Description

It is a kind of to change pipe nipple with brill MWD pulsers valve cylinder
Technical field
The utility model belongs to oil drilling measurement while-drilling instrument technical field, particularly relates to a kind of with brill MWD Pulser valve cylinder changes pipe nipple.
Background technology
Centerfire MWD are the passages that are transmitted using mud as signal with pulser is bored.Pulser is as underground signal Generating means, upper end connection orientation inserting tube, lower end connection valve cylinder and guide shoe.During site operation, the positioning equipped with circulating sleeve is short Section is connected on drilling tool, is then put into the MWD instrument strings assembled in drilling tool, the guide shoe of pulser just falls in circulating sleeve It is interior.When starting drilling-fluid circulation system, orientation inserting tube is controlled the servo valve events of pulser with the coded system set, causes valve Cylinder, the mud pressure changes in balance in guide shoe, the valve rod on guide shoe are moved back and forth, when valve rod moves downward, blocked in circulating sleeve Restrictor ring, reduce drill string area of passage, pressure rises in drill string, and when moving upwards, pressure restores balance in drill string.So as to A series of mud-pressure pulses are generated in drill string.Mud pressure sensor on standpipe detects this pulse sequence Row, sampling, the decoding to mud-pulse are completed through exclusive data processing instrument, obtains the metrical information of downhole instrument.Under pulser Hold valve cylinder, guide shoe and the orientation spool of connection(Including circulating sleeve and annex etc.)Inside and outside wall Deng part is exposed in mud, Slurry erosion constantly is subjected to, occurs that tube wall is thinning frequently, pierces situations such as leaking.The parts such as valve rod are in swiftly flowing mud Ceaselessly move back and forth, mechanical wear is inevitable.The above component wear to a certain extent, or there was a mechanical failure must Change, and all the time, these parts are expensive all from external import or special processing, occupied in construction cost larger Share.
The content of the invention
The utility model makes up the deficiencies in the prior art aiming above mentioned problem, there is provided a kind of with brill MWD pulser valves Cylinder conversion pipe nipple;The utility model is used for sea blue YST-48R MWD with brill instrument to be a kind of(Including clone)Valve cylinder Centerfire MWD are connected to the conversion pipe nipple bored on pulser.
To achieve the above object, the utility model adopts the following technical scheme that.
The utility model one kind changes pipe nipple with MWD pulsers valve cylinder is bored, it is characterised in that:Including changing nipple body, Described conversion nipple body both ends are respectively arranged with conversion pipe nipple pin end, conversion pipe nipple box end, and the conversion pipe nipple is public End of thread connects Centerfire MWD and connects sea blue YST-48R MWD with brill instrument with pulser, the conversion pipe nipple box end is bored The valve cylinder of device, the sealing ring changed on the sealing surface and valve cylinder of pipe nipple box end is connected, described to change the interior of nipple body Footpath is identical with valve cylinder internal diameter;Two seals circle, difference are provided with the conversion nipple body of conversion pipe nipple pin end is provided with For the first sealing ring and the second sealing ring, first sealing ring and the second sealing ring are separately positioned on conversion pipe nipple pin end Both sides, first sealing ring, the second sealing ring and the sealing surface on pulser are connected.
As a kind of preferred scheme of the present utility model, the outer tube wall of the conversion nipple body is without raised and groove;This Sample can reduce the influence that mud washes away, and increase the service life.
As another preferred scheme of the present utility model, the overall length for changing nipple body is 11CM.
Specifically, the utility model is changed into pipe nipple respectively with Centerfire MWD with brill pulser, sea blue YST-48R After MWD is linked and packed with the valve cylinder for boring instrument, length only makes former instrument increase 6.5CM.
The beneficial effects of the utility model compared with prior art.
1st, by using the utility model, by Centerfire MWD with bore the pulser lower end connection country widely use, Cheap sea blue YST-48R MWD are with brill instrument(Including clone)Valve cylinder, guide shoe, circulating sleeve, orientation spool etc. Part;Instead of former part, to improve the versatility of part, production cost is saved, shortens delivery cycle, increases economic efficiency.
2nd, the utility model is simple in construction, easy for installation, does not change former apparatus structure;By the utility model conversion pipe nipple point After not being linked and packed with Centerfire MWD with brill pulser, sea blue YST-48R MWD with the valve cylinder for boring instrument, length only makes Former instrument increases 6.5CM, and apparatus measures point is influenceed can be neglected, less influences former instrument performance;Improve the logical of part With property, use cost is reduced, improves economic benefit.
Brief description of the drawings
In order that technical problem, technical scheme and beneficial effect that the utility model solves are more clearly understood, below With reference to the drawings and the specific embodiments, the utility model is further elaborated.It should be appreciated that tool described herein Body embodiment only to explain the utility model, is not used to limit the utility model.
Fig. 1 is that the utility model is a kind of with the structural representation for boring MWD pulsers valve cylinder conversion pipe nipple.
Marked in Fig. 1:1 is conversion pipe nipple box end;2 be conversion pipe nipple pin end;3 be the first sealing ring;4 be second close Seal;5 be conversion nipple body.
Embodiment
With reference to shown in accompanying drawing 1, the utility model one kind changes pipe nipple with MWD pulsers valve cylinder is bored, it is characterised in that:Including Nipple body 5 is changed, the described both ends of conversion nipple body 5 are respectively arranged with conversion pipe nipple pin end 2, conversion pipe nipple box end 1, the conversion pipe nipple pin end 2 connects Centerfire MWD and connects sea blue with pulser, the conversion pipe nipple box end 1 is bored YST-48R MWD are with the valve cylinder for boring instrument, and the sealing ring changed on the sealing surface and valve cylinder of pipe nipple box end 1 is connected, institute The internal diameter for stating conversion nipple body 5 is identical with valve cylinder internal diameter;On the conversion nipple body 5 of conversion pipe nipple pin end 2 is provided with It is provided with two seals circle, is respectively the first sealing ring 3 and the second sealing ring 4, the sealing ring 4 of the first sealing ring 3 and second It is separately positioned on the both sides of conversion pipe nipple pin end 2.
