Polyacrylamide is usually used as an encapsulating agent in drilling fluids. Its main function is to coat and protect solid particles in drilling fluids, prevent them from adverse reactions with the well wall or formation, and at the same time improve the performance of the drilling fluids. stability and performance.
The role of polyacrylamide as a coating agent for drilling fluids:
Coating solid particles: Polyacrylamide can form a coating in the drilling fluid to wrap the solid particles and prevent them from chemically reacting, dissolving or depositing with the well wall or formation. This helps reduce wellbore stability issues during drilling and prevents formation collapse or crack formation.
Polyacrylamide-drilling fluid coating agent
Improve the stability of drilling fluid: The coating of polyacrylamide can evenly disperse the solid particles in the drilling fluid and prevent the particles from coalescing and settling, thereby improving the stability and suspension of the drilling fluid. This helps maintain drilling fluid performance and reduces the risk of operational difficulty and equipment failure caused by solid particle build-up.
Improve fluid loss control: During the drilling process, polyacrylamide can form a thin film on the well wall, filling and blocking the pores in the well wall, and reducing the filtration rate of the drilling fluid. This helps control fluid exchange between the wellbore wall and the formation, preventing the liquid phase of the drilling fluid from seeping into the formation while preventing water or other components in the formation from seeping into the wellbore.
