Material Description
Using hyperbranched stereomolecular structure, polymer powder was synthesized by copolymerization modification of special functional monomers. Molecules possess high-density adsorption, sealing, temperature and salt resistant active groups, which can efficiently adsorb clay particles, seal formation micropores, optimize mud cake quality, and stabilize the overall system performance of water-based drilling fluids under high temperature and high salt conditions.
 
Core selling point
1. Oversized three-dimensional structure, high temperature resistance, high salt resistance, suitable for complex formations in deep wells
2. Effectively block and prevent collapse, suppress shale hydration and expansion, stabilize the wellbore and prevent collapse
3. Excellent filtration reduction effect under high temperature and high pressure, with extremely low performance degradation after aging
4. Low viscosity without thickening, optimized rheological properties of water-based drilling fluid, good construction fluidity
5. Excellent compatibility, can be freely compounded with various water-based drilling fluid treatment agents
6. Small on-site dosage, fast dissolution, high cost-effectiveness, reducing comprehensive drilling costs
 
Product Advantages
-The blocking and inhibition effect is outstanding, effectively suppressing the hydration and dispersion of shale, reducing complex situations such as block falling and collapse underground, and ensuring smooth tripping and electrical testing operations
-Excellent flow control performance, stable mud viscosity after high-temperature aging, and long-lasting and controllable performance of water-based drilling fluid system
-Strong resistance to calcium, magnesium, and saltwater pollution, suitable for stable use in deep wells, ultra deep wells, and high salt formations
-Excellent water solubility, fast dispersion speed, no need for prior alkalization or hydration, simple and convenient on-site maintenance
-It can form ultra-thin, dense and tough mud cake, with good well protection effect, effectively regulating the wellbore diameter, and reducing reservoir damage
 
Usage
1. It can be used alone or in combination with other water-based drilling fluid treatment agents.
2. Deep wells, high salinity, and prone to collapse formations can be supplemented in sections in advance, and the effect is better when added before construction weighting.
3. On site recommended dosage should refer to actual working conditions. It is recommended 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.
 
Storage precautions
