针对油水井出现水淹层、油气枯竭层、套管损坏、套管外窜通等问题,常利用液体压力挤压灰浆使之进入地层缝隙或多孔地层,或是利用液体输送灰浆在井筒套管内留一定长度的灰浆柱,从而实现封堵封窜。纯梁采油厂经过近年来不断探索,解剖分析每次施工,在优选封堵材料,拓展封堵技术,优化封堵方式方面,总结形成了一定的工作思路,从而达到灰浆封堵封窜施工规范化,收到了很好的应用效果。
Aiming at the problems of water flooding layer, oil and gas depletion layer, casing damage and casing outside channeling, etc., often use liquid pressure to squeeze mortar into the formation gap or porous formation or use liquid delivery mortar in the well casing Leave a certain length of the mortar column, in order to achieve blocking seal channeling. After years of exploration and anatomical analysis of pure beam oil production plant, we conclude a certain work train of thought in terms of optimizing sealing materials, expanding sealing technology and optimizing sealing methods so as to achieve the standardization of sealing and sealing of mortar , Received a very good application effect.
