Research Of High Temperature Tolerance Latex Slurry System

摘要

This article presents a high performance latex material. By the studiesrnof the stability behavior of different latex slurries, a suitable latex isrndeveloped. Matched with the relative cement additives, this kind ofrnlatex slurry shows better performances in high temperaturernenvironments such as lower fluid loss, adjustable thickening time,rnquick strength development, anti-gas migration and good resistancernability. The slurry formulations and its set cement performances arernalso studied . Moreover, the applications of the latex cement slurries inrnsome high temperature wells are described.
