Abstract
A kind of communication pipe nipple of adjustable length is made up of communication interface, connection, expansion link, interior bar, sliding ring and urceolus, expansion link and urceolus install sliding ring respectively, expansion link penetrates urceolus, interior bar to penetrate in expansion link and with urceolus screwed tight, connection passes from interior bar, welds with the communication interface at two ends.Expansion link adopts slipper seal structure, adjustable length.Order wire connects the communication interface at two ends, realizes communication function.The utility model length can regulate, easy to use, and uniaxial direct tensile or pressure texture part can realize, and structural member easy maintenance, be applicable to the well of various sizes, high to the safeguard protection reliability of wireless drilling inclinometers (MWD).
Description
Technical field
The utility model relates to oil, colliery and geological prospecting drilling engineering deviational survey field, is specifically related to a kind of communication pipe nipple of adjustable length.
Background technology
Along with wellbore construction is more and more darker, in order to ensure the safety of constructing, prevent the generation of the accident such as bit freezing, fish, underground engineering parameter is increased gradually by attitude parameter under traditional measuring well according to customer demand wireless drilling inclinometers (MWD), as: the parameter such as moment of torsion, the pressure of the drill, interior annular pressure, outer annular pressure, rotating speed, vibration, wireless drilling inclinometers (MWD) is more and more important as the instrumentality of underground engineering parameter measurement and transmission.After increasing engineering parameter function, require very high to wireless drilling inclinometers (MWD) installation site, because engineering parameter pipe nipple must be connected with the non magnetic drill collar of client, MWD is very accurate at non magnetic drill collar intermediate demand relative position, but the non magnetic drill collar that customers' place uses often size differs, what have reprocessed, so bad location, the communication pipe nipple of length so just can be regulated in the urgent need to one, accurate to guarantee the position of wireless drilling inclinometers and drill collar, the communication pipe nipple of adjustable length faces the problem of slipper seal simultaneously, higher than normal static seal difficulty a lot, especially in the adverse circumstances of down-hole HTHP, sealing reliability is just difficult to realize more.
Summary of the invention
In order to solve adjustable length and the slipper seal problem of wireless drilling inclinometers, the utility model provides a kind of communication pipe nipple of adjustable length, guarantees adjustable length by movable sealing structure, and realizes proper communication function.
The technical scheme that its technical problem of the novel solution of the utility model adopts is: a kind of communication pipe nipple of adjustable length is made up of communication interface, connection, expansion link, interior bar, sliding ring and urceolus, expansion link and urceolus install sliding ring respectively, expansion link penetrates urceolus, interior bar to penetrate in expansion link and with urceolus screwed tight, connection passes from interior bar, welds with the communication interface at two ends.Expansion link adopts slipper seal structure, adjustable length.Order wire connects the communication interface at two ends, realizes communication function.
The beneficial effects of the utility model are, length can regulate, easy to use, and uniaxial direct tensile or pressure texture part can realize, and structural member easy maintenance, be applicable to the well of various sizes, high to the safeguard protection reliability of wireless drilling inclinometers (MWD).
Accompanying drawing explanation
Below in conjunction with drawings and embodiments, the utility model is further illustrated.
Fig. 1 is a kind of structural representation of communication pipe nipple of adjustable length.
Fig. 2 is a kind of schematic appearance of communication pipe nipple elongation length of adjustable length.
Fig. 3 is the schematic appearance that a kind of communication pipe nipple of adjustable length reduces length.
In figure: bar, 5 order wires, 6 communication interfaces in 1 expansion link, 2 urceolus, 3 sliding rings, 4.
Detailed description of the invention
As shown in Figure 1, expansion link (1) and urceolus (2) are loaded onto sliding ring (3) respectively, expansion link (1) is penetrated in urceolus (2), then interior bar (4) is penetrated in expansion link (1), and with urceolus (2) screwed tight, again order wire (5) is passed from interior bar (4), afterwards order wire (5) is welded wiring with the communication interface (6) at two ends.Expansion link, urceolus and interior bar are the main parts of this device Collapsible structure, adopt slip two way seal technology, namely urceolus and expansion link, all adopt slipper seal between expansion link and inner core, wherein sliding ring is arranged on expansion link and urceolus respectively.The Extensible scope of this pipe nipple is 250mm, and connection passes from interior bar, and two ends connect communication interface respectively, and order wire is helical wire form, guarantees in the process stretched and shorten, and order wire can not be damaged by pulling.As shown in Figure 2, after the communication pipe nipple of adjustable length has been assembled, elongate the schematic appearance of length.As shown in Figure 3, the communication pipe nipple of adjustable length reduces the schematic appearance of length after having assembled.
More than realize a method of the present utility model, based on other way of realization of this utility model principle within scope of the present utility model.
Claims (2)
1. the communication pipe nipple of an adjustable length, it is characterized in that: be made up of communication interface, connection, expansion link, interior bar, sliding ring, urceolus, expansion link and urceolus install sliding ring respectively, expansion link penetrates urceolus, interior bar to penetrate in expansion link and with urceolus screwed tight, connection passes from interior bar, welds with the communication interface at two ends.
2. the communication pipe nipple of adjustable length according to claim 1, is characterized in that: expansion link adopts slipper seal structure, adjustable length.
