Product introduction<\/strong><\/p>\n\n\n\n<p>This product is not only suitable for low solid non dispersible polymer drilling fluid system, but also for dispersed drilling fluid system. There are carboxyl, sodium carboxy, calcium carboxy, amide and other functional groups in the molecular chain. After optimization, various groups in the molecule have strong salt resistance, calcium and magnesium resistance and temperature resistance. They are mainly used for low solid non dispersible polymer water-based drilling fluid. They can improve rheological parameters, improve shear dilution ability, reduce filtration loss, coat drilling cuttings and drilling cuttings and cut out dispersion.<\/p>\n\n\n\n<p><strong>2.

Purpose and function<\/strong><\/p>\n\n\n\n<p>The copolymer of acrylamide and sodium acrylate has the functions of increasing viscosity, flocculation, changing flow pattern and reducing filtration in drilling fluid. When it is added to the drilling fluid, the drilling fluid can maintain a small n value, effectively adjust the flow pattern, inhibit shale dispersion, resist inorganic ion pollution and reduce the filtration of drilling fluid, so as to improve the drilling speed, reduce downhole complex accidents and reduce the drilling cost.<\/p>\n\n\n\n<p><strong>4. Use guide<\/strong><\/p>\n\n\n\n<p>Dosage: 0.5-1.0%. Pay attention to the feeding speed and preferably high-speed mixing and shearing.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>1.
