Preparation and High‐Temperature Stabilization Mechanism of Quaternary Copolymer Suspension Stabilizer for Cementing Spacer Fluid
Conventional spacer fluids fail at high temperatures in deep wells, causing sedimentation and poor cementing quality. In this study, a quaternary copolymer suspension stabilizer was synthesized via aqueous free‐radical polymerization. Orthogonal tests revealed that the influence of synthesis parameters on sedimenta...
