摘要:

随着矿渣MTC技术的发展和应用,矿渣MTC胶结物的抗腐蚀性能日益受到人们的关注。矿渣MTC胶结物的抗腐蚀性能直接关系到矿渣胶结物后期性能,并影响井和套管的使用寿命。分析了矿渣MTC胶结物可能受到的几种腐蚀类型及其机理,实验验证了矿渣胶结物具有较强的抗NaCl、Na2CO3、Na2SO4、MgSO4侵蚀的能力,但易受酸性介质腐蚀;实验发现了加入胶乳能较大幅度提高矿渣胶结物抗酸性介质腐蚀的能力,并对胶乳提高矿渣胶结物抗酸蚀能力的原因进行了分析。

Abstract:

With the development of mud changing to cement (MTC) technology, more attention is given to erosion of MTC slag block. In this paper, several probably erosion situation and mechanism of slag block are discussed. Laboratory testing results have showed that the slag block can resist erosion from NaCl、Na2CO3、Na2SO4 and MgSO4, but it is more likely corroded in acid medium such as NaHCO3solution. Many experiments are done in order to improve the resisting acid erosion capability of slag block. An effective way has been found that the resistant erosion capability in acid can be greatly enhanced by adding latex (10-15 percent of volume of mud) to slag slurry.
