Abstract
The utility model relates to a connection device for a drilling measurement system down-hole instrument. In order to overcome the deficiencies that the erosion can easily occur to the main body of the connection device of the prior drilling measurement system down-hole instrument, the connection between a buffer and the main body can not be disassembled, the service life is short and the cost is high. The connection device is composed of a multi-stage connector I (1), a main body (4), a buffer (6), a transition connector (7) and a multi-stage connector II (8) which are connected from the bottom to the top in sequence; a centralizer (2) is fixedly installed on the ex-circle surface of the main body (4); the diameter of the position of the main body (4) at which the centralizer (2) is installed is identical to the diameter of both ends; the upper end part of the buffer (7) is inserted into the inner hole of the lower end part of the main body (4) and fixedly connected through fixing screws (5). The connection device has the advantages that the structure is reasonable, the connection device is erosion resistant, the maintenance is convenient, the service life is long, and the cost is reduced.
Description
Affiliated technical field
The utility model relates to a kind of measurement-while-drilling system downhole instrument, especially relates to a kind of measurement-while-drilling system downhole instrument linkage.
Background technology
At present, use measurement while-drilling instrument and measure in the directional well drilling engineering, the effect of downhole instrument linkage is to connect impulse generator, power module, coil drive module, memory module, orientation survey module, gamma survey module etc. according to the operation needs in the measurement while-drilling instrument; Centralizer on the body has the cushioning effect of setting upright, and wiper block mostly is the rubber material, has anti-washing away, the advantage of long service life.At present, downhole instrument linkage structure is installed the body position employing reducing design of rubber centralizer as shown in Figure 1, this structure makes mud easily form eddy current at the centralizer place, body reduces application life easily by erosion, influences the work of measurement-while-drilling system downhole instrument complete machine; Snubber adopts with body and is threaded, and by the locking pin location, non-dismountable, when the impaired cisco unity malfunction of downhole instrument linkage individual component, will integral body scrap, use cost improves.
Summary of the invention
In order to overcome body that existing measurement-while-drilling system downhole instrument linkage exists easily by erosion, snubber is non-dismountable with being connected of body, the deficiency that application life is short, cost is high, and the utility model provides a kind of measurement-while-drilling system downhole instrument linkage.
The technical scheme that its technical problem that solves the utility model adopts is: measurement-while-drilling system downhole instrument linkage, comprise multi-stage connector I, body, snubber, transit joint, multi-stage connector II, and multi-stage connector I, body, snubber, transit joint, multi-stage connector II connect successively, be installed with centralizer on the outer round surface of body, it is identical with the both ends diameter that centralizer place diameter is installed on the body; Insert in the endoporus of body bottom the snubber upper end, fixedly connected by hold-down screw.
The beneficial effects of the utility model are, and are rational in infrastructure, erosion resistance, long service life; Be convenient to maintenance, reduce use cost.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is known measurement-while-drilling system downhole instrument linkage structural representation.
Fig. 2 is the A-A view of Fig. 1
Fig. 3 is the utility model measurement-while-drilling system downhole instrument linkage structural representation.
Fig. 4 is the B-B view of Fig. 3.
Among the figure: 1. multi-stage connector I, 2. centralizer, 3. hold-down screw, 4. body, 5. hold-down screw, 6. snubber, 7. transit joint, 8. multi-stage connector II.
The specific embodiment
The utility model measurement-while-drilling system downhole instrument linkage, comprise multi-stage connector I 1, body 4, snubber 6, transit joint 7, multi-stage connector II 8, and multi-stage connector I 1, body 4, snubber 6, transit joint 7, multi-stage connector II 8 from top to bottom connect successively, be installed with centralizer 2 on the outer round surface of body 4, centralizer 2 is by on the hold-down screw 3 hard-wired bodies 4.It is identical with the both ends diameter that centralizer 2 place's diameters are installed, and rubber centralizer place slurry channel is fabricated to latus rectum, avoids installing the generation of centralizer 2 place's vortex phenomenon, reduces body 4 and damaged the application life of raising device by erosion.
Fixedly connected with transit joint 7 in the lower end of snubber 7; Insert in the endoporus of body 4 bottoms the upper end of snubber 7, is generally matched in clearance, and fixedly connected by hold-down screw 5, when snubber 7 or body 4 parts are damaged, can carry out maintain and replace easily, avoid scrapping of whole device, effectively reduce cost.
Claims (1)
1. measurement-while-drilling system downhole instrument linkage, comprise multi-stage connector I, body, snubber, transit joint, multi-stage connector II, and multi-stage connector I, body, snubber, transit joint, multi-stage connector II from top to bottom connect successively, be installed with centralizer on the outer round surface of body, it is characterized in that: the diameter that body (4) last installation centralizer (2) is located is identical with the both ends diameter; Insert in the endoporus of body (4) bottom snubber (7) upper end, fixedly connected by hold-down screw (5).
