波阻抗反演方法在塔河碳酸盐岩储层预测中的应用
Application of Wave Impedance Inversion Methods in the Carbonate Reservoir Prediction in Tahe Oilfield
摘要
Abstract
This paper discusses the constrained sparse spike inversion, seismic characteristic inversion and stochastic inversion methods, analyzes the algorithm and the characteristics of the three methods in detail and applies the three methods in the carbonate reservoir in Tahe Oilfield. The results indicate that the constrained sparse spike inversion method keeps the amplitude, phase and frequency feature, producing the result in accordance with seismic reflection wave, but showing poor resolution. Stochastic inversion can objectively describe the heterogeneity reservoir of carbonate fractured-vuggy reservoirs, which overcomes the faults of continuity and stratification in constrained sparse spike inversion and seismic characteristic inversion methods. However, stochastic inversion method is difficult to obtain accurate variogram. The comparison of the three inversion method results reveals that seismic characteristic inversion method matches the reservoir better than the other two methods, thus it is an optimal method in carbonate reservoir prediction in Tahe Oilfield.关键词
