Universal Additive to improve Properties of Aqueous cement paste to be used for Cementing a Reservoir and Method for converting the properties of an aqueous cement paste

摘要

A general additive used to improve the properties of cement slurries. One feature of cement cement used is that it contains a combination of ferric chloride in a group consisting of ferric chloride, ferric chloride and their mixtures, with a content between 0.5 and 30 parties. By weight: a halogenated alkaline metal or alkaline earth metal, between 5 hasta60 parts by weight; an organic acid, between 0.01 and 10 parts by weight;And an aqueous polymer in the range of 1 to 50 by weight. The way to convert the properties of deuna PAS underwater cement into a general additive is to use an over water cement slurry (including a hydraulic cement and water) to change the weight percentage of this over water cement from 0.1% to 30%. Aditi VO includes ferric chloride (ferric chloride, iron and their mixtures), a halogenated metal alkali alkali alkali alkali alkali alkali iron, an organic acid and a hydrate.
