英文摘要：

As the geology of oil and gas exploration in our country has become increasingly complex. it is essential to carry out the geological and geophysical multi-disciplinary integrated studies to fully know the object and strengthen the understanding of underground geological body. The resolution of conventional seismic inversion is not high due to the impact of noise and band wavelets.This makes the inversion results can not describe and recognize formation accurately. So,it is urgent to improve the accuracy of lateral lithology prediction and the description of geological objects to understand the spatial distribution of the target formation.By using the vertical high resolution of logging data and the clear reflection of the lithology and oil characteristics of geological data,The paper combined both together to predict reservoir and accurately get the main lithology,pore types and oil characteristics in this area according to the core image,casting thin sections and scanning electron microscopes of three coring wells. And the reservoir and non reservoir are divided into seven kinds. Then the wave impendance range of favorable reservoir can be calculated by analyzing the cross-plot of well logging. In the last,The paper used three coring wells to verify the result in seismic inversion attribution map and section map,and obtained good result.The wave impedance threshold of favorable reservoirs which obtained from cross-plot is applied to inversion profiles to predict reservoir. Otherwise,the inversion profile of other several wells is used to validate the result of prediction. And the oil layers ＇distribution characteristics of verification wells are consistent with favorable reservoirs＇. It indicated that the effect is good. Compared to conventional three disciplines combined inversion,this paper not only use the macro understanding of geological data but also add the microscopic geological information in seismic impedance inversion.So,it can reduce the multiple solutions of reservoir inversion and it is signif
