我国陆上深层油气资源丰富,但探明率低,储量动用程度低、采出程度极不均衡,规模勘探和效益开发面临诸多重大科技难题。针对深层勘探开发面临的理论技术难题,中国石油天然气股份有限公司于2014年7月批准设立了“深层油气勘探开发关键技术研究”(编号:2014E-32)重大科技专项进行专题攻关研究。通过3年的攻关,专项取得了8项重要创新成果。成果一:创新发展了深层勘探理论与地质评价技术(1)建立了深层海相天然气多阶段、多途径复合
In our country, deep oil and gas resources are abundant on the land, but the exploration rate is low, the utilization of reserves is low and the degree of recovery is extremely uneven. Therefore, the exploration of scale and benefit development are facing many major scientific and technological problems. In light of the theoretical and technical challenges of deep exploration and development, PetroChina approved the establishment of a major research project on key technologies for deep exploration and development of oil and gas (No. 2014E-32) in July 2014. Through three years of research, special made eight major innovations. Outcome one: innovation and development of deep exploration theory and geological evaluation technology (1) established a deep multi-phase marine gas, multi-channel complex
