在第一台经过改造的У8—3型泥浆泵于1973年4月26日开始由32166钻井队进行工业试验並取得了较好的使用效果后,管理局从1974年起在全油由推广使用。现已改造完成的有89台,正在使用的28台由14个钻井队使用,其中2个队已调走。为了总结经验,进一步推动技术改造工作,我们在1975年4月,对油田10个钻井队试验和使用改造泵的情况作了一次回访调查。现将这一阶段的试验和使用情况综合如下。
After the first modified У8-3 mud pump started its industrial trial by the 32166 drilling crew on April 26, 1973 and achieved good results, the authority started to promote the use of the whole oil from 1974 onwards . Now 89 have been completed transformation, the current 28 are used by 14 drilling crew, of which two teams have been transferred away. In order to sum up our experience and further promote technological transformation, we conducted a follow-up survey in April 1975 on the trial and modification of 10 drilling rigs in the oilfield. Now this phase of the trial and use of the situation are summarized below.
