Application of the log constrained inversion in predicting the turbidite sand body in Niuzhuang area

According to the characters of turbidite sand body of Niuzhuang sub-sag,such as thin reservoirs,deep embedding,unstable distribution,high concealment and etc,and based on expatiating on the principle,method and key technique of the log constrained inversion,this paper summarized the inversion experiments fitting for the reservoir exploration,including multifactor calibration of synthetic seismogram,the found of original impedance and the choice of inversion method.In practical application,a favorable effect has been acquired,and this provides a good reference for the reservoir prediction and description of turbidite sand body in other areas.
