By analysising cost and output for low yield oil wells, in the paper, the method of flow switch is used to judge if the well bore has the oil flows, which change the traditional experienced method (touch the beam hangers temperature and look if it has the oil film) and the present automatic liquid level monitoring manner, and it is the closed-loop control and reduce the intensity of labour and the cost of the production. The hill-climbing mathematical method is considered as the most effective way.

论文中采用了流量开关的方法判断井口是否出油，打破了传统用经验判断(看抽油杆是否发热、是否附有油膜)的方法和现有的自动液位监测仪判断方法，形成了闭环控制，降低了劳动强度和减少了生产成本；并将数学方法上的瞎子爬山法用在了本优化控制系统中。
