MODEL: ZDQ Series
Four-Stage Pulse Swirl Oscillator
Overview
The four-stage pulse swirl oscillator uses hydraulic pulse-vibration principles. Hydraulic vibration and pulses generate waves that transfer energy to the medium and disrupt structures between particles and molecules.
This action improves the rheological behavior of drilling fluid and cement slurry, changes particle and molecular motion, reduces drilling-fluid viscosity, improves displacement efficiency and strengthens cement bonding at both interfaces of the cement sheath.
