高温大温差固井水泥浆体系研究
摘要
Abstract
Aiming at the cementing problem of the slow development of cement compressive strength at the top of a long cement column and gas migration in long cementing segment of high temperature deep well with large temperature difference. Based on the analysis of the slurry design challenges, a new strength regulator FZ-1 is developed through the rational design of cement addition composition, optimization of cement additive with good high temperature resistance performance and less impact on the compressive strength to accelerate the development of compressive strength. In this paper, a large temperature difference cement slurry system (1.90 g/cm3) is designed to solve ultra-retardation at the top of the cement column in large temperature difference cementing. Experimental results show that the cement slurry has the characteristics of good kinetic stability, low fluid loss, good rheology, easy to adjust thickening time and high compressive strength, and good anti-channeling ability to meet the cementing requirements for large temperature difference with BHCT of 110-140 ℃. And temperature difference of 50-70 ℃.关键词
