摘要

摘要: 为了研究一种对AMPS水泥浆体系有效的低温促凝剂,对不同组分促凝材料促凝效果进行了研究。采用正交实验,优选出了一种可以在AMPS水泥浆体系中起到良好促凝效果的促凝剂BCA-210S。结果表明,该促凝剂能促进AMPS油井水泥低温水化能力,缩短其在低温下的稠化时间,能将稠化时间控制在60 min左右;使静胶凝强度过渡时间降低到10min;在30℃、8 h条件下抗压强度可达到5.3 MPa。结论认为,该促凝剂能显著提高水泥石早期抗压强度,表现出优异的低温早强、防窜性能,有助于解决低温井、调整井固井面临的问题,是一种新型多功能促凝剂。

Abstract: A study on the acceleration performance of different accelerators was conducted to try to find an effective low temperature accelerator for the AMPS cement slurry. A high performance accelerator BCA-210S that can be used in AMPS cement slurry was selected using orthogonal experiment method. BCA-210S has the ability to promote the hydration of AMPS cement and to shorten the time for cement slurry to thicken at low temperatures. Using BCA-210S, time required for cement slurry to thicken at low temperatures can be controlled to about 60 min, transit time required for the gel strength of cement slurry reduced to 10 min, and compressive strength of set cement under 30℃ increased to 5.3 MPa after 8 h. It is concluded that BCA-210S increases the early compressive strength of set cement, which in turn exhibits excellent low temperature early strength and anti-channeling performances. As a new multi-function accelerator, BCA-210S is beneficial to solving problems encountered in cementing low temperature wells and adjustment wells.
