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.
