The cylindrical connector of socket is put into the groove of another socket, and rotational fastener, two sockets is connected as an entirety.
In practical operation, height, the quantity of the socket of installation can be selected according to Jing Dong depth, meets leading after just installing
The upper surface of pipe is generally aligned in the same plane with basic well opening;The utility model transfers to the body being made up of multiple sockets
After Jing Dong, fixative is then filled between conduit and the borehole wall again, without being cut to the conduit after fixation, ensure that installation
Conduit stability, it also avoid waste tube material the problem of.
Preferably, the socket, which is provided with the end face of annular groove, is also provided with an O-ring seal standing groove, the O
The outside that type sealing ring standing groove is close to annular groove is set.Further, O-shaped sealing is placed in O-ring seal standing groove
Circle, the both ends of O-ring seal contact simultaneously with the end face of two sockets respectively, at the same its madial wall also with cylindrical connector
Lateral wall contacts, and forms the sealing structure in three directions;Also, when in two socket installation processes, O-ring seal can be by
One axial compressive force, so as to produce radial direction deformation, make two socket expansion connections, further ensure the sealing of two sockets
And connective stability, it is difficult for drop-off.
Preferably, several scrobicular rings are also provided with the side wall of the socket, the scrobicular ring is uniformly arranged along the axial direction of socket,
Each center line of scrobicular ring overlaps with the center line of socket.Further, conduit lateral wall of the prior art is smooth surface,
It is relatively low to the adhesive force of fixative so that conduit, which is given a shock, to be easy for departing from fixative.The utility model is in the side of socket
Wall opens several scrobicular rings, that is, the circumferential direction recessing along socket.Multiple scrobicular rings are set to not only increase socket with consolidating
Determine the contact area of agent, while the wall of scrobicular ring inwall adds the adhesive force to fixative;In addition, in follow-up oil recovery device
In installation process, conduit can be by axial compressive force, and the fixative contained is stung in scrobicular ring can produce radially in the presence of axial compressive force
Deformation, a radial compression power is applied simultaneously to conduit and the borehole wall so that what is connected between conduit and well hole is closer, ensure that
The support strength of conduit.
Preferably, the cylindrical connector is integrally formed with socket.Be integrally formed the cylindrical connector of finger is with socket
It is process by a cylinder, is integrally formed the intensity for ensureing the utility model connection.
The utility model compared with prior art, has the following advantages and advantages:
1st, the utility model combined type oil exploitation stabilizing catheter, including body, the body include several sockets, often
An annular groove is provided with one end end face of individual socket, is provided with a cylindrical connector, socket on other end end face
Axial length can be arbitrarily changeable, the both ends of each socket are respectively cylindrical connector and annular groove, two sockets assemblings
When, the cylindrical connector of one socket is put into the groove of another socket using installation tool, and rotational fastener, make two
Individual socket is connected as an entirety;Conduit installation be present by way of above structure solves and installs conduit using prior art
Stability it is poor, cutting difficulty is big, easily causes the problem of wasting of resources;
2nd, the utility model combined type oil exploitation stabilizing catheter, O-ring seal is placed in O-ring seal standing groove,
The sealing and connective stability of two sockets are ensure that, it is difficult for drop-off;
3rd, the utility model combined type oil exploitation stabilizing catheter, several scrobicular rings are also provided with the side wall of the socket,
The scrobicular ring is uniformly arranged along the axial direction of socket, and the center line of each scrobicular ring overlaps with the center line of socket, and above structure is not only
The contact area of socket and fixative is added, improves the adhesive force to fixative, while can make when producing radial direction deformation
What must be connected between conduit and well hole is closer, ensure that the support strength of conduit.
