大庆外围油田河道砂体储层预测技术及应用

Reservoir prediction technique of channel sandbody and its application in Daqing peripheral oilfields

基于地震理论及地震应用技术,针对外围油田不同的储层沉积模式及实际地震资料,建立地震正演模型。给出了目前地震资料的适用条件;对已经成形的属性分析技术进行了改进并联合地震反演技术对储层进行了精细描述;应用最新的分频解释技术预测储层的优势沉积相带;同时发展了以地震波特征点理论为基础的储层预测方法,在实际应用中取得了较好的效果。

On the basis of seismic theory and seismic application technology, aiming at different reservoir sedimentary patterns in Daqing peripheral oilfields and real seismic data, seismic forward model is established and applicable conditions of current seismic data are given. The existing attributes analysis technology is improved, and refined description of reservoir is done combining seismic inversion technique. Advantageous sedimentary facies belt of reservoir is predicted by applying newest frequency division interpreta tion technique. At the same time, a reservoir prediction method based on seismic wave＇s feature point theory is carried out,and a thieve the favorable effect in real practice.
