PAC LV
1.Sodium Carboxymethyl Cellulose(CMC) for Oil drilling IndustryPolyanionic cellulose,Website:http://www.s-cmc.com, PAC is easy soluble in water, having excellent properties of salt-resistance, Calcium,Magnesium-resistance and reduce filtration loss. It can be used in different drilling/completion drilling fluids, especially in salt water based drilling fluids, seawater based drilling fluids and saturated-brine drilling fluids,can reduce filtration very well.?Polyanionic cellulose Low Viscosity(PAC-LV)can be used in different drilling/completion drilling fluids, especially in salt water based drilling fluids, seawater based drilling fluids and saturated-brine drilling fluids, can reduce filtration very well. Because PAC having a very good solubility in water, excellent performance of salt-resistance and reduce filtration loss.2. Commodity Name: Polyanionic celluloseCAS No.: ?9004-32-4?E No.: ?E466?Molecular formula :?C6H7O2(OH)2OCH2COONa?nSynonyms: PAC,PAC HV,PAC LV,PAC R, Polyanionic celluloseHS Code: 391231003. Description?YUYU? Introduction to Oil Drilling PAC??YUYU? PAC oilfield grade is divided into LV and HV(HV)?Slurry with PAC would form thin but hard filter cake with low permeability, reducing water loss. Adding PAC into slurry will endow the drill with low initial gel strength, making the slurry give off the gas inside and abandoning the waste into the slurry pit. Same as other suspending dispersion, the drill slurry has an existing period which will be stable and extended after adding PAC.Slurry with PAC is seldom affected by the bacterium and requires no high PH value or corrosion resistant.Slurry with PAC has excellent stability and will still reduce the filtration loss under 150? or above.4. Type and Specifications1)LV PACProduct type& quality specification (standard: GB/T 5005-2010 and API 13A)2.jpg2)HV PACProduct type& quality specification (standard: GB/T 5005-2010 and API 13A)3.jpg3)Common PACProduct type& quality specifcationRemarks: samples of different specifications are available according to customer requirements5. Properties1) ? ? ?Evenly substituted, high transparency, control viscosity and reduce filtration loss2) ? ? ?Applied in fresh water,seawater and brine water based mud system3) ? ? ?Formulated mud show good filtration loss, brine-resistance and high temperature stable4) ? ? ?Formulated mud show good rheology control,to inhibit clay or shale swell or collapse, hence to prevent well contamination5) ? ? ?Stable soft soil structure, prevent well collapse6) ? ? ?While drilling through the rock surface, to slow down the solid accumulation in mud.7) ? ? ?Keep down the turbulence scale,to minimize the pressure loss in reverse-flow system.8) ? ? ?Improve mud yield, reduce filtration loss9) ? ? ?Stable foam in mud6. AdvantagesWidely available and low cost polymer for fluid Loss control.It is an effective at providing filtration control in most water based drilling fluids.?It is effective in low concentrations.It is Non?Toxic.?It is not subjected to bacterial fermentation and calcium contamination.?Can be sed Fluid systems.7. PackagePacking:25kg kraft paper bag, or other packing as clients request.8. Storage1.Store in a cool, dry, clean, ventilated environment.2. Material must be handled as a Industrial chemical, wearing protective equipment and observing the precautions as mentioned in the MSDS.3.
