Abstract
The invention discloses a bit gauge capable of ensuring horizontal state during measurement, and aims at solving the problem that a bit gauge in the prior art is hard to ensure the horizontal state during measurement, and improving the measuring precision of the bit gauge. The bit gauge comprises a casing, an internal sheet, a handle, a scaled bar, an adjusting rod and a level meter, wherein the scaled bar and the adjusting rod are arranged at the upper surface of the casing, and the level meter is arranged in the upper surface of the bit gauge.
Description
Technical field
The present invention relates to bit gauge field, concretely relate to a kind of bit gauge guaranteeing that level is measured.
Background technology
Bit gauge, it is for measuring the common tool of the gauge size of the wear-out part such as drill bit, centralizer in oil and gas well drilling industry, it can measure the maximum gauge of the drill bit before and after well, centralizer, contrast draws drill bit and the centralizer abrasion condition in down-hole, judges whether that changing BHA provides data support for drilling engineer.Use in bit gauge measurement process, it is inserted in the gauge place being in upright or the drill bit to be measured of suspended state, centralizer, bit gauge is held level with both hands with hands, stir adjusting rod clockwise, making bit gauge internal sheet inwardly produce until being adjacent to place to be measured, now namely the size of the pointer indication of adjusting rod is measured external diameter.
Bit gauge needs user to maintain it in level in measurement process, otherwise measured outside dimension can have bigger error, affect engineer to instrument, stratum, borehole size judgement, even result in the engineering accident such as bit freezing, card sleeve pipe, therefore whether bit gauge measurement process is in level particularly significant.But, existing bit gauge only relies on user and estimates whether level when using, be very easy to cause measurement error.
Summary of the invention
It is an object of the invention to provide a kind of bit gauge guaranteeing that level is measured, the problem solving to use bit gauge to be difficult to ensure that its level when measuring in prior art, it is achieved improve the purpose of bit gauge certainty of measurement.
The present invention is achieved through the following technical solutions:
A kind of bit gauge guaranteeing that level is measured, including shell, internal sheet, handle, and is arranged at the scale strip of upper surface of outer cover, adjusting rod, also includes the level indicator being arranged at described bit gauge upper surface.The problem being difficult to ensure that its level when measuring for existing bit gauge, the present invention proposes a kind of bit gauge guaranteeing that level is measured, by arranging level indicator at bit gauge upper surface, level indicator is utilized to come intuitively, judge whether bit gauge is in level accurately, thus realizing improving the purpose of bit gauge certainty of measurement.In use procedure of the present invention, first described adjusting rod is rotated counterclockwise, described internal sheet is gone in shell, latus rectum in the middle of bit gauge is made to be in maximum rating, bit gauge is inserted in the gauge place being in upright or the drill bit to be measured of suspended state, centralizer again, observe described level indicator, adjust the angle of bit gauge simultaneously, level indicator is made to show to level and remain stationary as, stir adjusting rod clockwise simultaneously, making bit gauge internal sheet produce until being adjacent to place to be measured, now namely the size of the pointer indication of adjusting rod is measured external diameter.
Preferably, described level indicator is arranged near described scale strip.Described level indicator is arranged near scale strip, it is simple to user remains able to when reading scale use remaining light that level indicator is observed, it is ensured that the numerical value of reading is to obtain under bit gauge level, further ensures that the precision of measurement.
Preferably, described level indicator is arranged at described handle upper surface.Handle is the place that bit gauge width is maximum, and the level indicator on handle could be arranged to the level indicator that area is relatively big, precision is higher, in order to observe and operation.
Preferably, described level indicator is air-bubble level.Conveniently, user only needs to observe whether bubble is in the horizontal center point of transparent plate, and the position according to bubble is adjusted, and namely can ensure that bit gauge is in level, it is ensured that certainty of measurement for air-bubble level simple in construction, observation.
To sum up, the method have the advantages that
A kind of bit gauge guaranteeing that level is measured of the present invention, by arranging level indicator at bit gauge upper surface, utilizes level indicator to come intuitively, judge whether bit gauge is in level accurately, thus realizing improving the purpose of bit gauge certainty of measurement.
