Abstract
The utility model relates to a strong stainless steel boxing sand filtering pipe which is used for the sand prevention of oil well production, in particular to a sending serious well, a fractured well and a polymer displacement oil well. The utility model comprises a supporting and connecting pup joint 1 that is a parent tube, a positioning cap 2, a stainless steel boxing sleeve 3, a positioning circlip 4 and a coupling 5. The sand filtering pipe has the advantages of small volume, light weight, convenient operation, high intensity, good compression resistance, big sectional area, good filtration performance, repeating use, etc; the utility model can be connected with various oil-well pumps. The favorable sand prevention result can be obtained by making use of the strong stainless steel boxing sand filtering pipe.
Description
Technical field:
The utility model relates to a kind of particularly shake out downhole hardware of serious well, fractured well, polymer flooding oil-extraction well of oil well production that is used for.
Background technology:
Sand production is general and thorny difficult problem in the oil field development manufacturing process.At present, on-the-spot is that solution sand production problem is adopting the sand control screen such as haydite formula, suitable oil pipe slot formula, stainless steel plate mesh formula and combined type, composite structure.Although play a role in the said goods sand control technology at the scene,, exist unsatisfactory part respectively owing to reasons such as structure, material, processing.For example, reach more than the 100mm along joint-cutting along oil pipe slot formula sand control screen, thereby intensity and load performance are relatively poor, are prone to and burst phenomenon, also there are shortcomings such as area of passage is little, consumption is big, cost height in this kind screen casing; The shortcoming of haydite formula screen casing is an easy fracture, and the fracture back is difficult to salvage; Though stainless steel plate mesh formula screen casing area of passage is big, oozes good fluidity, because of tube wall is too thin, its compressive resistance is poor, be prone to take out the distortion or take out leakage, cause the sand card.
Summary of the invention:
The purpose of this utility model is to provide the high-strength stainless steel boxing sand screen that a kind of intensity height and area of passage are big, ooze good fluidity.
The utility model is to realize like this.This device is made up of support and connection pipe nipple (abbreviation parent tube), stainless steel boxing sleeve, box cupling, positioning cap, location jump ring, and the support and connection pipe nipple outside is set with stainless steel boxing sleeve, and the lower end is connected with box cupling with screw thread; Stainless steel boxing sleeve upper end is provided with positioning cap and dead with the weldering of support and connection pipe nipple, and the lower end is provided with the location jump ring, and sleeve is fixed.Because this kind sand screen adopts the stainless steel wire of special cross-section through chamfered, on special equipment, use the boxing of advanced technologies art technology, and stainless boxing sleeve lining is provided with 20 root support rods, is the dome-shaped load-bearing in addition, and its tube wall withstand voltage properties and intensity are improved greatly.Because this kind sand screen stainless steel wire cross section is between 1.8-2.2mm, the slit spacing only is 1.8-2.2mm after the boxing, it is slit spacing reckling in present all screen casings, thereby has a super large area of passage, stainless steel wire is through chamfered in addition, inside and outside sealing slightly is the trumpet type depression after the boxing, and its seepage flow is also improved greatly.In addition, stainless steel boxing sleeve adopts dismountable fixed form, and the oil well operation is pulled down the location jump ring after taking out sand screen, washes away solidfied materials such as silt particle, paraffin with high-pressure water heating, dries the back and installs promptly reusable.
The utility model volume is little, in light weight, can be connected with various oil well pumps, operation is convenient, have intensity height, good pressure-resistant performance, area of passage big, ooze good fluidity, advantage such as reusable, utilize it can obtain good sand controlling result, be suitable for fractured well especially, the serious well that shakes out, polymer displacement oil well use.
Description of drawings: accompanying drawing is a structural representation of the present utility model.
The specific embodiment: enforcement of the present utility model is illustrated below in conjunction with accompanying drawing.
As shown in the figure, the utility model is made up of support and connection pipe nipple 1, positioning cap 2, stainless steel boxing sleeve 3, location jump ring 4, box cupling 5, its structure, assembled relation are as follows: support and connection pipe nipple 1 outside is set with stainless steel boxing sleeve 3, and the lower end is connected with box cupling 5 with screw thread; Stainless steel boxing sleeve 3 upper ends are provided with positioning cap 2 and dead with support and connection pipe nipple 1 weldering, and the lower end is provided with location jump ring 4 and stings tight with support and connection pipe nipple 1 with screw thread and sleeve 3 is fixing.Wherein, support and connection pipe nipple 1 adopts 2 7/8, and " the TBG oil pipe is made, and is evenly equipped with a plurality of flowing holes on its middle part tube wall, and two ends are respectively equipped with and connect that to use screw thread, joint length be 1.5m or 2m.Stainless steel boxing sleeve 3 is made up of baffle ring 6, steel wire 7 and support rod 8, be uniformly distributed along the circumference 20 surplus a support rod 8 upper/lower terminals respectively with 6 welding of upper and lower baffle ring, it is the stainless steel wire 7 of 1Cr18Ni19T that support rod 8 outsides adopt special equipment and advanced technologies art technology along the Zhou Fangxiang boxing material to be arranged, stainless steel wire 7 cross sections are special and through chamfered, wide is 1.8-2.2mm, the overcurrent slit is selected for use between 0.05-0.3mm, inside and outside sealing is the flare depression slightly, and support rod 8 materials are identical with steel wire 7.Location jump ring 4 is an annulus, and its inner headed face is provided with and the parent tube 1 periphery screw thread of interlock mutually.
