中国石化油藏地球物理二十年发展与思考

Development and perspective of reservoir geophysics in Sinopec in the past 20 years

油藏地球物理技术是综合应用多种地球物理资料与油藏动静态信息进行复杂油藏精细表征和动态监测的跨学科技术,对于提高油藏的储量动用程度和提高采收率具有重要的意义,是当前地球物理技术的重要发展方向。系统回顾了中国石化油藏地球物理提出的背景和过去二十年的发展历程,梳理了油藏地球物理技术系列,总结了在油藏地球物理基础研究、井中地球物理技术、多尺度资料联合反演、地球物理约束确定性建模、时移地震剩余油气预测、地震地质工程一体化、微地震油藏监测等方面的技术创新和应用效果。面对中国油气田勘探开发的深层、深水、非常规及老油田(“两深一非一老”)形势和一体化、智能化、绿色化挑战,油藏地球物理在油气产业技术致胜阶段仍然大有可为,要持续创新油藏地球物理技术,井、震、动、模一体化联合和人工智能应用,构建高水平的油藏地球物理勘探开发一体化、地质工程一体化解决方案,支撑油藏全生命周期建设。

As an inter-disciplinary technology which integrates a variety of geophysical data and dynamic and static information of reservoirs into detailed characterization and dynamic monitoring of complicated reservoirs,reservoir geophysics is of great significance to improved reserve utilization and recovery efficiency and thus is an important direction of geophysical technologies.We give an overall review of reservoir geophysics in Sinopec in the past two decades and a series of geophysical techniques,including technical innovations and their application from the perspectives of fundamental geophysical research,borehole geophysics,multi-scale joint inversion,geophysically constrained deterministic modelling,time-lapse seismology for remaining oil and gas prediction,seismology-geology-engineering integration,and microseismic monitoring.In the context of petroleum exploration and development in deep water and deep zones,unconventional reservoir exploration and development,enhanced oil recovery in mature fields,and challenges of integrated,intelligent,and green technologies in China,there are still bright prospects for reservoir geophysics in petroleum industry.It is suggested continuing innovations in reservoir geophysics,integration of well,seismic,dynamic,and modelling data,and artificial intelligence application and establishing high-level solutions to exploration-development integration and geology-engineering integration to support life-span reservoir construction.
