摘要
海上油田开发中后期通常面临平台液处理能力制约油藏产能充分释放的问题,对平台扩容改造提升液处理能力是该类油田开发后期的重要举措。为实现平台扩容潜力的快速优化评价,综合考虑油田产液能力增长趋势和平台有效期,以平台有效期内保证油田可采储量全部采出为原则,提出了海上油田平台扩容增量优化模型,并通过将油田无因次采液指数与含水率的定量关系离散转化为油田产液能力与时间的离散定量关系,实现了上述优化模型的求解。X油田计算实例证明了文中方法的有效性和可操作性。该方法仅需油田日产液量、日产油量等基础动态数据,资料需求简单,计算简便、快捷,可广泛应用于海上中高含水油田平台扩容潜力的快速优化评价。
Due to the ability of platform liquid treatment,the reservoir liquid production capacity usually cannot be fully released in the medium-high water-cut offshore reservoir,so improving the platform liquid treatment ability is an important measure.Considering the increasing trend of oilfield liquid production capacity and the validity period of the platform to ensure the recoverable reserves of oilfield in the validity period of the platform,the model for optimizing the platform expansion potential was proposed.In order to solve the optimization model,the quantitative relationship between liquid production capacity and time was proposed based on the relationship between liquid production capacity and water cut.The calculation result for X Oilfield shows that the method is effective and operable.The proposed method only requires daily production data to calculate,which is accessible and convenient,showing a broad application prospect in offshore oilfield.
