Polyanionic cellulose (PAC) is made of natural cellulose by chemical modification of water-soluble cellulose ethers derivatives, is a kind of important water-soluble cellulose ether, white or yellowish powder, non-toxic, tasteless, it can be dissolved in water, often using the sodium salt, widely used in oil drilling, especially in salt Wells and offshore oil drilling. Polyanionic cellulose has good heat stability, salt resistance and antibacterial activity.
The unique molecular structure of PAC makes it show excellent application performance in fresh water, salt water, sea water and saturated salt water. When used as fluid loss control agent in drilling fluid, PAC has efficient water loss control ability, and the mud cake formed is thin and tough. Used as viscosifier, it can quickly improve the apparent viscosity, plastic viscosity and dynamic shear force of drilling fluid, and can improve and control the rheology of mud well.
Belongs to ionic cellulose ether, with high purity, high degree of substitution, substituent distribution and other characteristics. It can be used as thickening agent, rheological regulator, water loss reducer, etc.
1)High degree of substitution, good uniformity of substitution, high viscosity, low dosage, effectively improve the use efficiency of mud;
2)Good moisture resistance, salt resistance, alkali resistance, suitable for fresh water, sea water, saturated salt water based mud;
3)The mud cake formed is of good quality and stable, which can effectively stabilize the soft soil structure and prevent the collapse of the shaft wall.
4)It is suitable for mud system where solid content is difficult to control and varies widely.
