摘　　要：鲁克沁油田是一个深层稠油油田,进行常温注清水开发,取得了较好开发效果。但随着油田累计注入量增加,注水压力已接近地面系统压力,水井欠注日趋严重,采用常规酸化进行降压增注有效期短,经济性差。本文针对稠油水井堵塞机理研究,提出了生物解堵工艺,通过应用,效果显著,为稠油油田水井降压增注提供了一条新的技术思路,具有广阔的推广及应用前景。Lukqin oilfield is a deep heavy oil field,at room temperature with water injection development,achieving better development results.However,with the total injection volume of oil increased,pressure has been close to the ground water system pressure,injection wells due to the growing use of pressure dropping by injection of conventional acid for a short period have little profit.In this paper,from the study of the blocking mechanism of heavy oil wells,biological blocking solution process is proposed.Through the application,the results are significant,which provides a step-down new technical idea for havy oil wells with a broad promotion and application prospects.
