Abstract
A high-density seam-punching sand control screen, which comprises a base tube with a number of oil holes on the circumference of the wall, which is characterized in that a seam-punching filter tube is connected to the external part of the oil holes, and a high-density lateral slit is precised stamped on the circumference of the wall of the seam-punching filter tube with a support ring on both ends. The high-density lateral slit of the seam-punching filter tube is distributed along the lateral axis or the spiral line. The seam-punching filter tube is welded from stainless steel plate by precision stamping. The utility model has the advantages of: precise and controllable lateral slit. The flow area is greatly widened after punching structure improvement. With a higher overall strength and deformation resistance capacity, excellent corrosion resistance, simple process, low manufacturing cost, high sand control reliability, the utility model can complement with a great variety of sand control operations, reduce the number of gas wells overhaul and improve life of gas wells. The utility model is the alternative product of the existing widely used slotted screen pipe and wire screen pipe.
Description
Technical field
The utility model relates to the oil equipment technical field, belongs to a kind of sand control screen with highly dense calking filtration, is applicable to the sand control treatment in the oil gas well development process.
Background technology
Oil gas field in the process of exploitation because geology, exploitation factor, the ubiquity phenomenon of shaking out.In loose sand oil-gas reservoir exploitation, thickened oil recovery, the oil field enters and shakes out behind the high water-cut stage more seriously, and sand control becomes the matter of utmost importance that must consider in the exploitation of oil-gas field.Sand production of oil-gas wells is the heavy corrosion underground equipment, and causes manifold of ground and the long-pending sand of oil storage tank, shakes out can form the hole outside sleeve pipe when serious, causes formation collapse, and oil well is scrapped, and brings tremendous loss to the oil field.
Facts have proved that adopting the mechanical sand control tubing string is the effective means that solves sand production of oil-gas wells.Adopt the direct sand control of sand control pipe can reduce the sand control treatment cost, improve the sand control success rate, and field operation is simple, sand control is long effective time, particularly has absolute predominance aspect the horizontal well sand control.The main both at home and abroad at present mechanical sand control pipe that adopts has: cutting seam sieve tube, wire-wrapped screen, metal wool sand screen, wire lath cloth screen casing and restraining liner etc.
The seepage area of cutting seam sieve tube is little, and aperture area is generally at 2%-6%, stitches wide greatlyyer, should not use separately.When thermal recovery steam injection, stratum corrosivity are big, can cause stitching wide variation, finally cause sand control to lose efficacy.
The seepage area of wire-wrapped screen is less, easily causes the wrapping wire pipe to run screen casing such as deformation of filament when horizontal well dog-leg section and the borehole wall are irregular and damages; Wire-wrapped screen should not use separately, most cooperation gravel pack, increase task difficulties of needing; Screen casing should not trip out after sand control loses efficacy, and increased the workover treatment amount.
Senior screen casings such as metal wool sand screen, wire lath cloth screen casing and restraining liner are owing to the processing technology complexity, and cost is higher, and applicability is limited, are difficult to obtain large-scale promotion in the oil field and use.
Summary of the invention
The purpose of this utility model provides a kind of highly dense calking sand control screen, it can overcome above defective, substitute a large amount of at present cutting seam sieve tube and wire-wrapped screens that use, has accurate controlled side direction seam, by improving the punching structure area of passage is improved greatly, have higher bulk strength and non-deformability simultaneously, good corrosion resistance, technology is simple, manufacturing cost is lower, sand control reliability height can cooperate kinds of processes to carry out sand control treatment, seepage flow rate height, etch resistant properties is good, the effect of sand control is also good, so screen sand control is reliable, has improved the application life of oil gas well.
For achieving the above object, the utility model is taked following design scheme:
A kind of high density calking sand control screen, it includes parent tube, on the tube wall circumference of this parent tube, be drilled with a plurality of oil-through holes, it is characterized in that: oil-through hole 4 is externally connected to the calking cartridge filter on parent tube, precision stamping has highdensity side direction seam on the barrel circumference of calking cartridge filter, is connected with support ring respectively at the two ends of calking cartridge filter.
Be drilled with the oil-through hole that spiral distributes on the described parent tube tube wall circumference, can effectively reduce body cross section perforated area, improved the bulk strength and the non-deformability of screen casing.Support ring is welded at described calking cartridge filter two ends respectively, and this support ring and parent tube are welded as a whole.
Highdensity side direction seam on the calking cartridge filter is to distribute or distribute along helix along axis.
The calking cartridge filter is welded after by precision stamping by corrosion resistant plate;
Corrosion resistant plate forms highdensity side direction seam through behind the precision stamping, realizes the oil catch Grains by the side direction seam then.
The utility model has the advantages that: accurate controlled side direction seam, by improving the punching structure area of passage is improved greatly, have higher bulk strength and non-deformability simultaneously, good corrosion resistance, technology is simple, manufacturing cost is lower, sand control reliability height can cooperate kinds of processes to carry out sand control treatment, can reduce oil gas well upkeep operation number of times, improving the oil gas well life-span, is a large amount of at present cutting seam sieve tubes that use and the substitute products of wire-wrapped screen.

The specific embodiment
Referring to Fig. 1, Fig. 2, Fig. 3, shown in Figure 4: a kind of high density calking sand control screen, it includes parent tube 1, on the tube wall circumference of this parent tube 1, be drilled with a plurality of oil-through holes 4, oil-through hole 4 is externally connected to calking cartridge filter 3 on parent tube 1, precision stamping has highdensity side direction seam 5 on the barrel circumference of calking cartridge filter 3, is connected with support ring 2 respectively at the two ends of calking cartridge filter 3.
Be drilled with the oil-through hole 4 that spiral distributes on the described parent tube 1 tube wall circumference, can effectively reduce body cross section perforated area, improved the bulk strength and the non-deformability of screen casing.Support ring 2 is welded at described calking cartridge filter 3 two ends respectively, and this support ring 2 is welded as a whole with parent tube 1.
The parent tube 1 of sand control screen adopts the tubing and casing that meets the API standard-required, its oil-through hole 4 is that fluid is by entering the passage of production flow line, highly dense calking cartridge filter 3 integral assemblings are on parent tube 1, calking cartridge filter 3 two ends are furnished with support ring 2, calking cartridge filter 3 welds together with support ring 2 earlier, and support ring 2 welds together with parent tube 1 again.Highly dense calking cartridge filter is welded after by precision stamping by corrosion resistant plate, and corrosion resistant plate forms highdensity side direction seam 5 through behind the precision stamping, and wide can accurately control of highdensity side direction seam 5 seams on the calking cartridge filter 3 reaches micron order.The side direction seam 5 of calking cartridge filter 3 can be to distribute along the body axis, also can be to distribute, adopt vertical masonry joint welding or spiral welding to make respectively, finally realize the oil catch Grains by side direction seam 5 along the body helix, change oily flow path direction simultaneously, reduce fluid directly washing away parent tube 1.
