Abstract
The utility model relates to the oil and gas field exploration and exploitation field and specifically an oil and gas field rock core geologic body measuring apparatus comprising a fixed plate, a rotating plate, a rotating shaft and a spiral carved line, wherein the fixed plate is connected with the rotating plate through the rotating shaft, the rotating plate can rotate around the rotating shaft in a plane, and the spiral carved line is carved on the rotating plate. The rock core geologic body measuring apparatus is characterized in that the defect that a method of measuring geologic bodies through straight scales is large in error, poor in accuracy and difficult in reading can be overcome; the length of rock core geologic bodies can be accurately measured.
Description
Technical field
The utility model relates to oilfield prospecting developing field, especially a kind of measurement mechanism of oil gas field rock core geologic body.
Background technology
In oil-gas exploration and development process, often need geologic body fine description on rock core, comprising the linear measure longimetry of rock core geologic body, the geologic body that will observe on rock core comprises little gravel, ancient organisms, dissolution pore, kalzit mineral etc., these geologic bodies have the advantages that length is short, on rock core, be irregular spread, classic method often adopts common ruler while measurement, but generally can only be accurate to millimeter due to common ruler, the numerical value accuracy of reading is low, the scale spacing of ruler is intensive in addition, rock core is cylindric, causes and reads, estimates read data difficulty.
Utility model content
The utility model is intended to address the above problem, a kind of rock core geologic body measurement mechanism is provided, it overcome adopt that ruler measures that geologic body error is large, the drawback of out of true, reading difficulty, its technical scheme adopting is as follows:
A kind of rock core geologic body measurement mechanism, comprises fixed head, swivel plate, rotating shaft, spiral groove, and described fixed head is connected with swivel plate by rotating shaft, and described swivel plate can planar rotate around the shaft, and described spiral groove is portrayed on swivel plate.
On technique scheme basis, described fixed head bottom surface is circular arc, is cylindrical radial perpendicular to A-A profile line direction.
On technique scheme basis, the scale of described spiral groove is spiral fashion, different from common ruler scale close-packed arrays, the sparse arrangement of scale of spiral groove, and scale is spiral increase on swivel plate.
The utlity model has following advantage: reasonable in design, easy to use, can accurately measure the length of rock core geologic body, workable, easy to carry.
Brief description of the drawings
Fig. 1 is perspective view of the present utility model;
Fig. 2 is A-A sectional view in Fig. 1;
Fig. 3 is B-B sectional view in Fig. 1;
Fig. 4 is the making schematic diagram of spiral groove in Fig. 1;
In figure: 1. fixed head, 2. swivel plate, 3. rotating shaft, 4. spiral groove.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Shown in accompanying drawing, a kind of rock core geologic body measurement mechanism, comprise fixed head 1, swivel plate 2, rotating shaft 3, spiral groove 4, described fixed head 1 is connected with swivel plate 2 by rotating shaft 3, the 3 planar rotations around the shaft of described swivel plate 2, described spiral groove 4 is portrayed on swivel plate 2, and described fixed head 1, swivel plate 2 are clear glass steel.
Preferably, described fixed head 1 bottom surface is cylindrical radial perpendicular to A-A profile line direction, and its effect is that measurement mechanism is close on rock core to be measured, is convenient for measuring the length of rock core geologic body.
Preferably, the scale of described spiral groove 4 is spiral fashion spread, different from common ruler scale close-packed arrays, the sparse arrangement of scale of spiral groove 4, scale is spiral increase on swivel plate 2, its effect is that scale is evenly distributed in swivel plate 2, and between scale, spacing is sparse, is convenient to reading of data.
The preparation process of spiral groove 4 as shown in Figure 4, minimum radius of circle is 1mm, then draw the circle of a series of radiuses interval 1mm and arrange with the minimum concyclic heart of circle, be 0 °, 45 °, 90 °, 135 °, 180 °, 225 °, 270 °, 315 some mark successively by circle top parallactic angle, as shown in Figure 4, gauge point is connected with smooth curve, on the smooth curve connecting, can go out less scale by Further Division.
In use, by the circular arc coupling of B-B direction on rock core to be measured and fixed head 1, rotating shaft 3 is alignd with one end of geologic body to be measured, rotate swivel plate 2, until spiral groove 4 is tangent with the geologic body other end, read the scale numerical value at point of contact place, because the spacing between adjacent scale is large, scale is easy to identification, thereby makes the data that read have degree of precision.
With way of example, the utility model is illustrated above, but the utility model is not limited to above-mentioned specific embodiment, all any changes of doing based on the utility model or modification all belong to the claimed scope of the utility model.
