摘要

塔河油田超稠油油藏为奥陶系缝洞型碳酸盐岩油藏,非均质性极强,机抽井液面呈逐年下降趋势,稠油电泵更适合深抽生产。通过对25丼次深抽电泵进行评价,列举5个实例分析,得出油井累产液、转深抽前生产方式及地质特征均为主要效果影响因素。超稠油深抽要依托注水指示曲线,在充分认识油井地质特征的情况下,优选高扬程电泵机组,可最大限度提高深抽潜力。

Abstract

The ultra-heavy oil reservoirs in the Tahe Oil Field are Ordovician fractured and vuggy carbonate reservoirs lack of heterogeneity. Since the level of pumping wells declines year by year, submersible pumps are recommended for heavy oil production. The application of submersible pumps in 25 well times showed that total production, previous production mode and geological characteristics were the main affecting factors. Both waterflood index curves and geological characteristics were taken into consideration. High-lift submersible pumps can maximize the potential of ultra-heavy oil.
