近海天然气藏地震预测技术及应用
|
摘要
中国近海油气勘探已有近 30年的历史 ,先后发现了几个构造油气藏。随着勘探难度越来越大 ,如何发现岩性油气藏和岩性—构造复合型油气藏成为我们的重要研究课题。其中 ,运用地震信息识别 (或称预测 )油气藏技术则是我们的首选课题。近年来 ,我们在这方面开展了大量的研究工作 ,取得了较好的地质效果。研究表明 :亮点技术、AVO技术、道积分技术和四分量地震技术是莺歌海盆地天然气识别的有效技术。综合运用上述技术 ,我们先后预测了储量可观的 YC13- 1、DF1- 1、L D2 2 - 1、L D15 - 1等大型或中型气田 (均已被钻井证实 ) ,取得了显著的经济效益和社会效益
There are thirty years of history for chinese offshore oil gas exploration and some structural oil gas reservoirs have been successively found. Because difficulty of exploration became more and more, how to find lithologic reservoir and lithologic structural compound reservoir is our important studying task, among which how to use seismic information to distinguish (or predict) reservoir is our first research task. In recent years, we developed a large amount of research jobs in this domain and achieved many geologic results. The research showed that "bright point" technique, AVO, trace integration technique and 4 C seismic technology are effective techniques for distinguishing gas reservoir in Yinge Sea Basin. Comprehensive utilization of the above mentioned technology, we predicted successively large scale or middle scale gas field with considerable reserve: Yacheng 13 1, Dongfang 1 1, Ledong 22 1 and Ledong 15 1, etc., which were proved by drilling, achieving significant both economic and social benefits.
