摘要
葡萄花油田属"三低"油田,随着油田注水开发的不断深入,欠注形势严峻、治理难度加大,截止2010年底欠注井数占总开井数的28.3%,急需开展有针对性的治理措施。本文创新性地提出了无支撑小型酸压技术,通过室内实验优选酸液配方,借鉴清水压裂及大型酸压工艺技术思路,利用常规泵车开展不填充支撑剂的小型酸压试验,探索欠注井层的低成本治理新途径。
Putaohua oil field is a ＂three low＂ oil.With the deepening of oil field water injection,under injection situation grim,increased the difficulty of treatment,by the end of 2010 the number of injection wells in total well number 28.3%,the urgent needs for targeted management measures.Puts forward innovative without supporting small acid fracturing technology,through laboratory experiment optimization of acidizing fluid formula,draw water fracturing and acid fracturing technology train of thought,by using the conventional pump development filled proppant small acid pressure test,exploration of injection wells in layers of low cost governs new approach.
