Description
Technical field
The utility model relates to oilfield drilling technology, is specifically related to a kind of for the structure with brill gyrolevel inserting tube antivibration.
Background technology
Along with the growing tension of world petroleum resource, offshore oilfield cluster well development efficiency requires more and more higher, in cluster well drilling well, the accurate measurement of well track more and more demonstrates its importance, and this just needs high-precision oil well with brill gyrolevel (for high-acruracy survey in sleeve pipe or drill string).At sea in cluster well (particularly high density cluster well, clump formula infill well etc.) drilling process, because institute's drilling well eye and adjacent well spacing may be less than 1 meter, offset well sleeve pipe produces magnetic interference, and traditional While drilling system based on Magnetic Measurement cannot normally use.In particular, with in the brill gyrolevel course of work, very large vibration can be produced, cause it normally to work.At present, the vibration proof structure of practical application all can not reach gratifying effect, and therefore, those skilled in the art are in the urgent need to a kind of vibration proof structure be applied to boring gyrolevel playing damping effect that can be good.
Utility model content
For solving the problem, the purpose of this utility model is to provide a kind of for the structure of boring gyrolevel inserting tube antivibration, can make better to be used under the working environment of high strength, large impact with brill gyrolevel.
For achieving the above object, the technical scheme that the utility model is taked is:
For the structure with brill gyrolevel inserting tube antivibration, comprising:
One inserting tube core;
One end of described inserting tube core connects a damping means;
The other end of described inserting tube core connects a rubber spring;
Described inserting tube core is placed in a compression tube;
Described inserting tube core disposed outside has the some annular dampener fitted tightly with compression tube inwall.
Further, described annular dampener is selected from one or both in O type rubber ring or flower pattern rubber ring.
Further, the quantity of described annular dampener is 6 ~ 12.
Further, described inserting tube core comprises an inserting tube structure, and also comprise the gear, optical fibre gyro, the Jia Biao that connect successively and fixedly add the dial framework of table, rear four are placed in inserting tube structure.
Further, the circuit board rubber seal of described optical fibre gyro, diameter dimension is 58mm, and inside is provided with trip bolt.
Further, described inserting tube core also comprises an electronics storehouse, and its inside is provided with some circuit boards, the whole rubber seal of described circuit board.
Further, two plugs damping means and rubber spring are pressed abd fixed in compression tube are also comprised.
Further, described plug is connected with ten core print seat cover and semi-rings.
Further, described damping means is selected from the one in cydariform snubber, rubber bar or vibration damping stage clip.
As mentioned above, the utility model not by means of only arranging damping means and rubber spring realizes compound antivibration in the axial direction to inserting tube core, and can realize radial antivibration by being arranged on the seal visiting die external.In addition, optical fibre gyro is also by circuit board rubber seal, and diameter dimension increases and arranges the means increase vibration resistance of trip bolt.Therefore, vibration proof structure of the present utility model is simple, and cost is also lower, not only increases service precision, and can avoid reliably because impacting the device damage caused comparatively greatly.
Accompanying drawing explanation
Accompanying drawing 1 is the structural representation of the utility model embodiment.
In figure: 1-ten core print seat cover, 2-semi-ring, 3-plug, 4-damping means, 5-gear, 6-optical fibre gyro, 7-add table, 8-O type rubber ring, 9-electronics storehouse, 10-compression tube, 11-rubber spring.
Detailed description of the invention
For making above-mentioned feature and advantage of the present utility model become apparent, special embodiment below, and coordinate institute's accompanying drawing to be described in detail below.
As shown in Figure 1 for the structure of boring gyrolevel inserting tube antivibration, comprising: ten core print seats covers 1, semi-ring 2, plug 3, damping means 4, gear 5, optical fibre gyro 6, add table 7, O type rubber ring 8, electronics storehouse 9, compression tube 10 and rubber spring 11.
Wherein ten core print seat covers 1 and semi-ring 2 fix ten core connectors to realize the electrical connection with another structure centralizer; plug 3 is fixed in compression tube 10 by inserting tube skeleton (comprising inserting tube core, damping means and rubber spring); also be realize the anatomical connectivity with another structure centralizer, compression tube 10 plays pressure protect effect to whole inserting tube skeleton simultaneously.
During with the work of brill gyrolevel, adopt optical fibre gyro 6 acquisition angle velocity information, the vibration resistance of optical fibre gyro 6 is poor, in this inserting tube, the diameter dimension of the optical fibre gyro 6 used in the past is brought up to Φ 58mm from traditional Φ 50mm by us, inner trip bolt strengthens, circuit board sealing, increases structural strength and the resistance to shock of optical fibre gyro 6 itself.Make optical fibre gyro 6 one end and inserting tube structure middle gear 5 fix, the other end is fixed with the dial framework fixedly adding table 7 simultaneously.Three components of sensitive carrier acceleration are responsible for by the accelerometer of three mutually orthogonal installations; The dial framework installing accelerometer arranges multidiameter, and the stress of axle head chamfering minimizing is simultaneously concentrated.Four circuit boards are installed in electronics storehouse 9, and the whole sealing of circuit board, increases its vibration resistance.Whole inserting tube core lower end and damping means 4 are fixed, and upper end is fixing with shock-absorbing spring 11, and last plug 3 compresses damping means 3 and rubber spring 11, is pressed in compression tube 10 by whole inserting tube core, make it must not play up and down.Damping means 4 and rubber spring 11 play the effect of axial vibration damping.Visit all O type rubber rings 8 with it of die external to fit tightly with compression tube 10, whole inserting tube core is played to the effect of radial vibration-reducing.
The bolster visiting die external can also use flower pattern rubber ring, or O type rubber ring is combined according to concrete operating mode with flower pattern rubber ring, to reach better effectiveness in vibration suppression.
Although the utility model describes as above with aforesaid embodiment, it can not in order to limit the utility model.Those of ordinary skill in the utility model art, not departing from spirit and scope of the present utility model, does a little change and modification, all in protection domain of the present utility model.Therefore protection domain of the present utility model is when being as the criterion with the claim person of defining.
