摘要(Abstract)：
目前, 大庆外围油田的开发主力油层正逐渐由葡萄花油层向扶余油层过渡, 扶余油层主体发育带预测难度加大, 已有方法预测精度已不能适合目前评价和开发的需要, 急需一种识别扶余油层主砂体发育带的储层预测方法。据此提出了一种利用地震反射特征点法预测砂岩厚度的新方法, 在肇源油田源35区块进行了尝试, 钻井成功率在75%左右, 取得了满意的效果, 该方法可行。
At present, the main oil layers are gradually transferred from Putaohua into Fuyu in Daqing marginal oilfields.The prediction of the main developed belt in Fuyu oil reservoir is rather difficult, the prediction accuracy of the existing methods cannot meet the requirements of present evaluation and development,so it is urgent to develop a new predicting method to recognize this belt. Considering the above need,a new method to predict sandstone thickness is established by means of seismic reflection characteristic point,this method has been putted into operation in Yuan 35 seismic site of Zhaoyuan oilfield whose drilling success ratio is about 75%, favorite effect has been obtained, so the method is proved feasible.
