Material Description
Polyacrylonitrile is hydrolyzed to produce high molecular weight ammonium salt powder, which contains active functional groups such as ammonium carboxylate and amide. Ammonium ions can act on shale lattice, adsorb clay particles, optimize mud cake structure, and stabilize water-based drilling fluid colloid system.
 
Core selling point
1. Outstanding filtration reduction effect, improving the density of mud cake
2. Ammonium ions inhibit shale hydration and have the ability to assist in preventing collapse
3. It also has the effect of reducing viscosity and diluting, optimizing the rheological properties of drilling fluid
4. Possess certain temperature and salt resistance, suitable for freshwater and low salt drilling fluids
5. Excellent compatibility, can be used in combination with various water-based drilling fluid treatment agents
6. Quantity economy, convenient on-site use and maintenance
 
Product Advantages
-Effectively reduce the filtration loss of drilling fluid, make the mud cake thin and dense, reduce the invasion of filtrate into the formation, and assist in stabilizing the wellbore
-Ammonium ions embedded in the clay lattice suppress the hydration expansion of shale and reduce the risk of wellbore shrinkage and collapse
-Capable of diluting and de flocing, it can improve the rheological properties of mud and reduce pumping resistance
-Resistant to mild salt and calcium pollution, suitable for shallow, medium, deep well freshwater and low salt drilling fluids
-Good water solubility, fast dispersion speed, convenient for on-site mud mixing and maintenance
 
Usage
1. It can be used alone or in combination with other water-based drilling fluid treatment agents.
2. Before encountering the prone collapse layer of shale during drilling, supplement it in sections.
3. It is recommended to refer to the working conditions for the recommended dosage on site. It is suggested to conduct indoor trials to determine the optimal dosage before on-site deployment.
4. Normal circulation stirring, sufficient dissolution and dispersion can be used for drilling operations.
