API 11AX Downhole Oil Extraction Tool Sucker Rod Pump
The subsurface sucker rod pump is an important equipment of rod
extracting system that extracts the fluid in the oilwell powered by
pumping units and sucker rod, which is also referred to as insert
pump as its plunger is attached to, moves up and down with the
sucker rod string. It is suitable for reducing the time of workover
for deep well as it is not neccessary to pull all the tubing out of
the well hole when checking the pump, which makes the operation
quicker and the service life of tubing longer.The rod pump is in a
state of free hanging, so it is suitable for deviated wells.
According to seating mode ,the rod pump can be divided into two
types: cup hold-down and mechanical hold-down. According to
anchored position, the pump can be divided into top hold-down pumps
and bottom hold-down pumps which include stationary barrel and
traveling barrel types.
How to Use Sucker Rod Pump?
1. Before leaving the pump, you must check the factory mark and
certificate on the pump. Confirm that it is the oil pump required
for this oil well, and carefully check whether the pump barrel is
bent, whether the exposed threads are damaged or corroded, and
whether the connection parts of each thread are loose.
2. For the oil pump that has been in stock for more than one year,
the plunger and pump barrel should be cleaned before going down the
well, and the plunger should be pulled back and forth.
3. The well site where the pump is to be pumped must be kept clean
and tidy to prevent sand or other things from falling into the well
and affecting the normal pumping of the pump. A final inspection
should be performed when lowering the pump. To ensure that the
protective cap, plug and protective entanglement are all removed.
4. When the centralizer is used in the lower pump, the installation
position of the lowermost centralizer should be as close as
possible to the oil pump to ensure the alignment of the pump and
the oil pipe, thereby reducing pump wear.
5. During the downhole work of the oil pump, periodic inspections
must be carried out and the working conditions must be recorded.
6. In the case of lower rod pumps, you can first lower a supporting
stub along the tubing to the specified lower pump depth; a complete
set of rod pumps with (supporting the stub on the tubing string)
supporting assembly with the sucker rod string Into the tubing, the
depth of the pump must be sealed according to the position of the
shorting of the lower support during the downhole process, and then
the anti-impact distance of the pump is raised by 300mm, and the
oil can be transferred into the pump.
