Distribution and prediction of concealed reservoirs of Qianjiang Group in Qianjiang Depression

The geologic formation conditions and distributing regularities of concealed reservoirs and the types of known reservoirs of Qianjiang Group in Qianjiang depression are discussed.According to the special geologic and seismic circum stances of Jianghan saline lake basin, the integrated exploration methods were developed, which including building the geologic models of saline lake basin by the high accuracy sequence stratigraphy, predicting reservoir beds according to the impedence and gamma inversion results using 2D and 3D high resolution data, predicting whether the traps bear oil and gas or not applying MDI multi-prediction methods, comprehensively evaluating reservoirs combinating the structural background and oil-gas relationship.
