Assignment task:
A conventional sucker rod pumping unit, C-320-213-86, is used to lift fluid from an oil well. With information given below:
- Oil gravity is 30 oAPI.
- Oil viscosity is 1.0 cp.
- Oil formation volume factor is 1.2 rb/stb
- The tubing is not anchored.
Answer the following questions:
1. The position of the walking beam-pitman connection point assuming its trajectory flows arc MN in Figure 1) as a function of crank arm position or rotation time for a whole cycle (0 to 360o)
2. The position of plunger as a function of crank arm position or rotation time for a whole cycle (0 to 360o)
3. The acceleration of the plunger during an upstroke and downstroke cycle
4. The polished rod load during an upstroke and downstroke cycle
