| 摘 要： | 以薄层砂体的识别为目的所进行的地震反演．通常由于地震频带宽度的限制．采用普通地震资料直接进行反演的结果．其精度和分辨率都不能满足油田开发对簿砂层识别的要求。然而．采用测井资料丰富的高频信息和完整的低频成分补充地震资料有限带宽的不足，综合地质认识等信息作为约束条件，可以得到高精度的波阻抗资料。根据XX地区X56区块实际资料情况和地质特点．应用测井约束反演技术对其进行了储层反演，反演结果与钻井情况符合良好，为该油藏开发方案部署和油田生产提供依据。

| Abstract: | The seismic inversion aimed to recognize the thin layer bandwidth was restricted by the limited seism,accuracy and resolution of the results that carried on by direct seismic inversion was low,so it could not meet the requirements of oilfield development.However,applying log data-rich high-frequency information and integrated low frequency components of seismic data can retrieve the defacts of limited seismic bandwidth,the high accurat wave impedance data can be obtained by comprehensive geologic knowledge.... |
