hydroxypropyl Guar gum for water-base fracturing fluid of oil field

The advantages of hydroxypropyl guar gum powder:
1, the residue rate is low.
In the process of hydraulic fracturing, the residue rate is too high, which can affect the diversion ability of the bottom layer, and can not reach the purpose of the fracturing process.. Hydroxypropyl guar gum powder dissolved in highly fracturing, water insoluble residue, low rate, easy operation of diversion bottom.
2, high viscosity, with sand ability.
After fracturing fluid is injected underground, guar gum powder viscosity is too low, will cause proppant blockage at the wellhead, causing huge losses to the oil fields. Hydroxypropyl guar gum powder with high viscosity, sand carrying ability, can make the pipe work more smoothly.
3, strong heat resistance.
Guar gum powder in fracturing fluid in the decomposition speed can be accelerated with the increase of temperature, unable to achieve its function. Hydroxypropyl guar gum powder under high temperature decomposition speed slow, suitable for high temperature operation.
4, salt tolerance.
Guar gum powder and the viscosity will decrease with the extension of time, the longer the storage time, the lower the viscosity. Hydroxypropyl guar gum powder viscosity decreased very slowly, salt tolerance, strong adaptability.
