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24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24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.

The new technology of pressure testing in wells of two-formationisolation 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.
