摘要
莺歌海盆地岩石弹性物性的变化是有规律的。气层的纵横波速度比及泊松比远远低于水层和泥岩层。研究并开发了一系列的四分量地震资料解释方法 (如烃类检测方法等 )。总结出了一套适合于中国近海四分量地震勘探资料解释和应用的流程。四分量地震技术在改善莺歌海盆地的构造成像、浅层气层检测方面的效果是很好的。用泊松比预测了乐东 81等构造中深层的岩石物性和含气性 ,结果表明其勘探前景是比较好的。
Rock elasticity and physical properties in Yinggehai Basin change regularly. The v p/ v s and Poison's ratio of gas-bearing reservoirs are remarkably lower than that of water-bearing reservoirs and shale. Seismic data interpretation methods for different targets were developed. A workflow of interpretation and application for 4C seismic data was summarized in the paper. 4C seismic data can effectively improve structure imaging and shallow gas-bearing reservoir detecting. The study of petrophyiscal properties in structures such LD81 reveals that LD81 is a favorable prospect.
