The JK-SR fracturing fluid system effectively addresses the challenge of swift dissolution and adhesion of thickeners during the continuous mixing stages in large-scale fracturing operations within horizontal wells. Pioneering technologies, notably cross-linking, have substantially enhanced the efficiency of fracturing processes and concurrently minimized associated costs.
This immediate fracturing fluid system encompasses a comprehensive range of five key products: instant guar gum FHG, cross-linking agent JK-JL, drainage aid JK-ZP, clay stabilizer JK-FP, and fungicide JK-SJ.
