摘　　要：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 .The new technology of pressure testing in wells of two\|formation isolation and simultaneous pumping is introduced. It overcame the disturbances between two formations, also gained single\|formation pressure data in two\|formation merge pumping well by applying the technology in “Fang\|24 well”. We gained output of single\|formations directly or indirectly by switching single\|valve between double\|pumps, and gained the parameters of single\|formation and multi\|formations by analysing and caculating of the advanced appraise technology in testing wells, and calculated the yield of oil\|well by analysing unstable yield of “Fang\|24 well”, and mine“Fang\|24 well” because the well also have producing\|ability. Owing to the output of the well decrease progressively by time at stable pressure, we adjusted the well work\|system that reduced the output of the well, and effectively controled the production of the well. The technology possess general appltion value in the well of two\|formation isolation and simultaneous pumping.
