Application of QUANSEN HPAM in drilling mud

Different concentration of polyacrylamide and its wall protection

Polyacrylamide is commonly used between 200 and 1000 ppm. At lower concentrations, polyacrylamide, for example 70-120ppm, has a certain ability to prevent collapse and protect the pores.The higher the concentration, the better the anti-collapse hole protection effect, and the better the mud stability and lubricity.

HPAM with a certain degree of hydrolysis was mainly flocculated at a low concentration (below 400PPm), and also had the effect of stabilizing the properties you added and the pore wall under certain conditions.When HPAM concentration was above 500PPm, the main function was stabilization and flocculation.


Drilling mud

Drilling mud is a mixture of water, bentonite (or clay) and additives.In the process of drilling pile construction, the pressure difference between mud and groundwater is used to control water pressure during mud circulation, so that mud can form mud skin on hole wall to reinforce hole wall and prevent collapse, and at the same time stabilize the water level in hole.At the same time, the mud also has the function of taking out the rock and soil debris, cooling and lubricating the drill bit.Therefore, whether in the pore-forming stage or the perfusion stage, it has an important influence on the pile quality, thus greatly affecting the bearing capacity of the pile foundation.


Fender mud refers to the mud formed on the hole wall to reinforce the hole wall and prevent the collapse, and at the same time stabilize the water level in the hole.


Drilling mud has many functions, but the most basic ones are as follows:

1. Carry drill cuttings to the ground.

2. Static and liquid column pressure balances the formation pressure to avoid blowout and collapse.

3. Hydraulic jet rock breaking.

4. Cooling the drill.

5. Filter cake is formed on the well wall to reduce fluid leakage to the formation, stabilize the well wall and reduce formation pollution.

Selection of drilling mud PAM

There are many types of drilling mud, and polymer polyacrylamide can be used as flocculant. Adjust the mud density and viscosity and water loss, so that the well drilling smoothly. 

According to the field application of quansen products, the anionic products with super high molecular weight are better used in drilling mud, and can be recycled.Good effect, low dosage and low cost.
