石油地震地质学自20世纪80年代初被提出后,随着应用地球物理技术的进步而不断发展,其目标是发现油气田和提高油气藏采收率。由于缺少独立的理论体系,石油地震地质学目前还不能成为一门真正的学科,而是一个利用地球物理技术解决石油地质学和油藏描述问题的技术集成。其目前的发展表现出3方面特点:研究技术多样化;井震结合使研究精度不断提高;研究领域由油气田勘探向油气藏开发发展。地震资料的分辨能力、地震反射信息地质意义的认识、地震资料的地质解释模式是制约地震资料在地质研究中应用的3个关键问题,也是石油地震地质学研究需要解决的关键问题。文中对石油地震地质学的发展提出4点展望:建立独立的理论体系;多学科、多尺度相结合;等时沉积单元及其地震响应特征研究;由储层地质研究向烃类检测发展。这也是今后石油地震地质学研究需要努力的方向。
Geophysics of petroleum seismology Since its introduction in the early 1980s, geophysics has evolved with the advancement of geophysical applications, with the goal of discovering oil and gas fields and enhancing oil and gas recovery. Due to the lack of an independent theoretical system, geophysics of petroleum seismology can not yet become a real subject at present, but a technical integration that uses geophysical techniques to solve the problems of petroleum geology and reservoir description. Its current development shows three aspects: the diversification of research techniques; the combination of well and earthquake to improve the research precision; the research field from oil and gas exploration to the development and development of oil and gas reservoirs. The ability to distinguish seismic data, the geological meaning of seismic reflection information, and the geologic interpretation mode of seismic data are the three key problems that restrict the application of seismic data in geological research. They are also the key issues to be solved in the research of petroleum seismic geology. In this paper, we put forward four perspectives on the development of petroleum geology: establishing an independent theoretical system; combining multidisciplinary and multi-scale; isochronal sedimentary units and their seismic response characteristics; and from hydrocarbon reservoir geology to hydrocarbon detection and development. This is also the direction that needs to be worked on in the future from the research of petroleum seismology and geology.
