抽油泵在使用中常常因断、脱、漏而发生早期失效。这类故障在江汉油田特别突出。据江汉油田1983～1984年6月的统计,由断、脱、漏而造成泵早期失效共149井次,其中泵断41井次,泵脱63井次,泵漏45井次。这不仅影响原油产量,而且还增加检泵作业井次和费用。 几年来,针对上述故障,我们不懈地探索寻找排除方法。经过反复分析和试验,终于找到了行之有效的方法,并且在生产中见到了可喜成效。 Pump in use often due to off, off, leakage occurred early failure. Such failures are particularly prominent in Jianghan Oilfield. According to statistics of Jianghan Oilfield from 1983 to June 1984, a total of 149 wells failed early due to breakage, off and leakage, of which 41 wells were cut off, 63 wells were removed from the well and 45 wells were drained 45 times. This not only affects the crude oil production, but also increases the inspection pump workover and costs. In recent years, in response to the above failures, we tirelessly explore the search for exclusion. After repeated analysis and testing, finally found an effective method, and saw gratifying results in production.
