油气田开发形势日益严峻, 开发地震技术随之取得了长足的发展。但这些发展有其理论和方法上的局限性, 迫切需要研究完善。在简要介绍了开发地震研究现状基础上, 分析了研究中存在的问题与矛盾。认为该项技术的发展应建立在储层各向异性和动态变化的研究基础上, 侧重于室内物理实验、多分量地震波场正演和参数反演。

The techniques of production seismology have been developed rapidly as the situation in development of oil and gas fields is becoming increasingly harsh. However, there is much room for improvement for the theories and methods in production seismology. Based on a review of production seismology, the paper discussed the problems existing in the current research work. The paper suggests that production seismology should be established on the ground of the research for reservoir anisotropy and its variability. The research emphasis of production seismology should be put on physical modeling, forward modeling for multi-component seismic wavefield, and parameter inversion. Some key modules in data processing and interpretation for multi-component converted wave data should be improved.
