红岗油田高台子油藏相控随机水淹模型的建立

在测井资料综合解释和精细沉积微相研究的基础上,运用Petrel建模软件,建立确定性沉积微相三维模型,在此基础上应用相控随机建模技术,采用序贯高斯模拟进行储层水淹参数模拟,建立了红岗油田高台子油藏水淹模型,结果表明不同的沉积相区其油层的水淹程度和特征明显有差别。与非相控随机建模方法预测的模型对比分析表明,相控下的随机水淹模型比较符合油田开发过程中的水淹状况及规律,符合储层发育及其非均质性分布规律,可信度高,为该区调整挖潜提供了重要的地质依据。通过研究发现,相控水淹为油藏水淹规律及特征的预测判断提供了非常有用的新方法。

Wwterflooding Stochastical Model Constrained by Facies in Gaotaizi Reservoir of Honggang Oilfield

Based on the comprehensive interpretation of log information and the fine sedimentary microfacies, by using Petrel reservoir modeling software, a 3D model of determinacy sedimentary microfacies was established. The waterflooding model in Gaotaizi reservoir of Honggang Oilfield was built with the application of stochastic model constrained by facies and the sequence Gauss modeling. The result shows that the waterflooding degrees and features are obviously different in the different sedimentary facies areas. Comparative analysis with the other non-stochastic model constrained by facies shows that the stochastic waterflooding model constrained by facies is consistent with the flooding conditions and rules, it also consistent with the rules of reservoir development and aeolotropism distribution, the result is more reliable, which can provide the effective foundation to adjust and tap the potential for this area. The research shows that the waterflooding constrained by facies can provide the new approach to predict and judge the laws and characteristics of reservoir waterflooding.
