油气勘探中常规地球物理方法的发展

含油气储层的勘探方法研究,是地球物理研究的重要方面。本文针对国内外各种常规地球物理勘探方法进展状况,尝试将各种地层勘探方法进行归纳,并从数据精度、勘探成本和适用范围方面对各种方法进行评价分析;在此基础上对油气勘探方法的发展方向及未来几年内可能取得突破性进展的研究领域等热点问题进行了探讨。研究表明,面对各向异性介质,必须大力发展多波多分量勘探技术、P-S转换波勘探技术、强化各向异性介质正、反演模型研究及发展勘探技术,进一步提高勘探精度、降低勘探成本。

Development of conventional geophysical methods in oil/gas exploration.

The study of exploration methods for oil/gas-bearing reservoirs is important aspects of geophysical study. The paper tried to summarize the different methods for reservoir exploration based on developed situation of different conventional geophysical exploration methods at home and abroad, and conducted evaluation in such aspects as data precision, exploration cost and adaptive scope etc; on that basis, the paper discussed the key issues such as prospect of development in oil/gas exploration methods and research domain that can make breakthrough in next several years. The studied results showed that, in anisotropic medium, we should make efforts to develop multi-wave and multi-component exploration techniques, PS-converted wave exploration technique, strengthen the study of forward and inversion models in anisotropic medium and develop associated exploration technique and further improve exploration precision as well as reduce exploration costs.
