Abstract
The utility model relates to a multifunctional caliper for a well site, which measures the diameter of a three-cone drill bit, various drilling tools, etc., in a well site for petroleum well drilling. The utility model is mainly composed of a main ruler, a fixed ruler, a vernier, a left and a right auxiliary rulers, an upper and a lower positioning blocks and a screw. Positioning slots of the upper and the lower positioning blocks are arranged on the fixed ruler, the vernier and the main ruler; the left and the right auxiliary rulers which can move up and down are arranged between the upper positioning block and the lower positioning block; the included angle of the measuring edge of each auxiliary ruler and a ruler body of the main ruler is 60 DEG. The caliper which enlarges the range of use can measure the inner and the outer diameters of the three-cone drill bit, a centralizer, a double-edge piece, a four-edge piece, other circular pieces, etc., and can also measure the inner diameter of various pipe tools and sleeve pipes.
Description
The utility model relates to a kind of petroleum drilling well site to multiple drilling tools such as the tricone bit measurer through measuring directly.
At present domestic each oil field is measured tricone bit, triangular centralizer or other circular drilling tool diameters and is all adopted the special-purpose well site of bikini slide calliper rule in drilling well site, its structure as shown in Figure 1, by fixedly slide calliper rule, slide calipers and blade constitute.But this bikini structure slide calliper rule weak point, the one, tricone bit, triangular centralizer diameter can only be measured, and the diameter of two ribs, four rib centralizers can't be measured; The 2nd, the measurement size scope is little, and as the slide calliper rule of accompanying drawing 1, the long 700mm of main scale, maximum measurement size are 340mm, so can not satisfy the requirement of large-scale metrology.
The purpose of this utility model is to overcome the shortcoming that existing bikini well site slide calliper rule application surface is narrow, the measurement size scope is little and designs a kind of multi-functional well site slide calliper rule, enlarge the usable range of slide calliper rule, can be to measurements digonous, four rib centralizers, and to measurement of big pipe, casing inner diameter etc.
The purpose of this utility model is achieved in that multi-functional well site slide calliper rule are mainly by main scale, scale, vernier, the secondary chi in a left side, right secondary chi, following locating piece, on the last locating piece, the next chi and clamp-screw constitute, this multi-functional well site slide calliper rule are to have increased a left side on the basis of former bikini well site slide calliper rule, the structure of right secondary chi two retaining location, main scale one end and scale join, also be provided with vernier on the main scale, at scale, vernier and main scale blade are provided with, the locating slot of following locating piece, between last locating piece and following locating piece, be provided with a left side moving up and down, right secondary chi, and by screw retention, a left side, the limit measured by right secondary chi and main scale blade angle is 60 degree; Also be provided with the parallel scale mark of two rows on the main scale blade.
The multi-functional well site of the utility model slide calliper rule compact conformation, the design ingenious, only big slightly than the well site slide calliper rule that use at present, but functions of use increases, the measurement size scope increases, not only can (140～480mm) measure to tricone bit and centralizer, also can carry out inner diameter measurement (60～650mm) and outside diameter measuring (0～600mm) to two ribs, four ribs or other circular pieces, the measurement size scope sum that is equivalent to combination function and two kinds of bikini well site slide calliper rule of three kinds of slide calliper rule has satisfied the various requirement of on-the-spot use.
Description of drawings
Fig. 1 is existing bikini well site slide calliper rule;
Fig. 2 is a multi-functional well site slide calliper rule structural representation;
Fig. 3 is for measuring external diameter user mode figure;
Fig. 4 is long-armed vernier caliper structural representation.
Among the figure: locating piece, the secondary chi screw of 2-, 3-scale, the secondary chi in a 4-left side, the last locating piece screw of 5-, the last locating piece of 6-, the right secondary chi of 7-, 8-vernier, 9-main scale, the upper chi of 10-, the next chi of 11-under the 1-.
Below in conjunction with accompanying drawing the utility model is further described: an end of main scale 9 is connected with scale 3, main scale is provided with vernier 8, on scale, vernier and main scale blade, be provided with the locating slot of upper and lower locating piece, be provided with left and right secondary chi moving up and down between last locating piece 6 and the following locating piece 1, and by screw retention, the limit measured by left and right secondary chi and main scale blade angle is 60 degree.When being the benchmark location by following locating piece, can measure 340mm following tricone bit and drilling tool size, when moving up by last locating piece location and tightening up, can measure tricone bit and the drilling tool size of 340～480mm.Constituted a long-armed vernier caliper when taking off remaining main scale, scale and the vernier of left and right secondary chi (dismantle earlier and go up locating piece 6), can be used to measure external diameter and other instrument external diameter of the drilling tool of two ribs, four rib even number seamed edges, can also measure the internal diameter of various pipes and sleeve pipe with scale and vernier external pelivimetry limit, the rule of internal diameter and external diameter is arranged respectively on back of the body chi.Increased the slide calliper rule function like this, because two retainings are located, and are equivalent to two bikini well site slide calliper rule of different measuring size section, the parallel scale mark of two rows is arranged on the main scale blade, upper chi 10 among the figure, the next chi 11 are respectively the rule of secondary chi two retaining location survey readings.
The left and right secondary chi of the utility model can slide on scale and vernier blade respectively, when measurement size is the tricone bit of 140～350mm or centralizer, secondary chi 4,7 is held out against down locating piece 1, tighten screw 2, can measure, read the next chi reading of main scale.When measurement size is the large-scale tricone bit of 340～480mm, secondary chi 4,7 is moved on to locating piece 6 places, and hold out against, tighten screw 2, read main scale 9 positive upper chi number of divisions when measuring.
Claims (2)
1, a kind of multi-functional well site slide calliper rule, constitute by main scale, scale, vernier, left secondary chi, right secondary chi, time locating piece, last locating piece, upper chi, the next chi and clamp-screw, it is characterized in that main scale one end and scale join, also be provided with vernier on the main scale, on scale, vernier and main scale blade, be provided with the locating slot of upper and lower locating piece, between last locating piece and following locating piece, be provided with left and right secondary chi moving up and down, and by screw retention, the limit measured by left and right secondary chi and main scale blade angle is 60 degree; Also be provided with the parallel scale mark of two rows on the main scale blade.
