摘要
盐膏层储层固井往往存在井漏、井喷及卡钻事故,如何构建一套适用于含盐储层固井封隔的水泥浆配方体系及配套施工工艺一直是各大油田争相探讨的重难点所在。本文就盐膏层所存在的固井难点、盐层蠕动机理以及具体的防治措施进行了分类研究,旨在提高对盐膏层固井的进一步认识。
Many accidents including lost circulation,blowout and sticking often occur in the well cementing of salt gypsum reservoir.How to build a set of slurry formulation system and supporting construction technology suitable for the cementing and sealing of salt reservoir has always been the key and difficult point for the major oil fields.In this paper,these difficulties were classified and studied,peristalsis mechanism of the salt gypsum layer was analyzed,and specific prevention and control measures were put forward in order to improve the further understanding of the well cementation of the salt gypsum layer.
