Progress in China's Unconventional Oil & Gas Exploration and Development and Theoretical Technologies
摘要
Abstract
The new century has witnessed a strategic breakthrough in unconventional oil & gas.Hydrocarbon accumulated in micro-/nano-scale pore throat shale systems has become an important domain that could replace current oil &gas resources.Unconventional oil & gas plays an increasingly important role in our energy mix.Tight gas,CBM,heavy oil and asphaltic sand have served as a key domain of exploration &development,with tight oil becoming a'bright spot'domain and shale gas becoming a'hotspot'domain. China has made great breakthroughs in unconventional oil & gas resources,such as tight gas,shale gas, tight oil and CBM,and great progress in oil shale,gas hydrate,heavy oil and oil sand.China has an estimated (223~263)×108 t of unconventional oil resources and (890~1260)×1012 m3 of gas resources. China has made a breakthrough for progress in unconventional oil &gas study.New progress achieved in fine-grained sedimentary studies related to continental open lacustrine basin large-scale shallow-water delta sand bodies,lacustrine basin central sandy clastic flow sediments and marine-continental fine-grained sediments provide a theoretical basis for the formation and distribution of basin central reservoir bodies. Great breakthroughs have been made in unconventional reservoir geology in respect of research methodology & technology,multi-scale data merging and physical simulation of formation conditions. Overall characterization of unconventional reservoirs via multi-method and multi-scale becomes increasingly popular and facilitates the rapid development of unconventional oil & gas geological theory,method and technology.The formation of innovative,continuous hydrocarbon accumulation theory,the establishment of the framework of the unconventional oil & gas geological theory system,and the determination of the implications, geological feature, formation mechanism, distribution rule and core technology of unconventional oil &gas geological study lays a theoretical foundation for extensive unconventional oil &gas exploration and development.Theories and technologies of unconventional oil & gas exploration and development developed rapidly, including some key evaluation techniques such as'sweet spot zone'integrated evaluation and a six-property evaluation technique that uses hydrocarbon source,lithology, physical property,brittleness,hydrocarbon potential and stress anisotropy,and some key development &engineering technologies including micro-seismic monitoring, horizontal drilling & completion and "factory-like"operation pattern,"man-made reservoir"development,which have facilitated the innovative development of unconventional oil & gas.These breakthroughs define a new understanding in four aspects:①theoretical innovation;② key technologies;③ complete market mechanism and national policy support;and ④ well-developed ground infrastructure,which are significant for prolonging the life cycle of petroleum industry,accelerating the upgrade and development of theories and technologies and altering the global traditional energy structure.关键词
