Mutual solvent

Product Description
Mutual solvent is a kind of acidizing operation assistant agent developed and prepared according to requirement for construction process of oilfield acidizing. It can reduce the absorption loss of surface active agent and enable easy combination of fluid drops formed during the acidizing process. It can prevent emulsification of oil water, accelerate backflow, keep wettability of rocks, recover or improve oleic phase permeability. In addition, it has functions of cleaning reservoir layer, eliminating organic plugging materials and improving acid treatment effect. It has good compatibility to enable each kind of acidizing agents to play collaborative functions to improve efficiency of acidizing fluid and realize the yield increase.
