Hand Operated Centrifuge HSHD-1602

The purpose of using potassium ions in drilling fluid is to stabilize shale and suppress expansive clay. Therefore, it is necessary to accurately determine the content of potassium ions in order to control the performance of drilling fluids. Model HSHD-1602 Hand Operated Centrifuge is used to determine the potassium ion content of drilling fluid filtrate when the potassium ion concentration is higher than 5000mg/1 or the KCl concentration is higher than 3.5lb/bbl. After precipitating potassium ions with perchlorate in a centrifuge tube, measure the volume of the precipitate and read the potassium ion content from the standard curve.

Overview

The purpose of using potassium ions in drilling fluids is to stabilize shale and inhibit swelling clays. Therefore, the potassium ion concentration must be accurately determined in order to control the performance of the drilling fluid. This hand-cranked centrifuge is used to determine the potassium ion content in drilling fluid filtrates when the potassium ion concentration exceeds 5,000 mg/L or the KCl concentration exceeds 3.5 lb/bbl. After precipitating the potassium ions with perchlorate in the centrifuge tube, the volume of the precipitate is measured, and the potassium ion content is read from a standard calibration curve.
