G级油井水泥石的溶蚀性研究
Corrosion Study of G-grade Cementstone in Oil Wells
-
摘要: 用化学方法解除油管内的水泥窑可以减少机械方法施工时的困难,以及对开眼的破坏性。文内通过室内对水泥石的溶蚀试验,评价部分无机酸在不同浓度下对油井G级水泥石溶蚀能力,并探索了提高溶蚀速度的方法。Abstract: Removing cement plug in oilpipes with chemical methods can reduce difficulty of mechanical operation and damage of wellbore. Corrosivity of sevcral inorganic acid to G-grade cementstone in oil wells are evaluated through laboratory cementstone corrosion experiments and ways to raise corrosion rate are also studied.
