储层合采动态分析方法探讨

The Study of the Dynamic Analysis Method of the Commingled Production

摘要: 本文提出一种分析不同储层合采效果的方法。本方法主要是建立在油藏物性及流体性质、水体能量、开发方式等数据的基础之上，将数值分析与油藏工程相结合，计算得到合采时各小层随时间变化的生产动态数据(产量比例、压力变化等)。这种动态分析方法简便易行，结果较为准确，对于判断合采效果和主要影响因素，从而制定合理的开发方案以及后期的产液剖面调整策略均具有一定的实际意义。

Abstract: In this article, we developed a new kind of method to estimate the dynamic effects of the commingled production of different reservoirs. This method is mainly based on the data of the physical and fluid properties, aquifer, development mode, etc. Through the combination of numerical analysis and reservoir engineering, we can figure out the changeful dynamic data in every layer (the proportion of the production rate, the formation pressure, etc.) as the time changes. This method is convenient to apply. It can give the accurate results and has certain practical application significance for us to judge the feasibility, the effect and the influencing factors of commingled production, so as to formulate the reasonable development plan or the production profile adjustment strategy.
