Abstract
The utility model relates to a sand-proof apparatus used in an oil production well. The sand-proof apparatus comprises an upper joint, a sand-proof outer tube, a sand-proof inner tube assembly and a lower joint, wherein the two ends of the sand-proof outer tube are respectively connected with the upper joint and the lower joint; the sand-proof inner tube assembly is connected with an upper tip and is arranged in the sand-proof outer tube; the sand-proof inner tube assembly consists of a skeleton and a sand filter screen; the skeleton is a round-bag type skeleton consisting of an upper connector, a support ring, a support retaining ring, a beam and a lower support plug; and the sand filter screen is sleeved on the skeleton. The utility model has the advantages that the service life is long, the structure is simple, and the sand content and impurities in the crude oil can be effectively filtered.
Description
Technical field:
The utility model relates to a kind of a kind of sand control installation that uses in producing well.
Background technology:
In the oil pumping exploitation of oil field, accident that sand production often causes that oil well sand card, sand plug, sucker rod are broken etc., thus cause that oil well repair free period is short, consequences such as operating cost and Master Cost increase.
The sand control installation kind of China's application at present is more, with regard to sand controlling result pluses and minuses is arranged respectively.To solve oil well sand preferably and suffer from, very big space is in addition innovated in the development of sand control installation.
Summary of the invention:
Purpose of design of the present utility model aims to provide a kind of long service life, and is simple in structure, can effectively filter a kind of sand control installation that contains sand and impurity in the crude oil.
The technical solution of the utility model is:
Sand control installation, include top connection, sand control outer tube, sand control inner tube assembly and lower contact, the two ends of sand control outer tube connect top connection and lower contact respectively, the sand control inner tube assembly connects upper end and is positioned at sand control outer tube inside, the sand control inner tube assembly is made up of skeleton and filter gauze, wherein skeleton is made circle bag type skeleton by upper binding head, support ring, support retaining ring, beam, lower support plug, and the filter sand net is contained on the skeleton.
Preferably, beam adopts the stainless steel rib.
Preferably, the filter sand net adopts stainless steel filter sand net.
Preferably, pin is set upright in setting on the sand control inner tube assembly.
Preferably, the sand control inner tube assembly is suspended in the sand control outer tube by the screw thread of last jointing and top connection.
The beneficial effects of the utility model are: beam becomes circle bag type skeleton with upper binding head, support ring, support retaining ring, lower support plug assembly welding.It is promptly carried out effectively the filter sand net and supports, and can not form and stops and cover entering liquid again, can guarantee effective feed liquor duct of filter sand net, does not stay the deposition dead angle to fine silt again.Filter sand net and skeleton are all selected stainless steel material for use, are in order to improve the corrosion resistance in corrosive medium, can to guarantee the intensity and the application life of skeleton and filter sand net.The sand control inner tube assembly is suspended in the sand control outer tube, is in order to guarantee that the annular gap between the pipe is enough and even in sand control outer tube and the sand control, sand setting to be sunk smoothly to the tail pipe pocket under unobstructed state.

The specific embodiment
Sand control installation, include top connection 1, sand control outer tube 2, sand control inner tube assembly 3 and lower contact 4, the two ends of sand control outer tube 2 connect top connection 1 and lower contact 4 respectively, sand control inner tube assembly 3 connects upper end and is positioned at sand control outer tube 2 inside, sand control inner tube assembly 3 is made up of skeleton and filter sand net 10, wherein skeleton is made circle bag type skeleton by upper binding head 5, support ring 6, support retaining ring 8, beam 7, lower support plug 9, and filter sand net 10 is sleeved on the skeleton.
Be provided with on the sand control inner tube assembly 2 and set upright pin 11, sand control inner tube assembly 3 is suspended in the sand control outer tube 2 by the screw thread of last jointing and top connection 1.
In the sand well manufacturing process, the load fluid body enters inner chamber by many rounds eye of sand control outer tube 2, and big particulate matter is simultaneously by filtering, and the load fluid body that enters inner chamber stops sand grains offline by tubular stainless steel filter sand net 10.Sink down in the tail pipe pocket by the gap between outer tube 2 and the sand control inner tube assembly 3, the liquid that is filtered sand enters oil pipe, discharges pit shaft through oil well pump.
Should be noted that at last: above embodiment only is not intended to limit in order to the explanation the technical solution of the utility model; Although with reference to preferred embodiment the utility model is had been described in detail, those of ordinary skill in the field are to be understood that: still can make amendment or the part technical characterictic is equal to replacement the specific embodiment of the present utility model; And not breaking away from the spirit of technical solutions of the utility model, it all should be encompassed in the middle of the technical scheme scope that the utility model asks for protection.
