Abstract
The utility model discloses a downhole instrument through line routing device, which comprises a skeleton, a lower joint, and a pressure bearing pipe of a logging instrument. The lower end of the skeleton is connected with the lower joint; two ends of the pressure bearing pipe are connected to the insides of the upper end portion and the lower joint of the skeleton respectively; the pressure bearing pipe is embedded inside a groove on the outer surface of the skeleton; the lower joint is connected with the skeleton via a threaded sleeve sleeved therebetween; the outer side of the threaded sleeve is provided with a screw thread matched with the inner screw thread at the lower end of the skeleton; the threaded sleeve props against and pushes the lower joint via a combined type semi-circular stop block embedded in the outer surface of the lower joint; a guiding structure being parallel to the axial direction is arranged between the lower joint and the lower end of the skeleton, and the connection part of the pressure bearing pipe and the lower joint is parallel to the lower joint axially. The pressure bearing pipe of the downhole instrument through line routing device is simple and convenient to install, since the middle part is free of an adapter, the structure is simplified and the occupied space is small; the pressure bearing pipe and the lower joint perform the rectilinear movement only when being connected, and the installation of the pressure bearing pipe can be completed while installing the lower joint.
Description
Technical field
The utility model relates to the technical field of oil downhole instrument, particularly relates to a kind of downhole instrument through track routing device.
Background technology
The downhole instrument space is limited, compact conformation, and work under bad environment, the routing problem of its through track is perplexing the structural engineer in this field always; In most of downhole instrument, the wiring of through track generally realizes by following four kinds of modes at present:
1. central tube uses the restriction of central tube cabling very big, can not the mounting center pipe in a lot of structures;
2. sealing-plug switching is used the sealing-plug cabling to be easy to cause Insulation Problems, and enough too much sealing-plugs of space mounting can not be provided in the instrument;
3. outside pressure-bearing hard tube because the shape of pressure-bearing pipe is irregular, is difficult to install, generally all be the pressure-bearing pipe disconnected be two sections or multistage, the centre installs adapter additional and realizes installing, adapter is wasting space relatively, hidden danger is also bigger;
4. oil-filled high-pressure hose owing to need the careful oil circuit of handling, realizes that difficulty is big, the structure more complicated.
The utility model content
The utility model is on the basis of externally pressure-bearing hard tube, proposes a kind of downhole instrument through track routing device, to solve the problem that the pressure-bearing pipe is difficult to install.
The technical solution of the utility model is: a kind of downhole instrument through track routing device, the skeleton that contains logger, lower contact, the pressure-bearing pipe, the lower end of described skeleton connects lower contact, described pressure-bearing pipe two ends are communicated in the upper end of skeleton respectively and in the lower contact, described pressure-bearing pipe is embedded in the groove of external surface of skeleton, described lower contact is connected by the swivel nut that is sleeved between the two with skeleton, this swivel nut outside is provided with the internal thread coupling of screw thread and skeleton lower end, described swivel nut is by embedding the combined semi collar stop pushing tow lower contact of lower contact external surface, be provided with guide frame, the connecting portion of described pressure-bearing pipe and lower contact and described lower contact axially parallel between described lower contact and the skeleton lower end with axially parallel.
The two ends of described pressure-bearing pipe are respectively equipped with adapter, and this adapter inserts respectively in skeleton upper end and the lower contact, and insert in this adapter at the two ends of described pressure-bearing pipe.
Be respectively equipped with the sealing ring of coupling inside and outside the described adapter.
Described collar stop is set with snap ring.
Described collar stop has two groups, is block A and block B, and block A edge is provided with step and is absorbed in and contacts with swivel nut in the swivel nut, is set with snap ring on the described block B.
Described guiding mechanism comprises the gathering sill of the coupling that lays respectively at skeleton lower end inner surface and lower contact external surface and is installed in the interior gib block of this gathering sill.
The external diameter greater than described combined semi collar stop of the diameter of the externally threaded place circle of described swivel nut.
The beneficial effects of the utility model
Pressure-bearing pipe simple installation of the present utility model, the centre does not have crossover sub, designs simplification, space hold is little, only does rectilinear motion during being connected of pressure-bearing pipe and lower contact and gets final product, and can finish the installation of pressure-bearing pipe when lower contact is installed.
The guiding mechanism of this utility model has guaranteed the straight-line directionality in the lower contact installation process, and the cooperation of suit and collar stop by swivel nut has realized circular motion to straight-line conversion, thereby has realized the rectilinear motion to lower contact.
