Characterization Methods Study Of Interior Reservoir And Interlayer Of Buried Hill

Taking the Jizhong depression as example, this dissertation mainly used geophysical ways to research the description and characterization methods of reservoir and interlayer inside buried hill. The study mainly from the following several aspects:First, we study the interlayer inside Renqiu buried hill. Integrating 3D seismic data along with geologic and well logging data, we establish the nonlinear mapping model between interlayer thickness and lateral attribute parameters at well position. Then we make prediction of interlayer inside the buried hills with the model. The result shows that the technique is of high precision and reliability.Secondly, several methods of porosity prediction was introduced, and then by well data interpretation, horizon interpretation, attribute extraction optimization analysis, the porosity distribution was predicted of the study area of the Ordovician Fengfeng group inside Suqiao buried hill using the Nonparametric Regression method.Thirdly, taking the shale content of several wells calculated by well curve data as sample, the shale content distribution of the whole study area was predicted. And, integrating the porosity distribution, the reservoir characteristic was comprehensively analyzed.Finally, a layer without well samples inside Suqiao buried hill was studied using integrated attribute processing method, and the favorable areas were predicted by analyzing the results.
