Abstract

The utility model provides a light wt. shock-proof instrument for measuring inclination, which can work stably in vibration condition and ensures to acquire recording data after precision measurement to overcome the defects of the prior art. The utility model has the advantages that a controller 2 and a camera 3 are formed to an integral structure to reduce the volume and weight of the two mechanisms. The utility model solves the conflict among vibration, damping and measuring precision by using the structure of a single magnetic needle compass assembly 8 and a damping ring 6 and matching with damping fluid 5 with proper damping coefficient. The work of the compass assembly can be more sensitive and accurate by using a compass finial.

Description

A kind of light-duty antidetonation tiltmeter

The utility model relates to the gradient of measuring well in a kind of oil geology drilling engineering and the surveying instrument of direction and Tool Face Angle, be particularly suitable for self-floating deviational survey instrument quality little, in vibrations, finish accurate Testing requirement.

Self-floating well logging is to utilize the mud impulse force of drilling engineering that instrument and carrier thereof are delivered to the shaft bottom, and termination of pumping relies on later on the buoyancy of carrier and floats to well head, obtains measurement data.Make instrument rest on the drill bit place because apparatus measures work the time gets turn on pump, under the effect of hydraulic shock power the instrument vibrations very big, the work under bad environment of instrument, the precision of measurement are difficult to ensure that particularly super degree of depth well is particularly outstanding.

The purpose of this utility model is to provide a kind of light-duty antidetonation deviational survey instrument, makes its steady operation under above-mentioned working condition, and guarantees to obtain accurate survey record data, to overcome the defective that prior art exists.

Below in conjunction with accompanying drawing the utility model is described in detail. Such as accompanying drawing 1, below battery sleeve 1, arrange Controller 2 and camera 3 be integrated apparatus with shell; It is total that its underpart connects measuring cylinder Become 9. Measuring cylinder is total to be become 9 interior orders angle measurement hang spring ring always becomes 7 to having, single magnetic compass is total Become 8, reflective cover 10, compass are top 11, center sleeve 12, bellows 13; Its bottom T shape 14. The total one-tenth 9 of measuring cylinder is a closed structure, and its inner chamber is full of damping fluid 5, and submergence is equipped with angle measurement The total one-tenth 7 of hang spring ring. Such as accompanying drawing 2, single magnetic compass always becomes 8 by the compass face 20 with digital calibration Form with the needle 21 of middle with hole. Such as accompanying drawing 3, the total one-tenth 7 of hang spring ring connects resistance by angle measurement hang spring 4 The Buddhist nun encircle 6 and hang spring ring 16 consist of. Such as accompanying drawing 4, the top angle [alpha] of compass top 11 is the 18-28 degree. The kinematic viscosity of damping fluid 5 is the 10-300 centistoke.

Embodiment: when instrument arrives the shaft bottom down with the well logger toter, because the hole deviation effect in shaft bottom makes angle measurement hang spring 4, damping ring 6 and the hang spring ring 16 one deviation instrument axis of angle measurement mechanism, projection on single magnetic compass assembly 8 can reflect the size and Orientation at inclination angle, battery tube 1 is to controller 2 power supplies, and controller 2 is controlled the photo opportunity and the time of cameras 3.Because angle measurement mechanism is immersed in the bigger damping fluid of ratio of damping 5 neutralization because the effect of damping ring 6, be not subject to the influence vibrated, so in vibration environment, still can accurately clearly take the figure of reflection hole deviation data.Because use single magnetic compass assembly 8, its magnetic moment of torsion is bigger, so still can guarantee the degree of accuracy of its direction in the bigger damping fluid of ratio of damping.

The utility model has the advantages that: controller 2 and camera 3 are made integrative-structure, reduced the volume and the weight of this two mechanism.Adopt single magnetic compass assembly 8 and damping ring 6 structures, cooperate the damping fluid 5 of suitable ratio of damping, solved the contradiction of vibrations, damping and measuring accuracy well.The compass that adopts is top, can make the work of compass assembly sensitiveer accurately.
