Abstract

One important reason why it is hard to ensure quality of high-temperature deep well cementation is that it is hard to ensure the comprehensive performances of cement paste at a high temperature. So far, in most cases, admixtures are used to adjust the high-temperature performances of cement paste, and such admixtures are dominated by polymers. At a relatively high temperature, the settlement stability and fluid loss of cement paste are regulated by fluid loss agent, and thickening time is regulated by retarder. The deeper the well is, the higher the temperature and pressure at the well bottom will be. It is hard to regulate the settlement stability, fluid loss and thickening time of cement paste at a high temperature. Therefore, it is hereby to recommend an assessment method for heat resistance of polymer admixture, to facilitate the optimal selection of polymer admixture.
