Detail
Capillary Suction Timer (CST)
Description:
The capillary absorption time tester measures the time required for the slurry composed of various test solutions and shale powder to penetrate a certain distance through the special filter paper. This value is called CST value. Its size is related to the properties of liquid, colloidal dispersion and other factors, and can be used to determine the colloidal dispersion degree of shale in water. The smaller CST value is, the better the inhibition effect is. The smaller CST value indicates: (1) small shale hydration effect; (2) Small colloidal dispersion; (3) Shale activity. The capillary absorption time tester can be used in many fields, such as sewage treatment (rapid testing of sludge filtration characteristics and status), testing and research of oilfield chemical treatment agents (evaluating the ability of mud to inhibit dispersion, the anti swelling ability of drilling fluid, the ability of drilling fluid to inhibit hydration and dispersion, and optimizing the formula of working fluid entering the well, such as the type, dosage and ratio of treatment agents, and can also be used as a new tool for analyzing and evaluating shale classification)
Structure and working principle of the instrument:
Composition: It includes a timer, stainless steel cylinder, test probe, etc. The diameter of one end of the stainless steel cylinder is 1 cm, and the diameter of the other end is 1.8 cm.
