Sell Sodium Carboxymethyl Cellulose CMC-HVT

详情

1. Introduction
   CMC can reduce water loss, and increase viscosity in drilling fluid, cementing fluid and fracturing fluid. They play the roles of protecting the wall of well, taking drilling trifles, protecting drilling bit, preventing mud loss and increasing drilling rate.It is widely applied in various waterbased drill fluid systems, having a good suspension effect,emulsion stability and fluid loss effect as well.The mud cake formed is smooth and tough.

2. Technical indext(Performance standard: API)
 

Item				Index
Starch or starch derivative				N/A
Deionized water solution				≥*0		Solution viscometer with reading value **0r/min
*0g/L salt water solution				≥*0		Solution viscometer with reading value **0r/min
Saturated salt water solution				≥*0		Solution viscometer with reading value **0r/min
Suspension filtration, m/L				≤*0

3. Usage and use method
  3.1 Able to be used for protection of oil well as mud stability and water retaining agent in oil drilling.
  3.2 CMC series have a good fluid loss effect, the mud containing CMC enables the shaft wall to form thin tough mud cake with low permeability which can reduce the filtration loss and resist salt to saturation.
  3.3 CMC series can resist temperture to **0°C to **0°C, and the temperature resistance can be improved with the use of antioxidant.
