Pre-crosslinking Swellable agent

The characteristics: 

Accepting the couplet of particle profile control agent for sage green or brown solid particles and powder mixture, this product can be used for water well profile control and water plugging. 

1. the water swell, and crosslinking agent, used in combination with coagulant, generate high viscosity gel plugging agent 
2. good adhesion, when using, can carry a variety of solid proppant (such as carbon calcium powder, bentonite, etc.) to increase strength of plugging agent, plugging in the borehole is not embolism; 
3. no special requirements for water, tap water, recycling water, ground water can be used, without acid to adjust PH value, belongs to the scope of neutral, no corrosion of equipment, pipeline and good adaptability of strata; 
4. adjustable gel time, gel viscosity high, intensity big, 10 mp pressure plugging agent don't spit, and can be blocked, don't pollution after plugging formation; 
5. gel speed can be controlled by crosslinking agent amount, gel time 4 hours to 3 days, can realize the large dose of depth profile control of injection Wells; 
6. the greater the depth profile control and injection water is, the greater the effect is better, the longer the period of validity, water or oil displacement agent channeling flow also is less, the better, to determine the gel time reduced, most to gel into the shaft segment can be adjusted for rapid gel, in injection Wells, to seal the well can be well open a week production; 
7. use temperature scope (20-120), thermal stability, non-toxic, easy preparation is not affected by seasonal temperature, all the year round all can construction, the construction can be adopted when the shaft or stratified water plugging.
