小泵深抽技术在川中应用前景初探

A DISCUSSION OF THE PROSPECT OF THE APPLICATION OF SMALL PUMP TECHNOLOGY IN THE CENTRAL SICHUAN OIL FIELD

本文对川中地区的小泵深抽井进行了分类，总结了小泵深抽技术在低渗透、低产能油层中应用时油井的生产特点及存在的问题，剖析了造成深抽井低泵效的原因，指明了提高泵效的途径。认为小泵深抽技术将是川中未来最重要的采油工艺之一，在油田稳产中将起重要作用。

Abstract This paper gives a classification of small pump used in oil wells in the central Sichuan oil field, and summarized the production characteristics and problems, when small pump technology is used in the production of a low permeable and low capacity reservoir, analyzed the reason of low pump efficiency, and points out the way to improve the pump efficiency. This paper demonstrates that small pump technology will be one of the most important production technology in central Sichuan oil field, and contributes much to the stable production of the oil field.
