Abstract
The utility model relates to a petroleum machinery, in particular to a heat carrier circulating hollow sucker rod. The technical proposal is as follows: the sucker rod comprises connector end internal thread, a hollow rod connector, a hollow rod, a lining pipe, a hollow rod coupling and coupling end internal thread; the hollow rod connector, the coupling and the hollow rod are welded together by friction; the sealed lining pipe is arranged in the hollow rod; the lining pipe is fixed in the hollow rod connector and the hollow rod coupling; an inner pipe is connected with the inner wall of the hollow rod by the connector end internal thread and the coupling end internal thread; the inner pipe and the hollow rod form a closed circular channel. The sucker rod has the advantages of no interference and pollution to oil layers, good heat effect, flushing at ant time without shutting down the well, no affection to normal production, simple process, convenient use, good energy saving effect, increase of the effective stroke of a plunger, improved pumping effect and longer pump verification cycle.
Description
One, technical field:
The utility model relates to a kind of petroleum machinery, specifically is the circulating hollow rod of heat transfer medium.
Two, background technology:
At present, along with increasing of oil field Gao Ning, high sticking, high waxy oil well, when common hollow rod was used for the oil well heating, the energy consumption of generation was big, oil pumping cost height.
Three, summary of the invention:
The purpose of this utility model is exactly the defective that exists at prior art, and a kind of circulating hollow rod of heat transfer medium that continues to heat, eliminate the pit shaft wax deposition to body of rod outside is provided.
Its technical scheme is: the utility model comprises tip side internal thread, hollow stem joint, the hollow stem body of rod, bile duct, hollow stem box cupling and coupling end internal thread, hollow stem joint and box cupling and the hollow stem body of rod are by friction welding, the inner bile duct of the hollow stem body of rod for sealing, bile duct is fixed in hollow stem joint and the hollow stem box cupling, interior pipe is connected hollow stem body of rod inwall by the tip side internal thread with the coupling end internal thread, the interior pipe and the hollow stem body of rod form airtight circular passage.
Effect of the present utility model is: do not disturb, polluted reservoir, thermal effect is good.Not stopping to carry out clean-out service as required at any time under the well condition, do not influence ordinary production.Technology is simple, and is easy to use, good energy-conserving effect.Can increase plunger effective stroke, improve pump efficiency, prolong and test the pump cycle.
Four, description of drawings:
Accompanying drawing is a structural representation of the present utility model.
Five, the specific embodiment:
With reference to accompanying drawing, the utility model comprises tip side internal thread 1, hollow stem joint 2, the hollow stem body of rod 3, bile duct 4, hollow stem box cupling 5 and coupling end internal thread 6, hollow stem joint 2 and hollow stem box cupling 5 and the hollow stem body of rod 3 are by friction welding, the hollow stem body of rod 3 inner bile ducts 4 for sealing, bile duct 4 is fixed in hollow stem joint 2 and the hollow stem box cupling 5, interior pipe 7 is connected hollow stem body of rod inwall by tip side internal thread 1 with coupling end internal thread 6, interior pipe 7 forms airtight circular passage with the hollow stem body of rod 3.
