针对吉林油田固井设计施工需要,河南省卫辉市化工有限公司对原有的G203进行了调整。本文介绍了低密早强剂G203(A)的调整方法,考察了温度对G203(A)性能发挥的影响,并评价了G203(A)对水泥浆失水、抗压强度及综合性能的影响。评价结果表明。调整后的低密早强剂G203(A)与其他添加剂配伍性好,能够提高早期强度缩短候凝时间,固井成本低。在吉林油田新开发的英台、乾安和嫩字地区的固井施工中,效果良好,表明该早强剂有一定的市场应用前景。
In response to the cementing design and construction needs of Jilin Oilfield, Weihui Chemical Co., Ltd. of Henan Province adjusted the original G203. This paper introduces the adjustment method of G203 (A), investigates the effect of temperature on the performance of G203 (A), and evaluates the effect of G203 (A) on water loss, compressive strength and overall performance of cement slurry . Evaluation results show. Adjusted low-density early strength agent G203 (A) compatibility with other additives is good, can improve early strength to shorten the waiting time, low cementing costs. In the new development of Jilin Oilfield Yingtai, Qianan and tender words in the cementing construction, the effect is good, indicating that the early strength agent has a certain market prospects.
