The utility model relates to an use the sleeve pipe in the pit, specifically provide a glass steel is sleeve pipe in pit, including many FRP pipe ways, connect through the coupling between adjacent FRP pipe says, FRP pipe says that the both ends outer wall respectively is equipped with the external screw thread, the coupling inner wall be equipped with with external screw thread assorted internal thread, the tip that adjacent FRP pipe said offsets in the coupling and is sealed through sealed rubber ring between the two, FRP pipe says and to include by outer to the interior external coating who bonds in proper order, twine layer strengthening rib layer and corrosion -resistant layer outward. The utility model provides a glass steel is sleeve pipe in pit, simple structure, it is good to connect the leakproofness, and shock resistance is strong, and compression strength is high, and is corrosion -resistant and wear -resisting, and long service life practices thrift the cost, has extensive application prospect.
Description
Technical field
This utility model relates to a kind of down-hole sleeve pipe, is specifically related to a kind of glass fiber reinforced plastic well setting of casing.
Background technology
Known oil field well glass reinforced plastic pipe is the most studied and applies decades, fiber fw frp high-pressure oil pipe and oil well casing production line are introduced in early days, pipe employing is threaded is exclusively used in petroleum industry, China Petroleum almost all uses steel conduit, decay resistance is poor, its pipe corrosion speed, also can only be in three to five years after a bite oil well formula water flooding well pipe preservative treatment, glass reinforced plastic pipe corrosion resistance is preferable relative to steel pipe, service life, service life was 4-5 times of steel pipe life-span between 15-20.But, along with the development of technology, in use there is some problems in existing glass reinforced plastic pipe, such as, mechanical performance is the strongest；Connection sealing between glass reinforced plastic pipe is poor, causes pipe leakage；Major part fiberglass compressive resistance is low and shock resistance is weak.
Utility model content
The purpose of this utility model is the defect overcoming above-mentioned prior art, it is provided that a kind of connection sealing can good, compressive resistance is high and strong shock resistance and cost-effective glass fiber reinforced plastic well setting of casing.
For this, this utility model provides a kind of glass fiber reinforced plastic well setting of casing, including many GRP pipes, connected by box cupling between adjacent glass steel conduit, GRP pipe two ends outer wall is respectively provided with external screw thread, box cupling inwall is provided with the female thread matched with external screw thread, and the end of adjacent glass steel conduit is offseted in box cupling and sealed by O-ring seal between the two；
Described GRP pipe includes external protection, outer wrap, reinforcement layer and the anti-corrosion layer bondd the most successively.GRP pipe compressive resistance is high, strong shock resistance.Improve the corrosion resistance of GRP pipe.
GRP pipe in this utility model is connected by box cupling, and box cupling uses with GRP pipe and threadeds, and between GRP pipe, use O-ring seal end seal, first GRP pipe one end is screwed in box cupling, again O-ring seal is put into box cupling, then by another GRP pipe screw-in box cupling until propping up previous GRP pipe, two GRP pipes by O-ring seal compression thus reach sealing purpose.
As preferably, described external screw thread and female thread all use trapezoidal thread.
As preferably, described outer wrap is the composite bed being composited with epoxy resin substrate with the winding angle of 55 °-65 ° by reinforced plastic glass fibre.
As preferably, described external protection is corrugated tube.
As preferably, described reinforcement layer includes many reinforcements.
The beneficial effects of the utility model: this glass fiber reinforced plastic well setting of casing that this utility model provides, simple in construction, connection sealing is good, strong shock resistance, and compressive resistance is high, and erosion and wear resistant, service life is long, cost-effective, has wide application prospect.

Detailed description of the invention
Below in conjunction with the accompanying drawings and detailed description of the invention, it is further elucidated with this utility model.
Embodiment 1:
A kind of glass fiber reinforced plastic well setting of casing as shown in Figure 1,2 and 3, including many GRP pipes 1, connected by box cupling 2 between adjacent glass steel conduit 1, GRP pipe 1 two ends outer wall is respectively provided with external screw thread 4, box cupling 2 inwall is provided with the female thread 5 matched with external screw thread 4, and the end of adjacent glass steel conduit 1 is offseted in box cupling 2 and sealed by O-ring seal 3 between the two；Described external screw thread 4 all uses trapezoidal thread with female thread 5.
As shown in Figure 4, GRP pipe 1 includes external protection 1.1, outer wrap 1.2, reinforcement layer 1.3 and the anti-corrosion layer 1.4 bondd the most successively.GRP pipe 1 compressive resistance is high, strong shock resistance.Described outer wrap 1.2 is the composite bed being composited with epoxy resin substrate with the winding angle of 55 °-65 ° by reinforced plastic glass fibre.Described external protection 1.1 is corrugated tube.Described reinforcement layer 1.4 includes many reinforcements.
GRP pipe 1 in this utility model is connected by box cupling 2, and box cupling 2 uses with GRP pipe 1 and threadeds, and between GRP pipe 1, use O-ring seal end seal, first GRP pipe 1 one end is screwed in box cupling 2, again O-ring seal 3 is put into box cupling 2, then another GRP pipe 1 being screwed in box cupling 2 until propping up previous GRP pipe 1, O-ring seal 3 is compressed thus reaches sealing purpose by two GRP pipes 1.
This glass fiber reinforced plastic well setting of casing that this utility model provides, simple in construction, connection sealing is good, strong shock resistance, and compressive resistance is high, and erosion and wear resistant, service life is long, cost-effective, has wide application prospect.
Exemplified as above is only to illustration of the present utility model, is not intended that the restriction to protection domain of the present utility model, within the every and same or analogous design of this utility model belongs to protection scope of the present invention.
