Productivity Prediction Methods of Low Porosity and Permeability in Deep Reservoir in Nanpu Sag

以地质认识为指导,充分利用岩心、测井及试油试采资料,开展低孔隙度低渗透率储层岩石物理的孔隙结构表征分析,结合常规测井资料,建立连续定量表征的储层品质评价方法,进一步考虑不同工作制度及配产方式,在储层品质评价的基础上,采用不同的特征产能系数图版建立产能预测模型。形成了深层低孔隙度低渗透率油气藏基于储层品质评价及不同工作制度的产能预测方法。生产应用中评价多口井资料,产能预测结果与实际生产情况吻合,取得较精确的储层综合评价效果。

Based on understanding geology and making full use of core, logging and oil test data, analyzed are pore structure characterization of low porosity reservoir. Combined with conventional logging data, reservoir quality evaluation method of continuous quantitative characterization is established. Considering with a different system of work and production methods, on the basis of the classification of the fine reservoir, built is productivity prediction model with different characteristics capacity factor plate. Based on reservoir quality evaluation and different operating systems, the methods of low porosity and permeability in deep reservoir capacity in Nanpu sag is proposed. Several wells data are explained in production, of which capacity forecast results coincide with the actual production, it obtains more precise and effective reservoir evaluation results.
