七十年代以来,水泥护壁堵漏技术,无论国内或国外都得到较大的发展.发展的标志是:1.能满足不同条件下护堵用的水泥新品种不断增加;2.改善水泥浆及其凝固体的物理力学性能的添加剂日趋完备;3.水泥浆性能测定从静态试验过渡到模拟孔内条件的动态试验,新型的测试仪器不断出现;4.水泥的灌注技术水平有较大的提高,工艺渐趋完善;5.水泥灌注的基础理论研究有一定进 Seventies, cement wall plugging technology, both at home and abroad have been greater development. The signs of development are: 1. Can meet the different conditions of retaining the use of new varieties of cement to increase; 2. To improve the slurry and The solidification of the physical and mechanical properties of additives increasingly sophisticated; 3. Determination of the performance of cement slurry from the static transition to the dynamic simulation of the conditions of the hole test, a new type of testing instruments continue to emerge; 4. The level of cement infusion technology has been greatly improved , The process is gradually improving; 5. The basic theory of cement infusion has some progress
