| Abstract: | Based on requirements of cementing job in Jilin oilfield, Chemicals Corporation Limited in Weihui City of Henan Province made adjustment on G203, its original low density early strength additive. This paper introduces the adjusting procedure, and the modified product is named as G203(A). The influence of temperature on G203(A) 's performance was investigated on issues such as fluid loss control, compressive strength development and other properties. Test results showed G203(A) had good compatibility with other cement additives, the thickening time of the slurry with G203(A) in was shorted, and the early strength of cement stone was improved. Application of G203(A) in Yingtai, Qian'an and Nenzi Blocks verified its contribution to well cementing quality increase. |
