【摘要】 莺歌海盆地中深层目标存在一定的钻前理论认识的问题,具体到地球物理的难点问题为:1)莺歌海盆地中深层是否存在有效储层;2)储层边界如何落实;3)不同水道填充岩性特征如何判断?针对这几个难点问题,单一的地球物理技术很难解决,所以采用沿层振幅类地震属性分析技术、频谱分解技术和波形聚类分析技术三种地球物理技术组合的方式来解决.通过技术研究结合莺歌海盆地底辟区中深层目标研究,落实了东方A区中深层目标储层及边界,判断了乐东A区水道砂储层的类型,为莺歌海盆地中深层寻找新层系和储量接替的实现打下良好的基础.更多还原

【Abstract】 Yinggehai Basin deep drill target there is a certain pre-theoretical understanding of the issues,specific to the difficult problem of geophysics:1) Yinggehai Basin the existence of effective reservoir in the deep;2)How to implement the reservoir boundary;3)Filled with different lithological characteristics to determine the river? For these difficult problems,a single geophysical technique is difficult to solve,so the use of classes along the layer amplitude seismic attribute analysis,spectral decomposition and waveform cluster analysis three kinds of combinations of geophysical techniques to solve.By combining research Yinggehai Basin diapiric areas in the underlying objectives of the implementation of the Target DF-A in the deep reservoir and boundary,to determine the LD-A area river sand reservoir type,Yinggehai Basin deep to find a new layer system and the realization of reserve replacement and lay a good foundation.更多还原
