Description
Technical field
the utility model relates to horizontal well erection device technical field, is a kind of horizontal wellbore logging erection device.
Background technology
the well logging centralizer that has at home a lot of routines, but only there is erection device to be seldom applied to the righting of horizontal wellbore logging instrument, the erection device that is applied at present horizontal wellbore logging instrument generally adopts spring leaf braced structures, but this erection device can not need to be changed centralizing support mechanism according to the internal diameter of different wells, can not adjust the side direction uprighting force of supporting mechanism.
Summary of the invention
the utility model provides a kind of horizontal wellbore logging erection device, overcome the deficiency of above-mentioned prior art, it can effectively solve the problem that erection device that existing erection device exists in actual use can not need to be changed centralizing support mechanism and can not adjust the side direction uprighting force of supporting mechanism according to the internal diameter of different wells.
the technical solution of the utility model realizes by following measures: a kind of horizontal wellbore logging erection device, comprise body, upper limit cover, lower limit cover and horizontal wellbore logging instrument, the through hole that has up/down perforation on body, upper limit cover, body and lower limit cover are fixedly mounted on the outside of horizontal wellbore logging instrument from top to bottom successively, are installed with the support arm that is no less than three in the outside of body.
the further optimization and/or improvements to above-mentioned utility model technical scheme below:
above-mentioned body is sleeved on the outside of horizontal wellbore logging instrument, in upper limit cover and lower limit, put and be distributed with the radially screw thread locating hole that is no less than two, upper limit cover and lower limit are overlapped respectively the outside that is fixed on horizontal wellbore logging instrument by radially screw thread locating hole and dog screw.
the inner side of above-mentioned body can have to be run through and spiral groove from top to bottom.
the number of above-mentioned groove can be three.
the outside of above-mentioned body can evenly be installed with six support arms; Or/and through hole is rounded.
all can there be chamfering in left end outside and the right-hand member outside of above-mentioned support arm; Or/and the shape of upper limit cover and lower limit cover is annular.
the utility model reasonable and compact in structure, easy to use, its in the process of righting logger, not only can according to well hole diameter need to change support arm, and can be according to the uprighting force that need to adjust support arm supporting.

coding in accompanying drawing is respectively: 1 for body, and 2 is upper limit cover, and 3 is lower limit cover, and 4 is support arm, and 5 is screw thread locating hole radially, and 6 is groove, and 7 is horizontal wellbore logging instrument.
The specific embodiment
the utility model is not subject to the restriction of following embodiment, can determine concrete embodiment according to the technical solution of the utility model and actual conditions.
in the utility model, for convenience of description, the description of the relative position relation of each parts is to be all described according to the Butut mode of Figure of description 1, as: the position relationship of forward and backward, upper and lower, left and right etc. is to determine according to the Butut direction of Figure of description 1.
below in conjunction with embodiment and accompanying drawing, the utility model is further described:
as shown in accompanying drawing 1 to 7, this horizontal wellbore logging erection device comprises body 1, upper limit cover 2, lower limit cover 3 and horizontal wellbore logging instrument 7, the through hole that has up/down perforation on body 1, upper limit cover 2, body 1 and lower limit cover 3 are fixedly mounted on the outside of horizontal wellbore logging instrument 7 from top to bottom successively, are installed with the support arm 4 that is no less than three in the outside of body 1.The setting of upper limit cover 2 and lower limit cover 3 can be fixed on body 1 on horizontal wellbore logging instrument 7; The setting of support arm 4 can be supported in horizontal well by horizontal wellbore logging instrument 7 securely, in addition, when using in need to the well at different hole diameters, by changing support arm 4, can be applied to the different well of hole diameter, moreover, can, according to the needs that support, adjust the uprighting force of support arm 4.
can according to actual needs, above-mentioned horizontal wellbore logging erection device be made further optimization and/or improvements:
as shown in accompanying drawing 1 to 7, body 1 is sleeved on the outside of horizontal wellbore logging instrument 7, on upper limit cover 2 and lower limit cover 3, be distributed with the radially screw thread locating hole 5 that is no less than two, upper limit cover 2 and lower limit cover 3 are fixed on respectively the outside of horizontal wellbore logging instrument 7 by radially screw thread locating hole 5 and dog screw.
as shown in Figure 4, in the inner side of body 1, have and run through from top to bottom and spiral groove 6.The setting of groove 6 can be played the effect of cleaning mud.
as shown in Figure 4, the number of groove 6 is three.
as shown in accompanying drawing 1 to 5, in the outside of body 1, be evenly installed with six support arms 4; Or/and through hole is rounded.The setting of six support arms 4 has the more firm effect of support, effectively prevents that supported horizontal wellbore logging instrument 7 from departing from the axis direction of horizontal well.
as shown in accompanying drawing 1 to 7, in outside, upper end and the outside, lower end of support arm 4, all there is chamfering; Or/and the shape of upper limit cover 2 and lower limit cover 3 is annular.
