中国近海油气地震技术现状及展望

渤海海域复杂陆相沉积环境下的薄互层储层问题，南海高温高压、深层成像和深水勘探等一系列勘探难题制约了中国近海油气勘探进程。采取技术引进、合作研究和自主研究开发等多种形式加强了地震技术研究。包括多波地震、高分辨率地震技术在内的莺歌海盆地天然气勘探技术发现了6个气田。集成了多项新技术在内的琼东南盆地复式天然气藏地震勘探技术有效地提高了勘探成功率，发现了2个小型气田和4个含气构造。渤海河流相储层高精度预测技术可预测5m左右的薄储层，预测结果与钻井吻合度达79％。

Current Condition and Future of Petroleum Seismic Technique in China Offshore

There are some exploration difficulties in China offshore,such as thin-interbeds reservoir formed in continental facies sediment environment in Bohai Sea area,high temperature and high pressure in South Chian Sea,seismic tomography in depth and deep-water exploration in Sourth Chian Sea.The seismic technique research were strengthened by the techniques indraught,researching and development by cooperating or relying on ourselves.Six gas fields were found by the seismic exploration technique in Yinggehai basin.The exploration success ratio was improved by the seismic exploration technique for multiple gas reservoirs in Qongdongnan basin.Two small gas fields and four gas-bearing structures were found by this technique.The thin reservoir(about 5 meters) can be predicted by the high-precision seismic predicting technique for fluvial facies reservoir in Bohai basin,and the predicted results were inosculated with the drilled results.The development seismic techniques research will be strengthened besides the seismic exploration techniques,such as four-dimensional seismic technique,high-quality seismic technique,3D multi-components VSP,3D-4C and 4D-4C seismic techniques.
