Abstract
The utility model relates to an anti-seismic logging magnetic angle meter, which is additionally provided with a motion damping device for the logging magnetic angle meter on a moving element and is mainly composed of a camera connecting screw, a lens, a casing, damping fluid, a dip angle pendulum bob, a transparent pendulum damping tube, a dip angle dial, an azimuth compass, a compass damping blade, a centre shaft, a corrugated pipe assembly and a T-shaped head. The utility model is characterized in that the utility model can cause the moving element (the dip angle pendulum bob, the azimuth circle) of the logging magnetic angle meter to be relatively stable and obtain photographs with clear and accurate dip angles, azimuth and tool faces under the vibration environment of the drilling fluid.
Description
The utility model relates to the magnetic angle-measuring equipment of measuring wellhole inclination angle, orientation, Tool Face Angle in a kind of drilling engineering, belongs to the engineering measuring technology field.
The deviational survey instrument that uses in the petroleum drilling usually has to be in when work among the vibration environment, and particularly under the effect of hydraulic shock power, the instrument vibrations are very big, and accurately difficulty is caused in measurement hole deviation, orientation, Tool Face Angle etc. thereby give.
The purpose of this utility model is to provide a kind of antidetonation type well logging magnetic angle-measuring equipment of realizing accurately well logging among the vibration environment of circulation of drilling fluid.
The technical scheme that the utility model adopted is as follows.
Antidetonation type well logging magnetic angle-measuring equipment, form by camera lens, shell, damper tube, pendulum, index dial, compass, blade, axle and T connector, it is characterized in that: after connecting camera lens (2), damping fluid (4), pendulum damper tube (5), inclination angle pendulum (6), index dial (7), azimuth compass (8), compass damping vane (9), tail spindle (10), corrugated tube assembly (11) in the shell of tubular (3) successively, its end T connector (12) that spins, and set screw (13) is set.
Transparent pendulum damper tube (5) is fixed in the inclination angle pendulum mechanism (6), moves with inclination angle pendulum mechanism (6).Compass damping vane (9) is fixed under the azimuth compass (8), rotates with azimuth compass (8).
Be characterized in: can among the vibration environment of circulation of drilling fluid, make the moving component (inclination angle pendulum, azimuth compass) in the well logging magnetic angle-measuring equipment relatively stable, obtain clear and accurate inclination angle, orientation, tool-face photo by taking pictures.
Further specify the utility model below in conjunction with drawings and Examples.
Accompanying drawing is the cut-open view of the utility model antidetonation type well logging magnetic angle-measuring equipment.
