Abstract
The utility model discloses an anti-falling oil extraction and paraffin prevention device which consists of a component A and a component B, wherein the component A consists of a paraffin prevention alloy pipe and an outer sleeve pipe A which are fixedly connected with each other through a convex combiner A; the component B consists of an inner pipe and an outer sleeve pipe B which are fixedly connected with each other through a convex combiner B; the tail end of the component B is sleeved in the convex combiner A of the component A; three or four welding points are arranged at joints of the outer sleeve pipe B and the convex combiner A as well as the paraffin prevention alloy pipe; preferably, the outer sleeve pipe B is in threaded connection with the convex combiner A and the paraffin prevention alloy pipe. The structural shape of the anti-falling oil extraction and paraffin prevention device can meet a requirement that any alloy surface is in full contact with raw oil and does not produce obvious resistance to flowing of the raw oil; three or four uniformly distributed welding points are additionally added at joints of the outer sleeve pipe B and the convex combiner A as well as the paraffin prevention alloy pipe, so that long-time continuous impact of the raw oil is effectively prevented; the outer sleeve pipe B is in threaded connection with the convex combiner A and the paraffin prevention alloy pipe, so that the anti-falling oil extraction and paraffin prevention device is difficult to loose.
Description
Technical field
The utility model relates to oil exploitation down-hole mechanical field, particularly relates to the oil recovery wax-proofing apparatus of the slip-off preventing that prevents in a kind of oil exploitation process that oil pick-up tube from stopping up.
Background technology
Generally all contain wax in the crude oil, China has many oil fields paraffin content very high.When oil producing operation, crude oil constantly reduces owing to temperature from the process of subsurface to surface, wax in the crude oil can be separated out after temperature reaches wax precipitation point (generally about 40 ℃) and be condensed at sucker rod and tube wall, the operation that finally causes pumping stops, must remove the wax that solidifies by " well-flushing " and could continue oil pumping, clear wax control becomes the important technical links of crude oil production.And oil pick-up tube leaks easily, just can restart the operation of pumping after need stopping oil producing operation and experiencing the maintenance of a couple of days, has a strong impact on the production efficiency of crude oil.
The utility model content
The purpose of this utility model is to provide a kind of separating out and the oil recovery wax-proofing apparatus of the novel slip-off preventing of the function of reuniting of wax in the crude oil for inhibiting that have, this oil recovery wax-proofing apparatus can effectively prevent oil pick-up tube leakage, come off.
The utility model is to realize like this, a kind of oil recovery wax-proofing apparatus of slip-off preventing, formed by A assembly and B assembly, described A assembly is connected and fixed by convex combiner A by wax control compo pipe, outer tube A, it is characterized in that: described B assembly is connected and fixed by convex combiner B by interior pipe and outer tube B; The end of described B assembly is sleeved among the convex combiner A of described A assembly, and the connecting portion of outer tube B and convex combiner A, wax control compo pipe is provided with three or four solder joints;
Preferably, outer tube B and convex combiner A, wax control compo pipe are by being threaded;
Wax control compo pipe described in the utility model is provided with two sections, has a large amount of equally distributed apertures on every section the wax control compo pipe tube wall; Have the great amount of evenly-distributed aperture on the described inner pipe wall;
The oil recovery wax-proofing apparatus of the slip-off preventing that the utility model provides, its advantage is as follows:
1. planform of the present utility model can satisfy fully contacting of any alloy surface and crude oil, and flowing of crude oil do not produced obvious resistance, is applicable to pumpingh well, flowing well and ground crude oil transportation system.
2. the utility model is the reunion behavior that changes wax electronic structure of molecule and then change wax crystalline substance by electrochemical action, effectively suppress and slow down the piece that condenses into of wax, impel the wax of separating out to float on a liquid with small crystal habit and with liquid flow, therefore effectively prevent and delay wax condensing on tube wall, sucker rod, thereby prolong the clean-out service cycle of oil well.
3. the connecting portion of outer tube B and convex combiner A, wax control compo pipe has increased by three or four equally distributed solder joints, prevented that effectively the connecting thread of outer tube B and convex combiner A, wax control compo pipe is difficult for loosening because crude oil constantly impacts for a long time.
Description of drawings

Fig. 2 is the structural representation of the utility model B assembly.
Among the figure 11, the wax control compo pipe, 12, outer tube A, 13, convex combiner A, 21, interior pipe, 22, outer tube B, 23, convex combiner B.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing
A kind of oil recovery wax-proofing apparatus of slip-off preventing, formed by A assembly and B assembly, described A assembly is connected and fixed by convex combiner A13 by wax control compo pipe 11, outer tube A12, it is characterized in that: described B assembly is connected and fixed by convex combiner B23 by interior pipe 21 and outer tube B22; The end of described B assembly is sleeved among the convex combiner A13 of described A assembly, and the connecting portion of outer tube B22 and convex combiner A13, wax control compo pipe 11 is provided with three or four solder joints;
Preferably, outer tube B22 and convex combiner A13, wax control compo pipe 11 are by being threaded;
Wax control compo pipe 11 described in the utility model is provided with two sections, has a large amount of equally distributed apertures on every section wax control compo pipe 11 tube walls; Have the great amount of evenly-distributed aperture on pipe 21 tube walls in described;
During concrete the use, A assembly and B component string are connected in the oil well pipeline, crude oil enters wax control compo pipe 11 hypomeres from the lower end of A assembly, under immense pressure, from wax control compo pipe 11 tube wall apertures, be ejected into the groove between outer tube A12 and the wax control compo pipe 11, and it is upwards mobile along groove, be ejected in wax control compo pipe 11 epimeres from epimere channel bottom aperture, thereby flow in the B assembly, area of space under oil pressure, being ejected into from interior pipe 21 tube wall apertures between pipe 21 and the outer tube B22, upwards flow again, enter the oil pumping pipeline by convex combiner B23 at last.
