        PAC and CMC are used in oil drilling fluids and completion fluids. In drilling fluids, it works as viscosifier, flowing controller and filtration reducer, with strong suspending capability, high ability of carrying crumbs, and the function of cleaning drilling crumbs, stabilizing of well wall, preventing the mud from flowing away, protecting drilling bit and reducing the thickness of mud cake, but while in the completion fluids, it functions to control the fluid viscosity, suspend the heavy objects, bring the filler and avoid the fluids loss. It also can replace guar gum in fracturing fluids. 

        Our PAC (oil drilling grade) and CMC are advantageous because of their: small usage, high yield; good salt tolerance, anti-bacterial property and convenient to use; the fluid loss reduction and the viscosity improvement; flowing control and strong suspending capability; environmental friendly, nontoxic, harmless and odorless; and good liquidity, convenient to construction. 

        1、Application in Oil Drilling Fluids
        *Non-dispersive System
        Strong capability of carrying crumbs, restraining the dispersion of the clay, reducing the speed of pulp yield by clay, stabilizing the well wall and effectively increasing the drilling rate.
        *Dispersive System
        Good suspending capability, containing more solid phases, greatly increasing the stability of granule; best for configuring the high density drilling fluids, and adjusting the rheology of drilling fluids; forming the compact high quality mud cake in the drilling fluids. It has the good function of reducing the fluids loss and free water. 
        *Calcium treatment drilling fluids
        Good ability of calcium resistance, preventing clay granule which caused by calcium ion from excessive flocculation and make the drilling fluids stay into the flocculation conditions and maintain its stable solid content and rheology, so that the drilling fluids have the good and stable performance accordingly.
        *Salt water drilling fluids, sea water drilling fluids, and saturated brine drilling fluids
        Low sensitive to salt, and strong ability resistance in salt, calcium and magnesium, and it worked as rheologic modifier. Fast adjust the drilling fluid rheology in the low dosage conditions. Meanwhile, it can fast carry out the drilling crumbs and maintain the lower solid content, and enhance the speed of the well drilling rate. Used as filtrate reducer will form the compact mud cake, and due to the filter liquor filtrated by filter cake is very close to the earth layer primitive water, so it is less damage to the oil and gas layer. 
        *Potassium Base Drilling Fluids
        Low sensitive to sylvite, calcium salt and magnesium salt; fast and high efficiently adjust the rheology of drilling fluid. Besides the good effect in fluid loss reduction, it has the power of cleaning drilling crumbs and drilling bit, furthermore, it has the obvious effect in easily blocked drilling bit in earth layer. 
        *Polymer Drilling Fluids
        Good compatibility with other polymer, strong suspending power, cleaning drilling crumbs fast and efficiently, making the drilling fluids stay into low solid phase and low dispersion of clay, and it is also the good filtration reducer. 
        *Low Solid Phase Drilling Fluids
        Adjusting the rheology of drilling fluids fast and efficiently, excellent suspending power, cleaning drilling crumbs promptly and efficiently, maintaining the low solid content, enhancing the speed of the drilling rate, stabilizing the well wall, and possessing the good effect in filtration reducer.
        *Environment Friendly Drilling Fluids
        This products, with environment friendly, nontoxic, harmless and odorless, biodegradable property, cannot be rotten easily in service. Due to the low maintenance cost of drilling fluids, the constructors’ health and safety are guaranteed. It meets the demand of the kinds complicated geological conditions and no harm to agricultural production.

        2、Application in Completion Fluids
        *Improve the fluidity of the cementing liquids, and make the suitable initial adhesion with lower filtration loss, while it can protect the well wall and prevent the liquids from flowing into the pores and cracks. 
        * packed fluid
        Adjust the fluidity, thixotropy and suspended solid of the liquids. Due to the good salt tolerance property (especially the one Valence metal ion), the effect is obvious when the products are used in packed fluid of clean brine.
        * fracturing fluid
        Enhance the viscosity of fracturing fluids quickly, bring the proppant into the oil well cracks, build the infiltration lane, reduce the fluid loss quickly and make the formation pressure increase fast to reach the effect of transferring the pressure. No residue, no harm to the base and it can replace guar gum. 
        PAC-HVC is mainly used in cleaning fracturing fluids. Using Low dosage, reducing the fracturing fluids loss and possessing the good property of salt resistance and temperature resistance. Good water solubility, no residue, no harm to the base, high pumpability, high friction, and power to bring with proppant. 

        3、Special Function Products
        *Granulation Products
        Improve the work conditions, reduce the dust, dissolve fast and enhance the construction efficiency.
        *Instant Products
        It can be dispersed and dissolved quickly in water, and it is more convenient and simple when used in rugged drilling environment. 
        Higher efficiency in cement slurry configuration and low requirement for construction equipment.
        *The products in Special Applications
        When in the complicated conditions with small usage, the filtration reduction property is of more excellence .

        1、CMC-containing mud can make the borehole wall form thin and hard filter cake with low permeability and reduce water loss. When CMC is added to the mud, the drilling rig can get low initial shear force, which makes the mud easy to release the gas wrapped in it, and the debris can be quickly discarded in the mud pit.
        2、Drilling mud, like other suspended dispersions, has a certain shelf life, which can be stabilized and prolonged by adding CMC.
        3、Mud containing CMC is seldom affected by fungi, does not need to maintain a high PH value, and does not need to use preservatives.
        4、The slurry containing CMC has good stability and can reduce water loss even if the temperature is above 150 degrees.
