Acidification is one of the main measures to increase oil and gas production. Acidification can restore or improve the permeability of formation pores and cracks by using the principle that acid dissolves and decomposes rock cements, formation pores, and cracks. The addition of acidification thickener can increase the viscosity of the acid, reduce the diffusion rate of the acid, increase the acid action distance, shorten the time for the acid to reach the rock formation, increase the width of the acid, improve the acidification effect, and achieve the purpose of improving the permeability of the formation.

The acidification thickener produced by Noel Group is a homopolymer cationic polymer, a white amorphous powder, with the characteristics of fast polymerization rate, large molecular weight, fast dissolution rate, high temperature resistance, shear resistance, and degradation resistance.
