Capillary Suction Timer

Capillary Suction Timer

Description:

The capillary absorption time analyzer measures the time required for various test solutions and shale powder slurries to permeate a certain distance through specially designed filter paper. This value is called the CST value. Its size is related to factors such as the properties of the liquid and the dispersibility of colloids, and can be used to determine the degree of colloidal dispersion of shale in water.

The capillary absorption time analyzer can be used in multiple 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, anti swelling ability of drilling fluid, inhibition of hydration dispersion ability of drilling fluid, optimizing the formula of the working fluid entering the well, such as the type, dosage, and ratio of treatment agents, etc. It can also be used as a new method for analyzing and evaluating shale classification).

Structure and working principle of the instrument:

Composition: Includes timer, stainless steel cylinder, test probe, etc. The stainless steel cylinder has a diameter of 1 centimeter at one end and 1.8 centimeters at the other end.

The smaller the CST value, the better the inhibitory effect, and its minimum value indicates that:

1. The minimum shale hydration effect; 2. Minimum colloidal dispersion; The lowest shale activity is 3.
