小洼油田为注蒸汽和蒸汽驱开发的稠油区块,其原油性质具有“两高、两低”的特点。由于油井油稠、出砂制约了油田开发水平的提高,进行螺杆泵排砂技术研究和现场试验,并不断完善配套工艺技术。通过研究应用和实践表明,螺杆泵采油技术在小洼油田已经成为一项成熟采油技术。 The Xiaowa oilfield is a heavy oil block developed for steam injection and steam flooding. Its crude oil has the characteristics of “two highs and two lows”. Due to thick oil wells, sand production constraints restrict the development of oil fields, the screw pump sand technology research and field trials, and continue to improve the matching process technology. Through the research application and practice, it has been shown that the screw pump technology has become a mature oil production technology in Xiaowa oilfield.
