EXPLORATION OF SUBTLE OIL AND GAS RESERVOIR IN BLOCK KD32-33, XINTAN OIL FIELD, THE BOHAI BAY BASIN

The block KD32-33 in Xintan Oil Field of the Bohai Bay Basin has already come into the stage of subtle oil and gas reservoir exploraion.The seismic prediction of thin-bedded fluvial sandbodies is the key for rolling exploration and exploitation in this area.Applying the Conseis complex oil and gas reservoir forecast system which has not been generalized,the reconstruction of well-log and the reservoir prediction of texture-logging constraint nonlinear inversion are made.Thin-bedded sandbodies are effectively recognized.The planar distribution of sandbodies is predicted,instructing the rolling exploration and exploitation of oil and gas.The attainment rate is confirmed high by drilling wells.
