CH610 is a high temperature polymer retarder independently developed by Kelioil, which is applicable to high temperature deep wells below 302°F (150℃).
Compared with compound retarders such as glucose and phosphate, it has the following outstanding advantages:
Its thickening time shows a linear relationship with the dosage,and the dosage is insensitive with good adjustability.
The mutation value of the high-temperature thickening curve is small, and it is less likely to have defects such as bulges and steps.
Kelioil has many years of experience. The professional R & D team deeply explores the formula, advanced testing ensures the quality, the production process is mature, and strict control is carried out from raw materials to finished products, committed to providing you with stable and reliable retarder products.
