n: an acid that has been chemically treated before the acidizing or acid fracture of a well to lessen its corrosive effect on the tubular goods and yet maintain its effectiveness. See acid fracture, acidize.

n: pumping the liquid to the holebore, 1.)to provide the pressure head to controll the high pressure layer , the aim of that to help safty drilling. 2.) when acid fracture in oil layer, pumping the liquid followed the acid fracture liquid , it prevents the a

the fluid that is injected into a well.

n: pumping the liquid to the holebore, it provides the pressure head to controll the high pressure layer and prevents the acid fracture liquid from backward and enforce the liquid entering the manipulative layer.
