The action of chlorinated potassium in CBM well fracturing operation
In fracturing operation in oil field,KCl serves as main clay stabilizer mixed in fracturing fluid.The experiment indicated,that KCl mixed in CBM well fracturing fluid plays not only as antisweling agent,but it can also change adsorption properties and water wetability of coal matrix,resulted in increasing back-discharge rate of reservoir and decreasing reservoir damage.
