电动潜油螺杆泵采油系统特点及应用

Technical feature and application of electric submersible progressing cavity pump

随着油田开发的逐步深入 ,为满足油田开发的需要 ,各种难动用储量 (稠油井、出砂井 )逐步投入开发 ,给采油工艺的配套提出了新的要求。电动潜油螺杆泵的研制就是在上述背景下提出的。电动潜油螺杆泵与地面驱动螺杆泵、潜油电泵相比具有许多特点 ,经现场应用表明 ,对于稠油出砂的斜井、定向井和水平井的开采具有无可比拟的优势。

Along with the in-depth development of oil field, various difficult reserves (high viscosity oil well, sand well) were developed step by step to satisfy the needs of oil field develops, new requirement has been put forward to form a complete technology of oil extraction. The R&D of Electric Submersible Progressing Cavity Pump (ESPCP) is put forward in such background. Comparing with Surface Drive PCP and ESP, ESPCP have a lot of characteristics. It shows incomparable advantages in the application of slant wells, horizontal well and directional well, etc.
