CURRENT STATUS AND FUTURE DEVELOPMENT OF OFFSHORE MULTIWAVE AND MULTICOMPONENT SEISMIC SURVEY IN CHINA

The development of multiwave and multicomponent seismic survey in the China Seas could be divided into two stages. The first stage, began in 1995, is the preliminary feasibility study with the mandate to systematically analyze the variation in p-wave and s-wave seismic parameters and their derived parameters in the Yinggehai Basin and Qiongdongnan Basin. Results suggest that it is feasible to apply the multiwave and multicomponent seismic technique in these basins. The second stage, started from 1998, is the stage of field test and indoor research. Three batches of multiwave and multicomponent seismic data (both 2D and 3D) are collected. Moreover, the multiwave and multicomponent seismic data processing and interpretation system is developed during this stage. Facts show that the method of multiwave and multicomponent seismic survey is effective in China Seas, and it can solve some difficult problems encountered in exploration and worth to be used in the other parts of China Seas. It could also be used to solve the key technical problems encountered in the oversea exploration by Chinese oil corporations.
