Abstract

The utility model relates to a liquid filter for the sand control before the pump, in particular to oil recovery sand control ware. The cover is equipped with a sand control section of thick bamboo on the device's the parent tube, and sand control section of thick bamboo both ends are fixed on the parent tube through the lantern ring respectively, and a sand control section of thick bamboo comprises an outer sand control section of thick bamboo and an inlayer sand control section of thick bamboo, and outer sand control barrel casing dress adopts stainless steel orifice plate to make at the inlayer sand control section of thick bamboo outside, an outer sand control section of thick bamboo, and an inlayer sand control section of thick bamboo adopts the metal cystosepiment to make, and it has a plurality of annular diversion grooves to process on the corresponding parent tube outer wall of an inlayer sand control section of thick bamboo, and annular diversion grooves is a plurality of water conservancy diversion holes of equipartition upward. The utility model discloses a double -deck sand control, the sand control is effectual, avoids causing the holddown phenomenon, the life of extension oil -well pump, parent tube surface liquid flow resistance is little, and the oil -well pump is efficient, and a sand control section of thick bamboo can wholly be dismantled and restore, and sand control ware after the restoration can used repeatedly, and use cost is low.

Description

Oil extraction sand prevention device

Technical field：

This utility model is related to sand control liquid filter before a kind of pump, more particularly to a kind of oil extraction sand prevention device.

Background technology：

People extract underground petroleum using oil well pump, with suction pump groundwater abstraction and river, in order to prevent silt particle from entering Enter pump chamber, the use for extending pump is received the order, so the liquid filter of an interception suspended particle in liquid is just mounted with before pump, This filter is just referred to as sand control device.However, existing sand control device is all single-stage (monolayer) sand control cylinder, sand controlling result is poor, easily Cause silt particle to enter pump chamber, cause holddown phenomenon.Sand control device base tube surface liquid flow resistance is big, and the oil pumping efficiency of pump is low.It is existing Sand control device be unrepairable, cause production cost high and the wasting of resources.

Utility model content：

The technical problems to be solved in the utility model is to provide a kind of oil extraction sand prevention device, the arrangement achieves double-layer anti-sand, Sand controlling result is good, it is to avoid cause holddown phenomenon, extends the service life of oil well pump, and base tube surface liquid flow resistance is little, oil pumping The efficiency of pump is high, and sand control cylinder be able to can be reused with integral demounting and reparation, the sand control device after reparation, and use cost is low.Overcome Existing sand control device sand controlling result is poor, and base tube surface liquid flow resistance is big, and the oil pumping efficiency of pump is low, and sand control device unrepairable makes The deficiency of the high and wasting of resources into production cost.

Technical solution adopted in the utility model is：A kind of oil extraction sand prevention device, including tubing coupling and base tube, base tube one End connected pipes box cupling；Sand control cylinder is set with base tube, sand control cylinder two ends are fixed on base tube by the collar respectively, sand control cylinder by Outer layer sand control cylinder and internal layer sand control cylinder composition, outer layer sand control jacket casing are mounted on the outside of internal layer sand control cylinder, and outer layer sand control cylinder is using stainless Steel orifice plate is made, and internal layer sand control cylinder is made using metal foam sheets, is machined with many on the corresponding base tube outer wall of internal layer sand control cylinder Individual annular diversion groove, uniform multiple pod apertures on annular diversion groove are convex annular between two neighboring annular diversion groove Edge, is provided with a plurality of guiding gutter that can connect two neighboring annular diversion groove in annular flange flange.

Annular diversion groove width 60mm, deep 1.5mm.

The beneficial effects of the utility model are：This utility model realizes double-layer anti-sand, and sand controlling result is good, it is to avoid cause card Pump phenomenon, extends the service life of oil well pump, and base tube surface liquid flow resistance is little, and oil well pump efficiency high, sand control cylinder can be with whole Body is dismantled and is repaired, and the sand control device after reparation can be reused, and use cost is low.

Description of the drawings：

The utility model is described in more detail with reference to the accompanying drawings and detailed description.

Fig. 1 is structural representation of the present utility model.

Structural representations of the Fig. 2 for sand control cylinder.

Structural representations of the Fig. 3 for base tube.

Specific embodiment：

As shown in Figure 1, Figure 2, Figure 3 shows, a kind of oil extraction sand prevention device, including tubing coupling 1 and base tube 2,2 one end of base tube connection oil Pipe box cupling 1；Sand control cylinder 3 is set with base tube 2,3 two ends of sand control cylinder are fixed on base tube 2 by the collar 6 respectively, and sand control cylinder 3 is Can be with integral demounting and reparation, the sand control device after reparation can be reused, and sand control cylinder 3 is prevented by outer layer sand control cylinder 4 and internal layer Sand cylinder 5 is constituted, and outer layer sand control cylinder 4 is sleeved on the outside of internal layer sand control cylinder 5, and outer layer sand control cylinder 4 can be dismounting, after dismounting, Jing Over cleaning can be reused, and in ground handling sand control device or go into the well in operation process, and outer layer sand control cylinder 4 effectively can be protected Internal layer sand control cylinder 5, prevents 5 earlier period damage of internal layer sand control cylinder.Outer layer sand control cylinder 4 is made using stainless steel plate, internal layer sand control cylinder 5 Made using metal foam sheets, on corresponding 2 outer wall of base tube of internal layer sand control cylinder 5, be machined with 14 annular diversion grooves 8, annular Diversion groove 8 width 60mm, deep 1.5mm.Uniform multiple pod apertures 9, two neighboring annular diversion groove 8 on annular diversion groove 8 Between be annular flange flange 7, a plurality of guiding gutter 10 that can connect two neighboring annular diversion groove 8 is provided with annular flange flange 7.It is logical Cross guiding gutter 10 all of annular diversion groove 8 is connected with pod apertures 9, form unimpeded and complete liquid flow path, subtract Little liquid flowing resistance, it is ensured that the liquid after filtration smoothly enters 2 inner chamber of base tube, meets the requirement of the oil well pump course of work, carries The high oil pumping efficiency of pump, reaches the purpose of increasing both production and income.Sand control device repair procedures are simple, during repairing, except changing internal layer Outside sand control cylinder 5, remaining parts can be reused, and save workover treatment production cost.

It is understood that above with respect to specific descriptions of the present utility model, be merely to illustrate this utility model and not The technical scheme being limited to described by this utility model embodiment, it will be understood by those within the art that, still can be with This utility model is modified or equivalent, to reach identical technique effect；As long as satisfaction uses needs, all in this reality Within new protection domain.
