration and development, by putting forward a new theory of＂ sand body distribution was controlled by the shoreline frequent migration in shallow water environment＂ and ＂the natural gas accumulation was controlled by the mature hydrocarbon source kitchen migration ＂ in the Upper Paleozoic, the Yan＇an gas field has been discovered and proved reserves of 6650×10^8m^3 in the southeastern Ordos Basin. In terms of shale gas, the geological cognition of lacustrine basin possessed shale gas accumulation conditions was proposed. Based on supporting technology research, breakthroughs of continental shale gas were achieved. In the future, Yanchang Petroleum Group would continue to adhere to the strategy of ＂stabilizing oil, boosting gas and intensifying unconventional resources＂. By keeping pushing forward the exploration and development mode of ＂integrated geological engineering＂, to ensure the sustainable development of enterprises.
