Study On The Fine Structural Interpretation And Reservoir Of Xinan Zhuang Buried Hill In Jidong Oilfield

After many years of exploration and geological research in Xinan Zhuang buried hill,there are still many difficulties in exploration,mainly including:(1)Due to the difference of stratigraphic sedimentary time and the difference of lithology,the lateral velocity changes dramatically,which leads to the great difficulty in the fine interpretation of the structure.(2)The carbonate reservoir in this area is mainly composed of fracture and fracture cavity.Because of the quality of seismic data,the fracture and the hole have no obvious reflection anomaly in seismic profile,which brings great difficulty to reservoir prediction.This dissertation in the Mesozoic and Paleozoic in each stratum seismic data fine structural interpretation on the basis,the forward technology and velocity analysis,to carry out the top of buried hill and reservoir insider research.Then,a variety of reservoir prediction techniques are applied,such as the technique of body curvature and the method of extracting the anisotropic strength properties,to study the fractured carbonate reservoir and to determine the favorable development zone of the reservoir.Finally come to the conclusion that is suitable for the buried hill structure in the region and technical approaches to the study of the reservoir.
