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。
The chemical removal of cement kilns from tubing can reduce the difficulties of mechanical methods of construction and the destructiveness of the open eyes. In this paper, the dissolution test of cement stone indoors was conducted to evaluate the corrosion resistance of some mineral acids to G grade cement stone of oil well at different concentrations, and the method to improve the dissolution rate was explored.
