阐述了适用于两油层分采同抽井的测压技术 ,该技术应用于芳 2 4井 ,获得了该井的单层压力资料 ,通过关掉两泵之间的单流阀 ,直接或间接获得该井各分层的产液量 .利用常规的试井评价技术分析和计算 ,得到了该井各分层及合层的储层参数 ;利用单层及多层不稳定产能分析方法进行了产能预测 ,预测结果表明芳 2 4井仍具备一定的生产能力 ,可继续开采 .针对该井在给定流压下产量随时间递减的情况 ,提出了调整抽油井工作制度 ,适当降低日产油量的措施 ,有效地指导了该井的生产 .此技术对两油层分采同抽井具有普遍应用价值
This paper describes the pressure measurement technique applied to the two oil reservoirs, which is applied to Fang 2-4 well and obtains the single-layer pressure data of the well. By turning off the single-flow valve between the two pumps, directly or indirectly Get the production of the stratified fluid well.Using the conventional well evaluation technology analysis and calculation, get the stratified and combined reservoir parameters of the well; the use of single and multi-layer unstable capacity analysis method Prediction results show that Fang 2 4 well still has some production capacity and can continue mining.Aiming at the situation that the production of this well decreases with the passage of time under a given flow pressure, it is proposed to adjust the working system of pumping wells and reduce the daily output of oil Of the measures to effectively guide the production of the well.This technology has the common application value of two sub-reservoir mining and pumping wells
