Abstract
The utility model relates to a pressure bearing rotating joint arranged at the lower end of a hydraulic pusher used in oil well measuring field, comprising a lower end manifold (1), a pressure bearing plug (2), a parallel bushing (3), a normal pressure socket (4), a swivel sleeve (5), a normal pressure plug (6) and a casing (7); wherein, the casing (7) is connected with the lower end manifold (1); the pressure bearing plug (2) is connected with the normal pressure socket (4); the parallel bushing (3) and the swivel sleeve (5) are respectively sleeved on the normal pressure socket (4); the swivel sleeve (5) is connected with the normal pressure plug (6) so as to effectively avoid the damage of the pressure bearing plug pin due to frequent connection between the underground instrument and the pusher and greatly reduce the possibility of damaging the underground instrument caused by the infiltration of the hydraulic oil and slurry due to the failure of the pressure bearing plug. In addition, the utility model has the advantages of simple structure, easy-dismounting and strong versatility.
Description
Technical field
The utility model relates to the lower end pressure-bearing adapter in a kind of hydraulic sidewall contact device that use in the oil well logging field, be used for being connected of hydraulic sidewall contact device and following end joint.
Background technology
Hydraulic sidewall contact device can satisfy the needs of logging instrument bore hole well loggings such as lithology and density logging, compensation density and focus type microballoon.Lower end pressure-bearing adapter is the structural member that hydraulic sidewall contact device is connected with following end instrument.Similarly the syndeton of hydraulic sidewall contact device in the lower end mostly adopted the direct form (seeing accompanying drawing 1) that is connected with following end instrument of pressure-bearing plug in the past.Need though this structure is compact that pressure-bearing plug performance is very reliable could to guarantee the instrument operate as normal.Frequently patch the damage that usually can cause pressure-bearing plug contact pin between following end instrument and the telescoping ram, in case and the pressure-bearing plug lost efficacy will make hydraulic oil in the hydraulic sidewall contact device even mud infiltrate down end instrument causes bigger destruction.
Through investigation and retrieval, at present domestic also do not have producer to improve at this problem that hydraulic sidewall contact device exists.
Summary of the invention
The purpose of this utility model is to provide a kind of hydraulic sidewall contact device lower end pressure-bearing adapter of a kind of oil well logging field use, can effectively avoid the generation of fault.
The utility model be achieved in that comprise lower end manifold 1, pressure-bearing plug 2, go forward side by side ring 3, normal pressure connector assembly 4, conversion sleeve 5, normal pressure plug 6, shell 7, shell 7 is connected with lower end manifold 1, pressure-bearing plug 2 is connected with normal pressure connector assembly 4, go forward side by side ring 3, conversion sleeve 5 is enclosed within respectively on the normal pressure connector assembly 4, conversion sleeve 5 is connected with normal pressure plug 6.
Pressure-bearing plug 2 is by also tightly encircling 3 axial location.
Advantage of the present utility model is: can effectively avoid because of the damage that frequently patches the pressure-bearing plug contact pin that causes between end instrument and the telescoping ram down, reduce because of the pressure-bearing plug loses efficacy making hydraulic oil and mud infiltration cause down the ruined possibility of end instrument greatly.The utility model is simple in structure simultaneously, convenient disassembly, highly versatile.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment
As shown in drawings, form by lower end manifold 1, pressure-bearing plug 2, the ring 3 of going forward side by side, normal pressure connector assembly 4, conversion sleeve 5, normal pressure plug 6, shell 7, shell 7 is connected with lower end manifold 1, pressure-bearing plug 2 is connected with normal pressure connector assembly 4, go forward side by side ring 3, conversion sleeve 5 is enclosed within respectively on the normal pressure connector assembly 4, conversion sleeve 5 is connected with normal pressure plug 6.
Pressure-bearing plug 2 can be realized finishing flexibly connecting function to inserting and separating with normal pressure connector assembly 4 in the pressure-bearing adapter of lower end.
The connector that normal pressure connector assembly 4, conversion sleeve 5, normal pressure plug 6 are formed in the pressure-bearing adapter of lower end is packed into from the right-hand member of shell 7.
The designed structure of the utility model can make lower end instrument and frequent the connection by normal pressure plug 6 between the hydraulic sidewall contact device finish, and has effectively avoided pressure-bearing plug 2 because of plugging the fault that occurs repeatedly, has improved reliability.
Pressure-bearing plug 2 is finished axial location by also tightly encircling 3 in the pressure-bearing adapter of lower end.
Pressure-bearing plug 2 is packed in the manifold 1 of upper end, and with and tightly encircle 3 axial restraints; Shell 7 is connected with upper end manifold 1; The connector that normal pressure connector assembly 4, conversion sleeve 5, normal pressure plug 6 are formed is packed into from the right-hand member of shell 7.
Claims (2)
1, a kind of hydraulic sidewall contact device lower end pressure-bearing adapter, comprise lower end manifold (1), pressure-bearing plug (2), the ring (3) of going forward side by side, normal pressure connector assembly (4), conversion sleeve (5), normal pressure plug (6), shell (7), it is characterized in that: shell (7) is connected with lower end manifold (1), pressure-bearing plug (2) is connected with normal pressure connector assembly (4), go forward side by side ring (3), conversion sleeve (5) is enclosed within respectively on the normal pressure connector assembly (4), and conversion sleeve (5) is connected with normal pressure plug 6.
