Abstract
The utility model relates to a caliper having a double-sleeve measuring arm. An outer barrel comprises an upper and lower outer barrels (1, 9) and a lower joint (16). The two barrels (1, 9) and the connection of the lower barrel (9) and the lower joint (16) are assembled with an upper and lower sleeve measuring groups (8, 15). Fixed convex-shaped plungers (2, 10), plungers (6, 12) and concave-shaped plungers (19, 18) are arranged in the upper and lower outer barrels (1, 9). The utility model is also provided with a central push rod (5) by the plungers, and moreover, the middle part and the lower end of the push rod are provided with trays (7, 17) which can mutually act on short arms on measuring arms. Differential transformer type displacement sensors (3, 11) and drive rods (4, 13) are upwards distributed on the periphery of the upper and lower outer barrels (1, 9) by the plungers in the upper and lower outer barrels (1, 9), wherein one end of the drive rods (4, 13) can respectively act on upper contact heads of the displacement sensors (3, 11), and the other end of the drive rods (4, 13) can respectively act on the short arms of the measuring arms (8, 15). The caliper can measure a sleeve damage well of which the latus rectum is larger than 50 mm and can detect the degree of the sleeve damage by an oil pipe.
Description
Technical field
The utility model belongs to the measurement caliper, particularly relates to the caliper with two cover gage beams.
Background technology
At present, the caliper that is applied to engineering log is a lot, and calipers such as XYC, 4 arms, 8 arms, 12 arms, 16 arms, 36 arms, 40 arms are arranged, and the more caliper external diameter of these caliper gage beams is all bigger; The caliper that external diameter is less, its gage beam are generally less again, and the information content of gained is very limited.Each oil field is used slim-hole gradually instead and is recovered the oil in order to save the oil development cost; Many oil wells are longer owing to the development time simultaneously, and the situation of casing corrosion and distortion is comparatively serious, this type of situation, and the instrument that external diameter is bigger can't be gone into the well and be measured.And the user is more and more higher to the requirement of engineering log, requires the well logging achievement to have more intuitive and comprehensive, therefore, needs the caliper that external diameter is little, gage beam is many.The size of instrument external diameter directly defines the quantity of gage beam.
The utility model content
Technical problem to be solved in the utility model is at the problem that exists in the background technology, and the caliper of the two cover gage beams of having of a kind of suitable small-well-diameter and many gage beams is provided.
The invention for solving the technical problem can reach by following technical solution: urceolus is upper and lower urceolus, lower contact, reaches urceolus and lower contact junction to assemble upper and lower cover gage beam group at two; The convex plunger that installs and fixes in upper and lower urceolus, plunger, spill plunger have center push rod by above-mentioned plunger, have on push rod middle part and the lower end with gage beam on the pallet that acts on mutually of galianconism; Respectively the week by its inner plunger upwards is furnished with differential transformer displace, drive link in upper and lower urceolus, and wherein drive link one end acts on mutually with the displacement transducer upper contact head respectively, and the other end acts on mutually with the galianconism of gage beam respectively.
In such scheme, upper and lower cover gage beam can respectively be 10, and drive link, the displacement transducer of similar number.By this caliper of above forecast scheme configuration, by the design of upper and lower two cover gage beam, external diameter own is little; But total gage beam number is many, can reach purpose of design.
The utility model is compared with background technology has following beneficial effect: this caliper is created and has been utilized dexterously axially and radial space, has realized 20 caliper logging arms of instrument distribution of external diameter 50.Existing other caliper, external diameter is less than 50 instrument, and gage beam is very few, and maximum is 4 arms, and the hole diameter information of q.s can not be provided; Gage beam is more than 8 arms, and the instrument external diameter is out of shape well big, that latus rectum is little and can't measures all greater than 70, can not cross oil pipe and measure.This caliper has overcome the shortcoming of original instrument, can measure the casing damaged well of latus rectum greater than 50mm, and can cross oil pipe and detect the cover damage.
Description of drawings
Accompanying drawing 1,2nd, this caliper merogenesis figure.
The specific embodiment
Below in conjunction with the drawings and specific embodiments will the utility model is described in further detail:
By Fig. 1, shown in 2, urceolus is upper and lower urceolus (1,9), lower contact 16, and urceolus 9 is assembled upper and lower cover gage beam group (8,15) with lower contact 16 junctions under two (1,9) reach; The convex plunger (2,10), plunger (6,12), the spill plunger (19,18) that install and fix in upper and lower urceolus (1,9) lining have center push rod 5 by above-mentioned plunger, have on push rod middle part and the lower end with gage beam on the pallet (7,17) that acts on mutually of galianconism; At upper and lower urceolus (1,9) lining respectively upwards is furnished with differential transformer displace (3 by the week of its inner plunger, 11), drive link (4,13), wherein drive link (4, a 13) end acts on mutually with displacement transducer (3,11) upper contact head respectively, the other end acts on mutually with the galianconism 14 of gage beam (8,15) respectively.
In such scheme, upper and lower cover gage beam (8,15) can respectively be 10, and drive link (4,13), the displacement transducer (3,11) of similar number, can satisfy measurement requirement.Above scheme constitutes upper and lower pair of cover caliper according to the principle design of single cover caliper commonly used, center push rod 5 is linked as a caliper to upper and lower cover gage beam, transmission mechanism is converted to the axially-movable of center push rod with the circumferential movement of motor, and center push rod drives two-layer measuring mechanism simultaneously by upper and lower two-layer pallet and axially moves.Open gage beam during measurement, every gage beam by drive link under the effect of spring force, tightly be close to the borehole wall and move up, the cam structure by gage beam is transformed into the variation of the axial location of sensor with the well radius variations of hole diameter, thereby records different sleeve pipe inside radius.
