  • Does hydrophobic polyamine shale inhibition improve branched cationic polyamine inhibition performance?
  • Conclusions In this study, a hydrophobic polyamine shale inhibitor was prepared by introducing a hydrophobic group into the molecular structure of a branched cationic polyamine. After introducing the hydrophobic functional group, the shale inhibition performance was significantly improved.
  • What is hydrophobic cationic polyamine shale inhibitor (HCPA)?
  • Wellbore instability in complex shale formations is a major technical problem that threatens drilling safety and efficiency. In this paper, a hydrophobic cationic polyamine shale inhibitor (HCPA) was prepared by introducing a hydrophobic group in the molecular structure of an amine-based shale inhibitor having a branched structure.
  • What is liquid polyamine shale additive?
  • Liquid polyamine shale additive KLA-STOP™ liquid polyamine shale additive is used in polymer-based drilling and drill-in fluids. Shale inhibition is achieved by preventing water uptake by clays and by providing superior cuttings integrity.
  • Are polyamine inhibitors effective in high-performance water-based drilling fluids?
  • It is of great significance for developing high-performance water-based drilling fluids to develop a polyamine inhibitor with excellent inhibition performance and establish a systematic method to analyze the action mechanism of polyamine inhibitors. At present, the most widely studied chain-like polyamine inhibitors are widely used.
