Modeling and characteristic analysis of viscous resistance in annulus gap of coalbed gas well drainage pump
The viscous resistance caused by the relative motion of plunger and pump barrel is an important factor in the dynamic analysis of the drainage and production mechanism during coalbed methane exploitation. Existing studies mostly focus on deep well (1000–3000 m) large-displacement pump (usually 80–30...
