| 摘 要： | 塔里木盆地古近系、白垩系地层含膏、含盐，气显示活跃，固井难度大。在总结前期微膨胀胶乳防窜水泥浆体系固井失利原因的基础上，重点考虑地层岩性特征，以提高二界面胶结质量为目的，优选出微膨胀防窜盐水水泥浆体系。该体系具有API失水量小、SPN值小、水泥石强度大的特点，经现场应用，封固井段固井质量优良，表明该体系有广泛推广的前景。

| Abstract: | In Tarim basin, Paleogene and Cretaceous strata contain cream and salt with active gas show, cementing is difficult. Based on the summarization on cementing failure causes of anti-channeling slurry with slight expansion latex in early stage, the characteristics of stratum lithology are mainly considered. With the purpose of improving the quality of second interface cementation, the anti-channeling saltwater mud system is selected out. This mud system has the characteristics of small API fluid loss, small SPN value and high cement paste strength. The field application shows the good quality of cementation in cementing process. |
