1.TUBING PUMP
Composed by the pump assembly, standing valve assembly and the plunger assembly, tubing pump is named for the tube device (including the tube pump, the extension joints, etc.) directly connected to the tubing by thread. It has the following characteristics:
1. Larger OD than the rod pump under the same tubing bore, preferable for large displacement wells
2. Solid structure and big flow area, better for viscous crude oil production.
3. Suitable for shallow and deep wells with larger displacement.

2. ROD PUMP
Because plunger is linked with rod moving together up and down, and pump barrel is fixed at the top or the bottom by fixtures, the pump characterizes as follows:
1. Free from the tensile load caused by weight of the oil column, the pump barrel only bears external pressure which favors deep wells, for small gap changes between pump and plunger.
2. Comparing with other standardized pumps for deep wells, it has higher resistance for compression break or bending deformation.
3. Due to the effects that pump body swinging around the fixtures at the bottom, it can be used in deviated wells.
4. It is not suitable for long stroke pump, nor sand wells, because easy sand accumulation in the annular space between the pump and tubing would result in pump wedging.

3. Tubing pump for sand control
By reducing the inflow of sand, sand burying and wedging are prevented, lower wearing and longer service life could be attained.
Applicated to Sand volume less than 0.08% of the total mount
