钻井泵瞬态波动压力研究

The study of the transient surge pressures on drill pump

介绍了国外在井内波动压力方面的研究情况,分析了影响井筒内波动压力的主要因素,对比了中原油田在1988年8月至1989年9月在全尺模拟实验井及参2井进行的大规模试验中采集的部分数据。通过对钻井泵瞬态波动压力间的比较分析,对可能出现的问题提出了相应的预防及处理方法。

Introduced the research status on the borehole surge pressures from abroad, analyzed the dominant factor which influence the borehole surge pressures, compared the partial data acquired in full hole simulated experimental hole and the experiment in Well Can 2 was conducted by Zhongyuan Oilfield from August, 1988 to September, 1999. Proposed appropriate measures to protect and treat the problems after the comparison between transient surge pressures.
