摘　　要：鄂尔多斯盆地苏里格气田是中国陆上发现的最大的天然气田,针对苏里格气田有效储层的具体特点,对三维地震储层预测关键技术做了具体介绍,与之前该地区实施的二维地震相比,该技术有效地解决了储层的平面和空间预测问题。并通过该次三维地震成果进行丛式井和水平井的具体井位部署,部署井完钻结果充分证实了三维地震在苏里格气田应用的有效性。应用结果表明:三维地震与二维地震相比,可以大幅度提高苏里格气田水平井有效储层钻遇率,尤其是可以大幅度提高I类井的有效储层钻遇率。Sulige Gas-field in Ordos Basin was the largest gas-field found in China.According to the effective reservoir characteristics of Sulige Gas-field,the key techniques for 3D-seismic reservoir prediction were introduced.Compared with the 2D-seismic interpretation used in the area,the technique can effectively solve the problems of reservoir prediction in the plane and space.Through the 3D-seismic achievements,the location of horizontal and cluster wells was deployed.The drilling results fully confirmed the effectiveness of the application of 3D seismic exploration in Sulige Gas-field.Application results show that compared with 2D-seismic exploration,the 3D seismic exploration can greatly improve the horizontal well drilling rate in Sulige Gas-field,especially it can greatly improve the Class I well drilling rate.
