【摘要】 中国海域多波多分量地震勘探经历了2个阶段。第1阶段始于1995年,为前期可行性研究阶段,系统分析了莺歌海盆地、琼东南盆地纵横波地震参数及其衍生参数的变化规律。研究认为,多波多分量地震技术在莺歌海盆地、琼东南盆地的应用是可行的。第2阶段始于1998年,为现场试验及室内研究阶段。在这一阶段共采集了3批多波多分量地震数据(即有二维,也有三维),并研发了多波多分量地震数据处理与解释系统。中国海域多波多分量地震勘探取得了良好的地质效果,证明了多波多分量地震技术可以解决勘探中遇到的棘手难题。更多还原

【Abstract】 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.更多还原
