全金属螺杆泵蒸汽吞吐注采一体化试油技术

摘要
试油排液是获得油田开发地层产能数据及参数的常用方法,而对于注蒸汽热采开发稠油井的试油排液,采用常规排液方法存在机抽排液进泵难、水力泵排液热损失大、橡胶定子螺杆泵无法用于高温井举升问题。文章提出了以全金属螺杆泵为核心的注蒸汽、热采一体化高温排液试油技术,设计了一体化排液管柱及热采配套工具,测试分析了不同介质黏度、转速条件下全金属螺杆泵工作性能。通过2口井现场应用表明,全金属螺杆泵最长生产周期达到18个月继续有效,泵效保持在50%以上,工作温度达到380℃,为稠油热采井高温举升、试油排液提供了新技术。
The development of heavy oil reservoir is of vital importance for stable production of oil fields. The acquisition of thermal production reservoir's stratigraphic productivity data usually relies on testing production. An integrated injection-production testing technique featured by all-mental screw pump is proposed in this paper, integrated injection-production pipe string and matching tools are designed,work performance of allmental screw pump is tested and analyzed. Field tests on two wells prove all-mental screw pump's maximum operation temperature is 380 ℃,screw pump can be used in integrated steam injection-test production of thermal recovery wells,the life has reached 18 months and the pump is still working with pump efficiency stabilized at 50%,which still meets the needs of test production of thermal recovery.
