Abstract: A viscoelastic foam system for an acidic gas switch improves the recovery factor. The viscoelastic foam system for an acidic gas switch has a pH-switch surfactant, a hydrocarbyl anionic surfactant and water. The pH-switch surfactant is at least one of long-chain hydrocarbyl amines. After the viscoelastic foam system meets the acidic gas, the interaction between the pH-switch surfactant and the hydrocarbyl anionic surfactant is enhanced, the viscosity increases, and the formed foam has better stability and plugging performance. When the viscoelastic foam system is injected at 1.0 PV, the apparent viscosity of the foam formed in the rock core is ?270 mPa·s, which can increase the recovery factor by more than 20%, and the long-chain hydrocarbyl amine improves the salt tolerance of the single anionic surfactant, so that the applicable mineralization range of the system is increased to 10-200 g/L.

Abstract: A six-DOF motion testing and motion parameter decoupling method for rotors based on shaft-disk is proposed, which includes a displacement sensor tooling and a precision shaft-disk fixed on the rotor where three measuring points are arranged on the surface of disk to measure the axial motion of the rotor, two measuring points on the shaft to measure the radial motion, and the angle encoder at the shaft shoulder to measure the rotation motion.

The fixed coordinate system and the shaft-disk moving coordinate system are set, and the measured values of the displacement sensors and the encoder are represented by vectors to establish the relationship between the six-DOF motion of the shaft-disk axis and the measured values of sensors. Thus, the six-DOF motion of the rotor/shaft-disk can be determined by the measured data.
