Abstract
The utility model relates to a pulse generator of a novel mechanical plumb shaft clinometer. According to the technical scheme, the pulse generator of the novel mechanical plumb shaft clinometer comprises a pulse barrel, a pulse head, a pulse rod, throttling rings and a connector. A plurality of sets of throttling rings used for generating pressure fluctuation are arranged on the inner wall of the pulse barrel, the pulse head and the pulse rod are fixedly connected together through the connector, the end of the pulse head is of a cone structure, the outer surface of the pulse head is coated with a thermal spraying coating, and the pulse head and the pulse rod are mounted in an inner cavity of the pulse barrel. The pulse generator of the novel mechanical plumb shaft clinometer has the advantages that the pulse barrel, the pulse rod and the pulse head are optimally designed, compared with a mechanical plumb shaft clinometer in the existing market, the service life is longer, signals are clear and definite, and the service life of the instrument is prolonged.
Description
Technical field
The utility model relates to a kind of oil field straight well inclinometer, particularly a kind of impulse generator of mechanical straight well inclinometer.
Background technology
The current electronic single-point inclination measuring that mainly contains for straight well deviational survey, EMI, mechanical wireless is with drilling straight-hole inclinometer, electronic single point and EMI can not be with boring deviational survey, and be not suitable for deep-well and hp-ht well, mechanical wireless can meet the deviational survey of deep-well and HTHP straight well with drilling straight-hole inclinometer, but pulse signal generator part is easily subject to slurry erosion, affects instrument application life.
Summary of the invention
The purpose of this utility model is exactly in view of the foregoing defects the prior art has, provides a kind of impulse generator of mechanical straight well inclinometer, the application life of having improved impulse generator.
Its technical scheme is: comprise pulsation cylinder, pulsation head, pulsation bar, restrictor ring, joint, described pulsation cylinder inwall is provided with the many groups of restrictor rings for generation of pressure oscillation, pulsation head is connected and fixed by joint with pulsation bar, the end of described pulsation head is vertebral body structure, a pulsation external surface scribbles thermally sprayed coating, and described pulsation head and pulsation bar are arranged on the inner chamber of pulsation cylinder.
Above-mentioned pulsation head comprises end, neck, afterbody, and described end is vertebral body structure, and neck is columnar structured, and afterbody is little vertebral body structure, and end connects afterbody by middle neck.
The beneficial effects of the utility model are: through the pulsation cylinder of optimal design, pulsation bar and external surface scribble the pulsation head of thermally sprayed coating, and the interval of shortening each restrictor ring, thereby longer service time than the mechanical type straight well inclinometer on existing market, signal is clear and definite, has improved the application life of instrument.
Brief description of the drawings
Accompanying drawing 1 is structural representation of the present utility model;
Accompanying drawing 2 is structure charts of pulsation head of the present utility model;
In upper figure: pulsation cylinder 1, pulsation 2, pulsation bar 3, restrictor ring 4, joint 5; End 2.1, neck 2.2, afterbody 2.3.
Detailed description of the invention
By reference to the accompanying drawings 1, the utility model will be further described:
The utility model comprises pulsation cylinder 1, pulsation 2, pulsation bar 3, restrictor ring 4, joint 5, described pulsation cylinder 1 inwall is provided with the many groups of restrictor rings 4 for generation of pressure oscillation, pulsation 2 is connected and fixed by joint 5 with pulsation bar 3, the end of described pulsation 2 is vertebral body structure, pulsation 2 external surface scribble thermally sprayed coating, and described pulsation 2 and pulsation bar 3 are arranged on the inner chamber of pulsation cylinder.
With reference to accompanying drawing 2, pulsation 2 comprises end 2.1, neck 2.2, afterbody 2.3, and described end 2.1 is vertebral body structure, and neck 2.2 is columnar structured, and afterbody 2.3 is little vertebral body structure, and end 2.1 connects afterbody 2.3 by middle neck 2.2.
The utility model is in use: pulsation 2 is under the effect of high speed mud, promoting pulsation bar 3 moves downward, moving downward in process, often just produce a pressure oscillation through a restrictor ring 4, the intensity that produces pressure pulse is closely associated with the structure design of frequency and pulsation cylinder 1, intensity is larger, frequency is lower washes away more serious to pulsation cylinder, affect application life, a pulsation of the present utility model external surface carries out hot spraying, and the interval of shortening each restrictor ring, just improve ripple frequency, can effectively increase the application life of impulse generator.
