基　　金：螺杆泵采油技术在低渗透油田中的开发应用研究

摘　　要：陕北地区油井普遍特点是井深、低压、低渗、高耗能且井液成分复杂。螺杆泵作为一种容积泵,在该地区应用具有一定的优势。本文针对螺杆泵的特点,讨论了螺杆泵在陕北地区推广的可行性,研制了螺杆泵采油系统,通过对该地区油井进行试验和分析计算,选取了螺杆泵的型号、抽油杆的转速、下泵深度以及扶正器的布置。对5口油井的试验结果表明:螺杆泵的平均吨液百米耗电比抽油机低0.408 kwh,节电率为34.9%。Oil well area of north of Shanxi Province , its general characteristics is deep, low pressure, hard to infiltrate, highly energy-consuming and complex liquid composition. The screw-pump has certain advantages if used in this area as a kind of volume pump. This paper links up the characteristic of screw-pump, discussed feasibility of using screw-pump in the area, developed the pumping system .By choosing the five wells of this area to carry on the test and analyzing, we chose the type of screw-pump, worked out the rotational speed, pump setting depth, centralizer distribution. The research indicate that： compared resulting data with the former, mean electricity consumption of this system is lower than 0.408kwh, the electricity saving rate is 34%.
