平顶山盐田采卤井生产套管固井技术研究

The Production Casing Cementing Technique for the Brine Well of Pingdingshan Salt

针对河南平顶山盐田地质特点及固井难点,在总结前期固井问题的基础上,通过开展有针对性的抗盐水泥浆体系、提高顶替效率、防漏固井配套施工工艺等的应用研究,解决平顶山盐田采卤井固井难题,确保固井第一界面、第二界面的胶结质量,水泥返到井口,形成固井配套技术,为平顶山盐田采卤井固井施工提供指导意见。

For the geological characteristics and the difficulty of the cementing of the Pingdingshan salt pan, on the basis of pre- cementing, by conducting targeted resistance to salt water mud system,this paper applied research to improve the displacement efficiency, mud loss construction technology supporting cementing to resolve the cementing problems of Pingdingshan salt pan brine well.Ensure the cementing quality between the first interface and the second interface, cement back to the wellhead, form cementing technology to provide guidance to Pingdingshan salt brine extraction well cementing.
