Physical and Chemical Indexes of Sodium Carboxymethyl Cellulose for Drilling Fluid.(Perform SY5093-92 Standard)
Note:Perform OCMA NO.DFCP-2/NO.DFCP-7 Standard.
Product performance and characteristics:
1.CMC has a high ability to control water loss. In particular, PAC is a highly effective fluid loss reducer at lower dosages. You can control the loss of water to a higher level. It does not affect other properties of the mud.
2.The formed mud cake is of good quality, strong and tough.
3.It has good temperature resistance and excellent salt resistance. Under a certain salt concentration, it still has a good ability to reduce water loss and maintain a certain rheology. Compared to soluble in salt water and soluble in water, the viscosity hardly changes. Particularly suitable for offshore drilling and deep well requirements.
4.It can well control the rheological properties of the mud. It has good non-Newtonian fluidity.
5.In addition, KELAIDE® CMC is used as a cementing fluid to prevent fluids from entering pores and fractures. It is used as a fracturing fluid to control fluid loss into the well.
The company introduced a large-scale automated production line from Germany, specializing in the production of redispersible polymer powder, hydroxypropyl methyl cellulose, sodium carboxymethyl cellulose, and polycarboxylic acid water reducer.
