Each gage beam for hole diameter in the utility model has two separate groups of compressed springs, thereby each beam has enough pushing force on the sidewall of the well during the logging. And each beam can move separately to adapt to the logging of the diameters of the holes of the wells with different dips.
Description
Technical field
The utility model belongs to the oil exploration logger, is specifically related to a kind of herringbone inclined shaft caliper logging tool.
Background technology
Horizontal well, inclined shaft are a kind of drilling modes very general in the oil drilling.Get the well of different gradients along with the difference of region.Present domestic logger belongs to the straight well measuring apparatus basically, does not also have horizontal well, inclined shaft caliper logging instrument preferably.
Summary of the invention
The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art, provides a kind of simple in structure, and is stable, reliable, high-precision herringbone caliper logging tool.
For achieving the above object, the technical solution adopted in the utility model is: the processing of circuit assembly that comprises main casing and be arranged on main casing one side, the processing of circuit assembly is connected with displacement transducer, every group of displacement transducer is connected with contact lever, contact lever is provided with the displacement transducer stage clip, the other end of contact lever is connected with the caliper logging upper arm by shaven head, the outside of displacement transducer also is provided with the shaven head stage clip, it also comprises the caliper logging underarm sliding sleeve hinged with main casing, in caliper logging underarm sliding sleeve, be provided with caliper logging underarm stage clip and the caliper logging underarm hinged with the caliper logging upper arm, also be provided with at the opposite side of main casing and actuate driven unit, actuating driven unit is connected with stage clip box in being arranged on main casing by outer pushing plate, in the stage clip box, be provided with caliper logging upper arm stage clip and slide bar, one end of slide bar and connecting rod is hinged, the other end of connecting rod and caliper logging upper arm are hinged, and also offer on main casing and the corresponding chute of caliper logging arm; The upper and lower arm of caliper logging has four groups to be symmetrically arranged vertically.
Because caliper logging arm component of the present utility model has separately independently two groups of stage clips, thereby make in caliper logging, not only each arm produces enough backup power to the borehole wall, and each arm can self-movement, thereby in use can be suitable for the measurement of the oil well hole diameter of various gradients.
Description of drawings
Accompanying drawing is an overall structure schematic diagram of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing structural principle of the present utility model and operating principle are described in further detail.
Referring to accompanying drawing, the processing of circuit assembly 1 that the utility model comprises main casing 19 and is arranged on main casing 19 1 sides, processing of circuit assembly 1 is connected with four groups of displacement transducers 2 that are symmetricly set in the main casing 19, every group of displacement transducer 2 is connected with contact lever 4, contact lever 4 is provided with displacement transducer stage clip 17, the other end of contact lever 4 is connected with caliper logging upper arm 8 by shaven head 5, the outside of displacement transducer 2 also is provided with shaven head stage clip 3, on main casing 19, also be hinged with caliper logging underarm sliding sleeve 14, in caliper logging underarm sliding sleeve 14, be provided with caliper logging underarm stage clip 13 and the caliper logging underarm 12 hinged with caliper logging upper arm 8, opposite side at main casing 19 centers also is provided with and actuates driven unit 16, actuating driven unit 16 is connected with stage clip box 9 in being arranged on main casing 19 by outer pushing plate 15, in stage clip box 9, be provided with caliper logging upper arm stage clip 10 and slide bar 7, slide bar 7 is hinged with an end of connecting rod 6, the other end of connecting rod 6 and caliper logging upper arm 8 are hinged, and also offer on main casing 19 and the corresponding chute 18 of caliper logging arm.
The course of work of the present utility model is as follows: at first move to left by actuating driven unit 16 drive outer pushing plates 15, promote hole diameter stage clip box 9, caliper logging upper arm stage clip 10, slide bar 7 and connecting rod 6 move to left synchronously, connecting rod 6 is swing simultaneously in the process that moves to left, promote caliper logging upper arm 8 and be flared to maximum, when opening, caliper logging upper arm 8 drives caliper logging underarm 12, caliper logging underarm stage clip 13 and caliper logging underarm sliding sleeve 14 are swung together and are opened, and skid off from caliper logging underarm sliding sleeve 14 under the spring pressure of caliper logging underarm stage clip 13 when caliper logging underarm 12 opens.When underarm was flared to maximum in the caliper logging, be maximum hole diameter state this moment.If the hole diameter diameter reduces, four groups of caliper logging arms draw in, in the gathering process of caliper logging upper arm 8, connecting rod 6 is drawn in, promotion slide bar 7 moves to left and compresses caliper logging upper arm stage clip 10, and caliper logging underarm 12 further slides in the caliper logging underarm sliding sleeve 14 on the other hand, promotes 13 compressions of caliper logging underarm stage clip, when reaching minimum hole diameter, two groups of stage clips are operated in maximum working load.In caliper logging upper arm 8 and shaven head 5 swing process, the stage clip 17 of displacement transducer 2 contacts the pull bar of displacement transducer all the time with contact lever 4.Shaven head stage clip 3 contacts contact lever 4 all the time with shaven head 5, thereby converts the amount of moving radially of caliper logging arm end to displacement transducer variation of output signals amount, the diameter in cross section everywhere in the treated acquisition well.
