PKN device intended to determine the coefficient of swelling clays. During the development of deposits of clay can change its volume and thereby significantly affect the recovery. Clay productive reservoirs in the mostly composed of kaolinite, montmorillonite and hydromica minerals, which have different swelling. One of the important requirements for the reagent used for injection to increase recovery is the reduction of swelling clays or completely prevent it. To determine the swelling of the clay used a special device KNP-2. Specifications: Corrosion-resistant housing. Scale indicator: 0.01 mm Working stroke indicator: 11.5 mm Overall dimensions: 65h85h415 Weight, kg: 0.7 Products supplied include: device KNP-2 manual.
