【摘要】 研究区目的层段砂泥岩间互,含气储层厚度横向变化大,储层与非储层的纵波速度特征差异不明显。我们利用叠前地震资料丰富的信息,反演得到了对储层及所含流体更敏感、更有效的包括横波速度在内的各类属性参数数据体。对这些反演数据体进行交会解释,提高了对气层的识别与描述精度。更多还原

【Abstract】 The objective of the researched area is characterized by interbedded formation of sand-shale, great variation in lateral direction of reservoir thickness and little difference of P wave velocity between reservoir and non-reservoir. Various kinds of attribute parameter data are inverted to obtain the information of prestack seismic data, which are more available and sensitive to reservoir and fluid body. The inversion data volume is interactively interpreted to improve the identification and description precision on gas reservoir.更多还原
