Abstract
A kind of bearing type wellhead assembly of geothermal well.Mainly solve the problems, such as that existing geothermal well wellhead assembly load-bearing capacity is weak.It is characterized by: wellhead flange (1) top is bolted steering flange (2), the bolt hole on the steering flange (2) is strip hole in the circumferential direction, and central angle corresponding to strip hole is 30 °；Steering flange (2) top is connected with central tube (3), central tube (3) side is connected with import bend pipe (10), central tube (3) top is connected with upper flange (4), load-bearing flange (5) are bolted in upper flange (4) top, load-bearing flange (5) top is equipped with core pipe hanging head (6), core pipe hanging head (6) bottom is taken hot core pipe (11) by internal screw thread connection, and top passes through internal screw thread connection outlet bend pipe (8).The bearing type wellhead assembly of the geothermal well is adapted to different application environments, and load-bearing capacity is strong.
Description
Technical field
The utility model relates to geothermal energy developments to utilize device, the bearing type wellhead assembly of specifically a kind of geothermal well.
Background technique
Currently, taking hot mode using two kinds in shallow layer geothermal energy development and utilization: one is by recovery of subterranean thermal water resource
Reach and takes hot purpose；Another kind is to be reached by heat transferring medium circulation using heat not water-supply method is taken and take hot purpose.At second
It takes in hot mode, geothermal well takes hot core pipe to generally use plastic material, and plastic material has light weight, thermal coefficient low, resistance to
The low feature of hot temperature, but its corresponding wellhead assembly structure is too simple, and the core pipe that can be carried is small from weight.
Summary of the invention
In order to overcome the shortcomings of that existing geothermal well wellhead assembly load-bearing capacity is weak, the utility model provides a kind of geothermal well
Bearing type wellhead assembly, the bearing type wellhead assembly of the geothermal well is adapted to different application environments, and load-bearing capacity is strong.
The technical solution of the utility model is: a kind of bearing type wellhead assembly of geothermal well, including wellhead flange, takes hot core
Steering flange is bolted in pipe, the wellhead flange top, and the bolt hole on the steering flange is in the circumferential direction
Strip hole, and central angle corresponding to strip hole is 30 °；Steering flange top is connected with central tube, the central tube one
Side is connected with import bend pipe, and central tube top is connected with upper flange, and upper flange top is bolted load-bearing flange, holds
Weight flange top is equipped with core pipe hanging head, and core pipe hanging head bottom takes hot core pipe by internal screw thread connection, and top is connected by internal screw thread
Outlet elbow.
Angle between the import bend pipe and central tube is 45 °.
The utility model has the following beneficial effects: due to taking above scheme, upper flange top is connected with load-bearing method
Orchid, load-bearing flange top are equipped with core pipe hanging head, and load-bearing flange can accept the core pipe weight that core pipe hanging head transmits, to increase dress
The load-bearing capacity set, to adapt to different environment；Heat transferring medium is small to the lateral scouring for taking hot core pipe, reduces injection resistance and right
Take the disturbance of hot core pipe；And the device manufacturing, simple installation, convenient disassembly, stability is good, production cost and maintenance cost
It is low.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
1- wellhead flange in figure, 2- steering flange, 3- central tube, 4- upper flange, 5- load-bearing flange, 6- core pipe hanging head,
7- outlet(discharge) flange, 8- outlet elbow, 9- suction flange, 10- import bend pipe, 11- take hot core pipe.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing:
As shown in Figure 1, the bearing type wellhead assembly of a kind of geothermal well, including wellhead flange 1, take hot core pipe 11, the well
Steering flange 2 is bolted in 1 top of mouth flange, and the bolt hole on the steering flange 2 is strip hole in the circumferential direction,
And central angle corresponding to strip hole is 30 °, the connection direction of pipeline adjustable in this way and well head.On the steering flange 2
Portion is connected with central tube 3, and 3 side of central tube is connected with import bend pipe 10, between the import bend pipe 10 and central tube 3
Angle is 45 °, can improve lateral scouring of the heat transferring medium of injection to hot core pipe is taken, and reduces injection resistance and to taking hot core pipe
Disturbance.10 end of import bend pipe is connected with suction flange 9.3 top of central tube is connected with upper flange 4, upper flange 4
Load-bearing flange 5 is bolted in top, and 5 top of load-bearing flange is equipped with core pipe hanging head 6, and load-bearing flange 5 can accept core pipe extension
The first 6 core pipe weight transmitted, to increase the load-bearing capacity of device.6 bottom of core pipe hanging head takes heat by internal screw thread connection
Core pipe 11, top pass through internal screw thread connection outlet bend pipe 8,8 end connection outlet flange 7 of outlet elbow.
The device manufacturing, simple installation, convenient disassembly, stability are good；Heat transferring medium is small to the disturbance for taking hot core pipe；Production
Cost and maintenance cost are low；The wellhead assembly load-bearing capacity, bearing capacity is increased, allows to adapt to different environment.
