Study on Cement Slurry System for Deep and Ultra-Deep Wells

GAO Kai

Abstract


Cementing quality can’t meet the requirements in deep and ultra-deep wells cementing because of many factors such as long open hole section, multiple pressure system, high temperature and high pressure. In order to solve the problem of cementing in deep and ultra-deep wells, retarder and fluid loss additive were studied, then the cement slurry system for deep and ultra-deep wells were developed and the performance was evaluated. The results show that the cement slurry has steady performance for high temperature, adjustable thickening time, less fluid loss, good settlement stability, and high compressive strength, all of which can meet the requirement of cementing in deep and ultra-deep wells. Pilot tests of this cement system were conducted in more than 30 wells in Shengli, Dagang, Liaohe, Jiangsu, Jilin and Offshore oilfield, cementing qualities of these wells were qualified, which indicates that comprehensive performance of this kind of cement slurry system can meet the technical requirements for deep and ultra-deep wells cementing, which provides the references for the deep and ultra-deep wells cementing in all of the word.
