Abstract
The utility model relates to a geothermal well pipe having a cable protection function. The geothermal well pipe comprises a well pipe body; flanges are respectively welded at the two ends of the well pipe; and connecting holes are uniformly distributed at the flanges. The geothermal well pipe is characterized in that a cable device is fixedly arranged at the outer wall of the portion, between the flanges at the two ends, of the well pipe. The cable device includes a cable; a male plug and female plug are arranged at the two ends of the cable and are plugged into installing holes of the flanges at the two ends; the peripheral portions of the male and female plugs are filled with a temperature-resistant oil-resistant insulator for fixing the male and female plugs; and rubber sealing rings are respectively arranged at the two ends of the insulator. Besides, a plurality of fixing components for clamping and fixing the cable are arranged at the outer surface of the well pipe. According to the structure, the cable and the geothermal well pipe are arranged into an integrated structure; and the cable is in a butt joint following the well pipe by one-time operation during the well-logging well pipe connection process, thereby realizing convenience and rapidity. Therefore, a problem of cable wearing of a submersible pump due to frequent friction between the cable and the well wall during well-logging process of the submersible pump can be solved. In addition, the provided geothermal well pipe has the advantages of simple structure, reasonable design, and easy manufacturing and the like.
Description
Technical field
The utility model belongs to the geothermal well-pipe technical field, particularly relates to a kind of geothermal well-pipe with protection cable feature.
Background technology
While working due to the geothermal well immersible pump, need to invade bubble in GEOTHERMAL WATER, so just make submersible pump cable for a long time in high temperature, in the GEOTHERMAL WATER of highly corrosive, through the long-term bubble of invading, crackle appears in the accelerated ageing of cable surface insulating barrier, makes its lost of life; Usually the water level of hot well is-100 meters left and right, well casing is generally at 6 meters one section, so just need 20 more piece well casing guarantees that water level and the coupling of adopting discharge are arranged, usually immersible pump is connected with well casing, and be arranged on the lowermost end of well casing, submersible pump cable just draws up along the well casing colligation, will be through more than 20 ring flange junctions, because the well casing ring flange is more much bigger than well casing diameter, add cable and pass through in the ring flange periphery again, when immersible pump is gone into the well, frequent and wall friction, perhaps, due to staff's misoperation, very easily because of mechanical force, damage cable; Cause submersible pump cable to damage phenomenon.
Summary of the invention
The utility model for solve the technical problem existed in known technology provide a kind of simple in structure, easy to install, prevent the cable wearing and tearing, improve the geothermal well-pipe with protection cable feature of lower well operations.
The technical scheme that the utility model is taked for the technical problem existed in the solution known technology is:
A kind of geothermal well-pipe with protection cable feature, the two ends that comprise well casing, well casing are welded with respectively flange, flange is provided with and is laid with connecting hole, it is characterized in that: between the flange at described two ends, on the well casing outer wall, be fixed with cable installation, described cable installation comprises cable, the two ends of cable are provided with the male and female plug, described male and female plug is inserted in the installing hole of two end flanges, the periphery of male and female plug is filled with the fixedly heatproof oil resistant insulating body of male and female plug, and the two ends of described insulator are respectively equipped with rubber seal; The outer surface of described well casing is provided with several for clamping the fixed component of fixed cable.
The utility model can also adopt following technical measures:
Described fixed component comprises the connecting portion be connected with geothermal well-pipe, and the outer end of described connecting portion is provided with cable and clamps section, and the inner surface that described cable clamps section is provided with protective jacket.
The described cable section of clamping adopts Split type structure, and fixedly split body and movable split body are arranged, and after two lobe bodies connect to form by connector, its inner chamber is consistent with the exterior cross-section of cable.
Described connector is bolt, and described cable clamps the fixedly split body of section and the two ends of movable split body are bolted.
Described connector is jointed shaft, and the fixedly split body that described cable clamps section is connected by jointed shaft with movable split body one end, and the other end adopts bolt or padlock.
Described cable adopts waterproof bus.
Advantage and the good effect that the utlity model has are: because the utility model adopts technique scheme, cable and geothermal well-pipe are fabricated to integrative-structure, in the connection well casing process of going into the well, cable has once docked with well casing, convenient quick, thereby avoided when immersible pump is gone into the well, cable often and wall friction, thereby solved the problem of submersible pump cable wearing and tearing.In addition, in order to prevent electric leakage, the periphery of male and female plug is filled with the fixedly heatproof oil resistant insulating body of male and female plug, at the two ends of insulator, is respectively equipped with rubber seal; In order to guarantee that cable is more firm, the outer surface of well casing is provided with several for clamping the fixed component of fixed cable.Therefore the utlity model has the function of stronger protection cable, but also improve the operating efficiency of going into the well, reduce the intensity of having worked, in addition the utility model also have simple in structure, reasonable in design, be easy to processing and manufacture, be convenient to the advantage such as transportation.
