油田中后期稳产规划方法

在文1]的基础上本文提出了一个编制油田中后期稳产规划的方法。前文以月报附表为基础数据,通过多步递阶物理结构分析,应用带滤波功能的动态系统辨识方法,建立了产油量、产水量、地层压力与措施用量间的动态关系式,为研究最佳规划模型创造了条件。在满足国家要求前提下,以提高经济效益和水驱采收率为追求目标,建立了一个最优控制模型,通过它的求解可自动地编制出稳产规划。文中还研究了该模型的求解方法,并考查了它在应用中的效果。

A METHOD FOR STABLE OUTPUT PLANNING DURING THE MIDDLE TO LATE WATERFLOODING STAGE

A systematic model for stable oil outputs planning during middle to late waterflooding stage has been proposed,based on the previous article. In that paper,a set of dynamic relationships between dynamic performances (oil production rates,water cut,reservoir pressure) and stimulation measures were formulated by the use of the data listed in the monthly reports through a multi-step physical analysis and system identification approaches with filtering functions which are basic equations for studing this subject. Under the condition of meeting the needs for oil, production defined by national planning, an optimal control model has been developed to maximize economical profits and secondary oil recovery, by which the planning could be fulfilled automatically by solving it. Calculation procedures are suggested and, actual field application effects are examined.
