• Detailed Description:

  Cas No. :1327-41-9 A. BRIEF DESCRIPTION
  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 PAC
  * (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.
  * (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.
  * (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 PAC
  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.
  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.
