摘要
研究了G级油井水泥及掺入外加剂时水泥浆滤液的离子成份和含量。考察了水泥浆滤液与地层水和泥浆滤液的配伍性。通过对含有外加剂水泥浆滤液组成的分析,提出了一种减少滤液中的有害离子(Ca^(++),Mg^(++),SO_4^-,OH^-等)浓度的新途径。
This paper studied the chemical composition of the cement filtrate in the slurry with or without additives, tested the compatibility of mud—cement and formation brine—cement. Based on the analysis of cement filtrates with different additives, a new way to reduce the damaging ion concentration in cement filtrates is to use the additive which has ho poisoning to the nucleation process of calcium hydroxide, weigh can Iower formation damage caused by cement filtrates.
