Abstract
The utility model discloses a sand control screen pipe used for well completion of oil and water wells in an oil field. An oil pipe or a casing is drilled as a base pipe of the sand control screen pipe, a sand control sleeve cut with a narrow slit is sleeved on a drilling segment of the base pipe, two ends of the sand control sleeve are welded with baffle rings and are welded with the base pipe through the baffle rings, a groove is pressed on the sand control sleeve at intervals, so that only the groove is in contact with the base pipe during the assembling with the base pipe, the liquid conveniently flows into the base pipe through the narrow slit of the sand control cover, a fastening ring is arranged outside the sand control groove, so that the sand control sleeve is fixed on the base pipe, and the sand control sleeve is prevented from being damaged during the downhole of the sand control screen pipe and the lateral deviation of the sand control sleeve at the high-angle deviated downhole is prevented; a supporting ring is fixed and welded along the circumference at intervals in the axial direction of the base pipe, and a collar is threadedly connected with the baffle rings. The sand control screen pipe solves the problems of short sand control time, easy damage, poor sand control effect and high manufacturing cost of the existing sand control screen pipe in the prior art and can be widely used for the well completion of the oil and water wells in the oil field.
Description
Technical field:
A kind of sand control screen that the utility model provides a kind of oil field oil, well completion to use.
Background technology:
At present, oil well has a variety of structures with sand control screen---metallic fiber sand control screen, cutting seam sieve tube, wire-wrapped screen, restraining liner etc.These screen casings or cost are higher, and perhaps the sand control time is short, perhaps fragile or sand controlling result is undesirable.The quality of sand control screen and life-span all have a direct impact oil gas well production and life-span, in case sand control lost efficacy, light then influence the ordinary production of oil gas well, heavy then cause oil well to be scrapped.
The utility model content:
The purpose of this utility model provides a kind of sand control screen, and this sand control screen has solved the problem that the existing sand control screen sand control time is short, fragile, sand controlling result is poor, cost is high that exists in the prior art.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of sand control screen, form by parent tube, baffle ring, sand control cover, groove, firm ring, support ring, box cupling; Boring is as the parent tube of sand control screen on oil pipe or sleeve pipe, one section that holes on the parent tube puts the sand control cover that cuts narrow slit, sand control cover two ends are welded with baffle ring, and by baffle ring and parent tube welding, put every a segment distance at sand control and to be pressed with a groove, it only flutedly when assembling with parent tube is contacted with parent tube, being convenient to liquid enters in the parent tube by sand control cover narrow slit, the sand control groove is adorned a dead ring outward, the sand control cover is fixed on the parent tube, and the sand control cover damages and the big gradient place sand control cover lateral deviation in the down-hole when preventing that sand control screen from going into the well; Axially fix a support ring along circumference at parent tube every a segment distance, and with its welding; Box cupling is threaded with baffle ring.Should anti-sandpipe be to realize like this in the sand control implementation process; The box cupling of this sand control screen upwards is connected with the top completion tubular column, parent tube be lowered into well after the bottom completion tubular column is connected in the precalculated position give up to hang and get final product.
The beneficial effects of the utility model are, this sand control screen is simple in structure, and the sand control cost is low; This sand control screen is the combined type screen casing of one for punching screen casing and cutting seam sieve tube, and the intensity of its existing punching screen casing has sand control, the filter sand effect of cutting seam sieve tube again.
Description of drawings:
Fig. 1 is the utility model overall structure schematic diagram.
Fig. 2 is the utility model support ring position view.
Among the figure 1, parent tube, 2, baffle ring, 3, the sand control cover, 4, groove, 5, firm ring, 6, support ring, 7, box cupling.
The specific embodiment:
In the drawings, a kind of sand control screen is made up of parent tube 1, baffle ring 2, sand control cover 3, groove 4, firm ring 5, support ring, 6 box cuplings 7; Boring is as the parent tube 1 of sand control screen on oil pipe or sleeve pipe, one section of boring puts the sand control that cuts narrow slit and overlaps 3 sand controls and overlap 3 two ends and be welded with baffle ring 2 on the parent tube 1, and by baffle ring 2 and parent tube 1 welding, on sand control cover 3, be pressed with a groove 4 every a segment distance, it only fluted 4 is contacted with parent tube 1 with parent tube 1 assembling the time, being convenient to liquid overlaps 3 narrow slits by sand control and enters in the parent tube 1, the sand control groove 4 outer dead rings 5 of adorning, sand control cover 3 is fixed on the parent tube 1, and sand control cover 3 damages and big gradient place sand control overlaps 3 lateral deviations in the down-hole when preventing that sand control screen from going into the well; Axially fix a support ring 6 along circumference at parent tube 1 every a segment distance, and with its welding; Box cupling 7 is threaded with baffle ring 2.
