Cement paste suspension reinforcing agent and cement
The invention discloses a cement slurry suspension reinforcing agent and cement. The cement slurry suspension reinforcing agent comprises the following components: a suspension stabilizer, a low-temperature dry strength agent and a reinforcing agent. The invention relates to the technical field of oil field well drilling and cementing, in particular to a cement paste suspension reinforcing agent. By adding the suspension stabilizer, the low-temperature dry strength agent and the reinforcing agent, the liquid low-temperature low-density cement paste does not need strong shore-based support for cement mixing, does not need strong platform cement storage capacity, can solve deepwater surface layer well cementation operation far away from shore-based support, and can be directly charged on a platform, so that the operation is simple, and the cost is low. And the additive realizes full liquification, so that the timeliness is enhanced. Meanwhile, the settling stability of the slurry can be kept, the better enhancing effect is achieved, the stratum in the deepwater development well operation is not prone to fracture, and finally the problem that a floating bead low-density system is high in cost can be solved.
本发明公开了一种水泥浆悬浮增强剂以及水泥，包括以下组分：悬浮稳定剂、低温旱强剂以及增强剂。本发明涉及油田钻井固井技术领域，特别涉及一种水泥浆悬浮增强剂。本发明通过添加悬浮稳定剂、低温旱强剂以及增强剂使得液体低温低密度水泥浆无需强大的岸基支持进行混灰，无需强大的平台储灰能力，可以解决远离岸基支持的深水表层固井作业，全部可以在平台上进行直接加料操作，添加剂实现全液体化，增强时效性。同时既能保持浆体的沉降稳定性，还有较好的增强效果，使得深水开发井作业中的地层不易破裂，最终可解决漂珠低密度体系高成本的问题。
