Description
One, technical field
The utility model relates to the heating sucker rod sealing centralizer of using on a kind of electrical heating pumpingh well polished rod eye top.
Two, background technology
Some heavy oil wells of oil field all are to add cable in the bar and heat to wellbore oil hollow taking out, and reduce viscosity of crude, are convenient to extract out.The hollow rod joint that has in process of production connects bad crude oil and can enter in the hollow rod, the hollow boom end of taking out flows out from polished rod eye top, stream polished rod eye on, all be crude oil on the hollow oil pumping polish rod and on the production tree, clean because of being that viscous crude is very difficult, additionally increased oil recovery workman's workload, simultaneously also lose a lot of crude oil, cause very big economic loss to the oil field.Above-mentioned hollow rod promptly is a heating sucker rod.
Three, summary of the invention
The purpose of this utility model provides a kind of heating sucker rod sealing centralizer, solves polished rod eye top heating sucker rod and flows oily problem.
The technical solution of the utility model realizes in the following manner:
The utility model is made up of heating sucker rod, packing box, packing pressure cylinder, pipe nipple, union, pillar and packing, it is characterized in that heating sucker rod is connected with the packing box lower thread, top is connected with the pipe nipple lower thread, and the middle part is made as the packing chamber, top, packing chamber is provided with the packing pressure cylinder, and the bottom is provided with packing; Pipe nipple top is threaded with union, and the pillar that is threaded on union top, cable protecting tube are provided with the through hole of cable.
Packing box is made as the box cupling type, and the periphery middle part is provided with the spanner rib.
The utility model has solved polished rod eye top heating sucker rod and has flowed oily problem, has reduced oil recovery workman's the workload of getting clean health clear, and has avoided the crude oil loss.
Four, description of drawings
Accompanying drawing is a structural representation of the present utility model.
1-heating sucker rod, 2-packing box, 3-packing pressure cylinder, 4-pipe nipple, 5-union, 6-pillar, 7-packing among the figure.
Five, the specific embodiment
For further disclosing the technical solution of the utility model, elaborate by embodiment below in conjunction with Figure of description:
The utility model is made up of heating sucker rod 1, packing box 2, packing pressure cylinder 3, pipe nipple 4, union 5, pillar 6 and packing 7, it is characterized in that heating sucker rod is connected with the packing box lower thread, top is connected with the pipe nipple lower thread, the middle part is made as the packing chamber, top, packing chamber is provided with the packing pressure cylinder, and the bottom is provided with packing; Pipe nipple top is threaded in the pillar that union top is threaded with union, and cable protecting tube is provided with the through hole of cable.
When using the utility model, at first with packing box 2 be exposed on the heating sucker rod 1 screw thread head on polished rod eye top, cable is passed the cable through-hole of packing box 2, packing pressure cylinder 3, pipe nipple 4, union 5 and pillar 6, in packing box, add packing 7, press the packing pressure cylinder, to be screwed in the pipe nipple that union, pillar connect on the packing box, suitably compress packing, get final product with cable seal, the crude oil that leaks heating sucker rod in the well just can not flow out from the heating sucker rod upper end, prevent contaminated environment, crude oil runs off.
