Polyanionic Cellulose Application:
PAC's application in drilling fluid : PAC used as inhibitor and filtration reducer is very good, and fluid mud made with PAC can inhibit dispersion and expansion of clay and shale in high-salt media so that sidewall pollution of drill can be controlled. Compared with CMC, PAC has better uniformity of response, with higher degree of substitution, better transparency and excellent resistance to salt and heat. It can create high-volume mud and cause low-volume loss, according to the test of OCMA.
PAC's application in workover fluid:Workover fluid made with PAC is of low solid so that the infiltration capacity of productive zone can be avoided being blocked, and productive zone can be protected. More, because of its low water loss, PAC workover fluid can reduce water that goes into productive zone, and the water that enters into productive zone will cause a water township phenomenon resulted from the blocking of emulsion. PAC workover fluid provides more benefits than any other same products do: prevent productive zone from being permanently damaged; clean drill hole and reduce maintenance to drill hole; block filtration of water and mud and cause less bubbling; store or can be used from one well to another, with lower cost than that of any other same products.
