Product Specification/Models
A. Brief introduction
PAC is white or yellowish powder, which is non-toxic, odorless, and
solvable in water, with stable resistance to heat, salt and
bacteria. PAC is kind of high quality, low-viscosity cellulose
polymer with low molecular weight. Mud fluid with this PAC can
reduce fluid loss, with high inhibition and weather resistance. It
is popularly applied to oil drilling especially brine well
B. The characteristics of PACÂ
(1) suitable for any mud fluid of from freshwater to the saturated
brine.
(2) low-viscosity PAC can effectively reduce fluid loss, without
remarkably causing increase in system mucus, especially high solid
content system.Â
(3) high-viscosity PAC can make high volume of grout and can
significantly reduce fluid loss, particularly applicable to low
solid mud and solid-free saline mud.Â
(4) 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.
(5) excellent drilling mud and workover fluid mud are also
efficient fracturing fluids.
C. The application of PACÂ
1, 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.
2, PAC\'s application in workover fluid.Â
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.
3, PAC\'s application in fracturing fluid
Fracturing fluid made with PAC is resistant to 2% KCL solution
(required when preparing fracturing fluid). It features good
dissolvability and easy to use. It can be prepared on engineering
field and gum forming is fast, with strong ability of carrying
sand. If applied to the stratum of low osmotic pressure, its
fracturing effect is more remarkable.
