Abstract
The utility model relates to a corrugated stainless steel plate sand-proof pipe applied to oilfield drilling and extraction, which comprises an inner pipe and a stainless steel plate filtration net. A round hole is drilled on the inner pipe; the stainless steel plate filtration net is pressed into a corrugated cylindrical pipe, both ends of which are provided with sealed fixing joints with interpolation teeth; the corrugated cylindrical pipe has a sealed inserted-connection with the sealed fixed joints; both ends of the inner pipe drilled with a round hole are connected with the sealed fixed joints. The benefits are that the stainless steel plate filtration net is suppressed to a corrugated shape with the same thickness of the stainless steel plate, but the strength is increased, without deformation under pressure. A long gas is arranged between the stainless steel plate filtration net and the inner pipe with a round hole, so that the whole filtration net has the effect of oil filtration, improving the oil filtration rate. Besides, the utility model eliminates the outer pipe of the traditional sand anchor, thus is light in weight and good in oil filtration effect.
Description
Technical field
The utility model relates to a kind of oil field drilling sand control corrugated stainless steel plate mesh sand control tube that is applied to.
Background technology
Normally used screen pack on the sand anchor of oil field drilling operation traditional approach sand control; be to work out with metal or nonmetal monofilament; filter mesh deforms under the effect of pressure and loses shape; mesh is inhomogeneous; poor filtration effect; mesh deforms under the effect of pressure and loses shape; and; comprise interior pipe from structure; the spy purchases the sand material; screen pack; multiple filtration and protection ways such as outer tube; thereby increased sand anchor weight; patent of invention that the inventor herein has applied for (patent No. 00110474.8) " preparation technology of stainless steel board filter screen " and utility model patent (patent No. 01207068.8) " tubular stainless steel board filter screen sand anchor "; though solved the hole shape of screen pack; be out of shape after the pitch-row pressure-bearing; the problem of losing shape; but the tubular stainless steel board filter screen contacts with the interior pipe that is drilled with circular hole, and interior pipe drill hole can be oily excessively, does not have the drill hole can not be oily excessively; so; it is low to cross oily rate, and tubular stainless steel board filter screen thickness is little, and intensity is low.
Summary of the invention
The purpose of this utility model provides the oily rate height of a kind of mistake, intensity height, without the corrugated stainless steel plate mesh sand control tube of outer tube.
The utility model is achieved in that
A kind of corrugated stainless steel plate mesh sand control tube, pipe 5 and stainless steel board filter screen 2 double-layer structures in comprising, be drilled with circular hole on the interior pipe 5, stainless steel board filter screen 2 is pressed into the corrugated cylindrical tube, there is sealing and fixing joint 1 at corrugated cylindrical tube stainless steel board filter screen 2 two ends, sealing and fixing joint 1 has the interpolation tooth, and corrugated cylindrical tube stainless steel board filter screen 2 is pegged graft with 1 sealing of sealing and fixing joint, and interior pipe 5 two ends that are drilled with circular hole are connected with sealing and fixing joint 1.
Above-mentioned corrugated stainless steel plate mesh sand control tube, corrugated cylindrical tube stainless steel board filter screen 2 inboards are provided with fixed support ring 4.
Above-mentioned corrugated stainless steel plate mesh sand control tube, corrugated cylindrical tube stainless steel board filter screen 2 is to link together more than two sections or two sections, connects the back between two sections and is provided with protection ring 3 in the junction.
Benefit of the present utility model is:
Stainless steel board filter screen is pressed into corrugated, same corrosion resistant plate thickness, and intensity increases, and is indeformable after the pressure-bearing, keeps the shape.And stainless steel board filter screen and be drilled with between the interior pipe of circular hole rectangular gap is arranged, whole screen pack all plays the oil strain effect, crosses oily rate and improves, and saves the outer tube of traditional sand anchor, and in light weight, oil strain is effective.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is further specified
As Fig. 1, shown in 2, a kind of corrugated stainless steel plate mesh sand control tube, pipe 5 and stainless steel board filter screen 2 double-layer structures in comprising, be drilled with circular hole on the interior pipe 5, stainless steel board filter screen 2 is pressed into the corrugated cylindrical tube, same corrosion resistant plate thickness, intensity increases, stainless steel board filter screen and be drilled with between the interior pipe of circular hole rectangular gap is arranged, whole screen pack all plays the oil strain effect, cross oily rate and improve, there is sealing and fixing joint 1 at corrugated cylindrical tube stainless steel board filter screen 2 two ends, and sealing and fixing joint 1 has the interpolation tooth, corrugated cylindrical tube stainless steel board filter screen 2 is pegged graft with 1 sealing of sealing and fixing joint, interior pipe 5 two ends that are drilled with circular hole are connected with sealing and fixing joint 1, save the outer tube of traditional sand anchor, and are in light weight.In order to increase corrugated cylindrical tube stainless steel board filter screen 2 intensity, can be provided with fixed support ring 4 in corrugated cylindrical tube stainless steel board filter screen 2 inboards.
When corrugated cylindrical tube stainless steel board filter screen 2 was longer, corrugated cylindrical tube stainless steel board filter screen 2 was to link together more than two sections or two sections, connected the back between two sections and was provided with protection ring 3 in the junction, in case collide with, screen pack damages.
