PRODUCT DESCRIPTION
The present invention is a thickening agent in order to solve the higher water-insoluble content, thickening ability is not strong, salt tolerance, shear resistance and temperature resistance undesirable problems of the prior art to provide gender ionic polymer water-based fracturing fluid thickener; Another object is to provide a method for preparing the water-based zwitterionic polymer fracturing fluid thickener.
APPLICATION METHOD
In the 20 ~ 28% HCL acid, after mixed with various additives, add 8 to 10% volume of thickening agent mixing. Then the acid according to the construction design pressure or acidification.
