合理的间抽制度对于提高低效油井整体经济效益十分重要,而抽油泵环隙漏失对间抽制度的影响不可忽视。通过分析抽油泵环隙漏失对间抽井不同生产阶段的影响发现,根据漏失情况延长抽油时间有助于提高间抽井产量,适当放大冲次有利于减小漏失的影响,提高间抽井工作效率。在此基础上对间抽井间抽制度进行了优化,经现场验证效果良好。该研究对优化油井间抽制度具有一定借鉴意义。
Reasonable intermittent pumping period is critical to increase economic benefits of low efficiency wells, and the effect of pump leakage on intermittent pumping period should not be ignored. By analyzing the influence of annular leakage on different production stages of intermittent pumping wells, it is found that appropriately extending the pumping time according to annular leakage is favorable to increase production of intermittent wells, and properly improving the stroke frequency is conducive to reduce the impact of annular leakage and to improve the working efficiency as well. Intermittent pumping period has been optimized on this basis and is proved to have good effect through field application.
