Description

Combined type oil exploitation stabilizing catheter
Technical field
It the utility model is related to technical field of petroleum extraction, and in particular to combined type oil exploitation stabilizing catheter.
Background technology
During oil exploitation, it is exactly well hole downcomer of laying foundation first, fixative is filled between conduit and the borehole wall Conduit is set to be fixed with the borehole wall;Then unnecessary conduit is cut, the upper surface and basic well opening for making conduit are generally aligned in the same plane, then In conduit upper surface mounting seat.In the prior art, during cutting catheter, conduit can be by radial direction shaking force so that Loosened between conduit and the borehole wall, influence the stability of the oil recovery device of subsequent installation.Further, since Jing Dong is more narrow and small, cutting During need more people's compounding practices, increase the cutting difficulty of conduit;Meanwhile the unnecessary conduit being cut off is often also direct As waste material, the waste of resource is caused.
Utility model content
The purpose of this utility model is to provide combined type oil exploitation stabilizing catheter solve to lead using prior art installation The mode of pipe exist conduit installation stability it is poor, cutting difficulty greatly, easily cause the problem of wasting of resources.
The utility model is achieved through the following technical solutions:
Combined type oil exploitation stabilizing catheter, including body, the body include several sockets, one end of each socket An annular groove is provided with end face, a cylindrical connector is provided with other end end face, in the annular groove Heart line is overlapped with the center line of socket, and the cylindrical connector is mutually matched with annular groove, and the inwall of annular groove and Screw thread is provided with the outer wall of cylindrical connector.Further, the utility model is improved to existing conduit, design A kind of packaging conduit, the conduit is mutually spliced by several sockets to be formed, the axial length of socket can be arbitrarily changeable, The both ends of each socket are respectively cylindrical connector and annular groove, when two sockets assemble, using installation tool by one 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.
