[Abstract]:Seismic inversion technology is widely used in reservoir prediction and fluid detection. In this paper, seismic inversion technique is further applied to reservoir monitoring based on time-lapse logging data. The principle and method of high precision wave impedance extrapolation inversion and Seimpar nonlinear logging curve inversion are given, and then the 3D seismic data and acoustic logging data are used as input, taking practical application as an example. The 3-D wave impedance data volume with high accuracy is obtained, and the 3-D wave impedance data volume and time-shift logging data are used as input, and the pseudo natural potential and pseudo resistivity data volume of different periods are obtained by Seimpar nonlinear pseudo logging curve inversion. Furthermore, the time shift logging 3D data volume is used to predict the distribution of remaining oil and to realize reservoir monitoring. The application results show that the 2D and 3D quasi logging data provided by the combination of high precision wave impedance extrapolation inversion and Seimpar nonlinear logging curve inversion are used for residual oil distribution prediction and reservoir monitoring. The coincidence rate of more than 2m single layer sandstone is over 80%. According to this result, 32 infill wells are deployed, all of which are successful.
