密井网条件下油藏压力监测系统优化部署方法
|
摘要
目前许多油田都经历了井网调整,多套井网重叠,原有的压力监测系统已不能满足密井网的开发条件,无法准确评价区块的压力水平.为此,综合考虑地层系数、产液、注水、综合含水等动静态特征对压力监测井点的影响,建立了压力监测系统优化部署模型,给出了压力监测系统部署方法及具体操作流程,兼顾井网油水井数比确定了监测比例,最终应用该方法结合密井网JC的实际资料对压力监测系统进行了优化部署,确定了该井网的合理监测比例,给出了压力监测系统优选方案.
At present,many oil fields have been through a series of well network adjustment, and the original pressure monitoring system cannot meet the conditions of the development under dense well network and accurately assess the pressure level of block.So considering the influence to monitoring wells from the formation capacity,production rate,injection rate, composite water cut and other static and dynamic characteristics,the optimal model of pressure monitoring system under close spacing condition was founded.The deployment method and specific operational procedure of the pressure monitoring system were given,at the same time the monitoring proportion was determined in consideration of oil-water wells number ratio. This method was applied to optimize the pressure monitoring system of close spacing JC, and reasonable monitoring proportion was given.The optimal program of pressure monitoring system was eventually obtained.
