Application of seismic reflection unique point in reservoir prediction
Yanhui Wang, Qin Yue-shuang · Petroleum Geology & Oilfield Development in Daqing · 2005
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.
