Material Description
The multi-component polymer resin powder obtained by graft copolymerization of lignite humic acid macromolecules and sulfomethyl phenolic resin is rich in sulfonic acid groups and hydroxyl active groups, which can strongly adsorb clay particles, optimize the mud cake structure, and stabilize the comprehensive performance of water-based drilling fluid under high temperature and high salt conditions.
Core selling point
1. Excellent high temperature resistance, suitable for deep and ultra deep well operation conditions
2. Salt resistant and resistant to calcium and magnesium pollution, both freshwater and saltwater drilling fluids can be used
3. Efficiently reduce high temperature and high pressure filtration loss, forming thin, tough and dense mud cake
4. It has both anti collapse and suppression effects, assisting in stabilizing the wellbore wall
5. Excellent compatibility, can be used in combination with various water-based drilling fluid treatment agents
6. Moderate viscosity effect, controllable on-site dosage, maintaining the stability of the mud system
Product Advantages
-Stable filtration performance after high temperature aging, effectively controlling high temperature and high pressure filtration, and reducing filtrate invasion into the formation
-The mud cake is thin, dense, and tough, reducing the friction resistance of the mud cake, inhibiting the hydration of shale, and reducing the risk of well collapse
-Salt resistant, resistant to calcium and magnesium ion pollution, with minimal performance degradation in high salinity drilling fluids, and strong adaptability to complex formations
-Mild impact on the rheological properties of drilling fluid, less likely to cause abnormal increase in viscosity and shear, suitable for medium and high-density mud
-Good water solubility, fast dispersion speed, simple and convenient on-site adjustment and maintenance
Usage
1. It can be used alone or in combination with other water-based drilling fluid treatment agents.
2. Before encountering deep wells or high salt formations that are prone to collapse, segmented replenishment can be carried out in advance; It is recommended to add high-density drilling fluid before weighting.
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.
Storage precautions
Sealed and moisture-proof, avoiding exposure to sunlight and rain; Use up as soon as possible after opening; Wear dust-proof protective equipment during operation.
