近海四分量地震资料解释及应用
|
摘要
莺歌海盆地的岩石弹性物性的变化是有规律的。气层的纵横波速度比、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、浅层气层检测及岩石各向异性(裂隙预测)方面的效果是很好的。用泊松比预测了乐东8-1等构造中深层的岩性物性和含气性。乐东8-1、乐东22-1构造中深层的勘探前景是比较好的。
Some regularity was found in the variation of the rock elasticity in Yinggehai basin.Both the compressional wave velocity to shear wave velocity ratio and Poisson ratio for the gas reservoirs are much lower than those for water layer and mudstone.A series of four - component seismic data interpretation methods was developed,and a process suitable for China offshore four - component seismic interpretation and application was summarized.The four - com- ponent seismic technique has improvod the structure imaging,shallow gas reservoir and formation heterogeneity sur- vey considerably.The petrophysical property and gas - bearing characteristics were predicted for those structures such as Ledong 8 - 1 etc.by Poisson ratio.It was showed that the deep formations in Ledong 8 - 1 and Ledong 22 - 1 had a promising exploration prospect.
