Development of a High-Temperature and High-Salinity Resistant Branched Polymer for Controlling Fluid Loss of Water-Based Drilling Fluids

Conventional fluid-loss reducers lack thermal and salt resistance and exhibit a pronounced viscosity-enhancing effect in bentonite-based drilling fluids. These issues will cause severe problems during drilling operations. Herein, a branched fluid-loss reducer, BPJ, was synthesized using BPEI1800 as the branching core a...
