1.问题的提出对于油田供水、注水管道,采取水泥砂浆衬里(以下简称“衬里”)的办法,在一定程度上解决了内腐蚀问题。但是,随着油田的开发,供、注水和污水管道大量增加,考虑到节约能源和投资效果,研究和探讨“衬里”的经济性是必要的。目前,油田上对管道“衬里”的施工要求县:管道口径小于或等于150毫米者,砂 1. Issues raised For the oilfield water supply, water pipelines, the use of cement mortar lining (hereinafter referred to as “lining”) approach to a certain extent, to solve the problem of internal corrosion. However, as oilfield development, supply, injection and sewer pipelines have increased substantially, it is necessary to study and explore the economics of “linings” in view of energy savings and investment effects. Currently, the construction of the pipeline “lining” on the oilfield requires that the pipe diameter is less than or equal to 150 mm and the sand
