PAC polyanionic cellulose is a high-purity refined product with a white flowing powder appearance, and its aqueous solution is a transparent viscous liquid. Polyanionic cellulose is a water-soluble polymer, which can be used as a thickener, rheology control agent, binder, stabilizer, protective colloid, suspending agent, and water retention agent.
In the oil drilling industry, poly anionic cellulose is a better drilling mud treatment agent and material for preparing drilling fluids. It has a high pulping rate and good salt resistance. For light cement slurry, sea cement slurry and saturated salt cement slurry, oil drilling grade poly anionic cellulose is an excellent fluid loss treatment agent and has a good viscosity lifting ability and high-temperature resistance (150 ℃) ability. Besides, it can also be added with calcium chloride to formulate into drilling fluids of various densities so that the drilling fluids still have a certain viscosity and a low fluid loss.
Kingsun polyanionic cellulose is an anionic cellulose ether with high purity, a high degree of substitution, and uniform distribution of substitution. High-viscosity and low-viscosity PAC have excellent fluid loss reduction in freshwater and sea cement slurries and they are indispensable products in mud compatibility. Kingsun polyanionic cellulose (PAC) products are exported to many countries and regions in the world, they have excellent product performance and reliable quality.
Kingsun PAC-HV and PAC-LV can reach the European OCMA standard and the American Petroleum Institute API 13A standard.
Oil drilling grade PAC
The mud fluid prepared by Kingsun polyanionic cellulose (PAC-HV, PAC-LV) has a good fluid loss, inhibition ability, high-temperature resistance, and salt resistance. Its pulping rate in freshwater, 4% brine, and saturated brine are high. It is widely used in oil drilling, especially for deep wells, high-temperature wells, brine wells, and offshore oil drilling.
■ Suitable for any mud from freshwater to saturated brine.
■ High pulping rate. PAC polyanionic cellulose pulping capacity can reach 2-3 times of ordinary CMC.
■ PAC-LV can effectively reduce fluid loss. PAC-HV has a high pulping capacity, and has an obvious effect of reducing fluid loss.
■ Mud fluid can inhibit the dispersion and expansion of clay and shale in high-salt media so that the pollution of the good wall is controlled, and the time of clay hydration, expansion and dispersion is delayed.
■ Good ability to protect colloid.
■ PAC polyanionic cellulose can be used in many complex formations and difficult drilling conditions such as ocean and desert.
It is ideal to use PAC powder as an inhibitor and fluid loss agent in drilling fluids. The mud fluid formulated by Kingsun PAC polymer can inhibit the dispersion and expansion of clay and shale in a high-saline medium, thereby controlling well wall pollution.
In the workover fluid, the workover fluid prepared by polyanionic cellulose is of the low solid phase, so as not to block the permeability of the production layer due to solids, and will not damage the production layer. And it has low water loss, which reduces the amount of water entering the production layer. Workover fluids formulated with poly-anionic cellulose provide advantages not found in other workover fluids:
■ Protect the production layer from permanent damage;
■ It has the carrying capacity to clean the wellbore, and the workload of maintaining the wellbore is reduced;
■ It has the ability to resist the infiltration of water and sediment;
■ It can be stored or transferred from well to well, which is lower in cost than ordinary mud workover fluid.
The fracturing fluid prepared with PAC in fracturing fluid can withstand 2% KCI solution (must be added when preparing fracturing fluid) and has good dissolution performance, easy to use, can be prepared on-site, and has a fast gel-forming speed and strong sand carrying capacity. Used in low osmotic pressure formations, the fracturing effect is more outstanding.
