In order to improve the recovery percentage of the oil reservoirs and realize ifne division of oil reservoirs, a technique of subdivision of reservoirs and production control has been developed for producing wells with over six intervals. An electrically con-trolled testing and controlling gauge is run down the tubing-casing annulus and connected with the downhole adjustable bottom-hole regulator. The gauge will carry out direct analysis and judgment to the high production sections based on the monitoring data, so proper control may be realized over the liquid-producing capacity from each interval in one run, so that each interval will maintain proper lfow pressure and will give full play of its oil production potential. The study on the supporting subdivision technology has satisifed the sub-division and control of producing wells with over six intervals and achieves the goal of tapping the remaining oil.%为了提高油层的动用程度，实现油层的精细划分，研究出一种采出井6段以上细分层产量控制工艺。通过油管和套管之间的环形空间下入电控式测调仪，与井下可调式分层配产器进行对接，依据监测数据对高产液层段状态进行直观分析判断，实现一次下井完成各层段产液量的合理控制，使各层段均保持合理流压，充分发挥产油潜力。通过配套细分工艺的研究，满足了采出井6段以上的细分控制，达到了剩余油深度挖潜的目的。
