确定性预测模型 deterministic forecasting model
- 实践表明,该方法能够对相变复杂的陆相储层井间沉积微相不确定性进行表征,提高模型预测的可靠性。
Practice shows that this method is capable of characterizing the uncertainty of interwell sedimentary micro-facies of continental reservoirs with complex facies change to improve the credibility of model prediction. - 摘要针对饱和约束系统提出了一种鲁棒模型预测控制算法,分别考虑了多面体不确定性和结构反馈不确定性。
A robust model predictive control algorithm for saturated systems is proposed, in which polytopic uncertainty and structure feedback uncertainty are respectively considered. - 通过对哈萨克斯坦国某油田白垩系储层分析,经过岩石物理建模、AVO正演、楔状模型正演和确定性反演等一系列步骤,准确地预测了油水界面和储层分布情况,进一步证实了地质分析结果,从而减少了地震反演的多解性。
Through reservoir analysis for the Cretaceous formation of in certain oilfield in Kazakstan, the exact forecast has been made for the boundary of oil and water and the distributing condition of the reservoir based on the series of steps, such as geophysics modeling, AVO forward modeling, cuneal forward modeling and affirmatory inverse etc., and it is also proved that the conclusion of geology analysis is correct, so the diverse solution of seismic inverse can be redudced.
