摘　　要：结合苏里格气田苏6区块测井及高精度三维地震资料,综合运用精细地震构造解释、地震属性和储层反演等技术手段,开展河流相储层预测研究。研究结果表明:振幅类属性对于苏6区块砂体比较敏感,如均方根振幅属性;复地震道属性对于该区河流相预测较为敏感,如瞬时相位属性。地球物理反演结果表明,研究区盒八下段为砂体主要分布层段,有效砂体发育广泛,可作为有利储层。Based on well logging and high precision 3D seismic data of Su 6 block in Sulige gas reservoir, the fluvial reservoir prediction research is studied by comprehensive technical methods of fine seismic structural interpretation, seismic attributes and reservoir inversion. The results show that the sand in Su 6 block can be better predicted by amplitude attribute, as root mean square amplitude attribute. Compound ground seismic attribute is superior in the identification of channel, as instantaneous phase attribute. The geophysical inversion results show that the sand- stone distributes in lower Hs formation, and effective sand bodies are widely developed, which can be used as a fa- vorable reservoir.
