The tubing pump is an underground pumping device directly fixed to the bottom of the oil pipe. The plunger is driven by the pumping rod to reciprocate and lift the crude oil from the bottom of the well to the ground. Its simple structure and low cost are suitable for oil wells with medium and low production and stable well conditions, but the entire oil pipe needs to be removed during maintenance.

Characteristics of tubing pump：
The core characteristics of petroleum tubing pump are simple structure, economical and practical, mature and reliable.
The most distinctive feature of tubing pump is that the pump barrel is directly fixed at the end of the tubing column, the two form a whole and go down into the well, and the plunger is connected to the ground pumping unit through the sucker rod to drive. This integrated design gives the tubing pump the advantages of relatively simple structure and low manufacturing cost, especially suitable for projects with limited budgets or stable well conditions. Ease of installation is another major feature of tubing pump. You only need to connect the pump barrel to the bottom of the tubing and go down the well according to the design requirements.In terms of reliability, thanks to our Dongsheng Petroleum's mature design and fewer moving parts, tubing pump can provide stable pumping efficiency in conventional low- and medium-yield wells.
The difference between tubing pump and insertion pump：
| Comparison items | Tubing pump | Insert the pump |
| Installation location | Fixed at the end of the tubing | Independent of the tubing, fixed by a locking device |
| Maintenance method | The entire tubing needs to be removed | Only the pump body is discharged, and the tubing is retained |
| Applicable well conditions | Low sand content, stable well condition | High sand content, complex well conditions |
Overhaul and maintenance methods of tubing pump：
When the tubing pump itself or fixed valves and other components fail, the entire tubing column must be removed before it can be repaired or replaced. Although this brings the disadvantages of large amount of work and long shutdown time (especially compared to inserting a pump), it also avoids the complicated situation of the pump falling off underground. Therefore, tubing pump is particularly suitable for medium-deep wells (generally <3000 meters) where the well condition is relatively simple, the sand content is low, the waxing is not serious, and the frequency of workover operations is not high. The low investment threshold of tubing pump makes it still a cost-effective main lifting equipment choice in many mature oil fields or projects that are sensitive to initial costs.
FAQ:
Q1: What is a tubing pump? What is its core role in the oil recovery system?
A: Tubing pump is a kind of downhole pumping equipment fixed at the end of the oil pipe. The plunger is driven by the pumping rod to reciprocate and lift crude oil from the bottom of the well to the ground. Its core role is to provide efficient and low-cost mechanical lifting solutions for medium and shallow conventional oil wells.
Q2: Why does the entire tubing have to be removed during the overhaul of the tubing pump?
A: Since the pump cylinder of the tubing pump is directly connected to the oil pipe, when the internal components of the pump (such as fixed valves and plungers) are damaged, the entire oil pipe column must be removed before it can be repaired. This is the key maintenance feature that distinguishes the tubing pump from the insertion pump.
Q3: What well conditions is tubing pump suitable for? How should the use be optimized?
A: Tubing pump is most suitable for oil wells with a depth of <2500 meters, low sand content and stable well conditions.
Enhanced recommendations include：
(1) Regularly check the power diagram and dynamically adjust the stroke/stroke
(2) Wax-containing wells are hot-washed every 15 days, and the pump barrel is washed every 15 days.
(3) Installation of telescopic oil drain for high gas-oil ratio wells
