摘要
地质模型的建立在数值模拟中至关重要。然而, 通过地质统计学建立的地质模型是一根据静态资料 (如岩心、测井和地震资料等 ) 生成的油气藏特性, 当数据在平面上不是近距离分布时, 得出的油气藏描述将有很大的不确定性。基于反演问题的理论研究得出, 油气藏压力资料, 特别是动态压力资料, 能够降低静态地质模型中的不确定性。通过几个实例, 证实了试井分析在改善这种不确定性方面所作的贡献, 从而进一步证明了试井分析在数值模拟中的重要作用。
It is very important on the numerical simulation to establish the geological model. However, the geological model is established with the geological statistics, which obtain the reservoir features by static data from cores, well logging and seism etc., and have great uncertainty for reservoir description when the data are not distributed at near distance on the plane. With the theoretic study of inverse problems, it is found the pressure data, especially the dynamic pressure data, can decrease the uncertainty of the static geological model. With real cases, it is demonstrated the contribution is made by well test analysis to improve the uncertainty. It is further proved the well test analysis plays important role on the numerical simulation.
