Description
The present invention relates to be applied in the geology core Physical Property Analysis a kind of method that the arbitrary-shaped core volume is measured, and the instrument of realizing this measuring method.
The core volume measuring method of present domestic use is, core is put in the container that fills mercury, read the variable quantity of its capacity before and after core drops into,, can try to achieve the volume (this surveying instrument is produced by instrucment and meter plant of University of Petroleum) of tested core again with the proportion of this variable quantity divided by mercury.
The comparatively advanced core volume measuring method that adopts at present in the world is, paste the polymeric membrane of the thin solubility of one deck on the surface of core, core is placed in a kind of container, uses the volume (academic report of the doctor Wei Jing of Norway engineering college: the status and prospects of core analysis technology) of measuring core with the similar method of above-mentioned domestic method.
Obviously there is following shortcoming in the method for domestic use:
1, the staff will contact mercury inevitably, and it is healthy that mercury volatilization back sucks the interior meeting influence of human body.
2, mercury will permeate in the core hole, make the core volume that records less than normal, simultaneously, owing to infiltrate mercury in the hole, can influence subsequent experimental.
Though external method has solved the problem of sepage in the core hole basically, but the process conditions harshness that pad pasting requires, as need paste quite smooth, also to vacuumize after posting, this has increased the complicacy of measuring process undoubtedly, and the volume of film is also influential to the accuracy of measuring.
Above-mentioned international and domestic measuring method also all exists a common issue with, promptly can not directly read the volume of tested core, because of its volume also will convert with fluid density.
The present invention is just in that above-mentioned some deficiencies propose in order to overcome.
First purpose of the present invention provides a kind of measuring method of new arbitrary-shaped core volume.
Second purpose of the present invention provides a kind of surveying instrument of the present invention's of realization first purpose.
The 3rd purpose of the present invention provides a kind of a kind of method that the core volume prints measurement report of directly reading.
According to first purpose of the present invention, this measuring method is certain with granularity, apparent density is certain, flowability preferably globular metallic powder as measuring media, use a measuring vessel, get an amount of medium and fill this container, then measuring media is poured out, the core that will measure its volume is put into measuring vessel, again the measuring media of pouring out is reinstalled in the container, must be left a part of measuring media after filling container, quality with remaining this part measuring media of electronic balance weighing, if claim quality be M, the density of measuring media is p, then the volume of tested core is:
V＝M/p （1）
In the formula: the unit of M is g; The unit of p is g/cm
3; The unit of V is cm
3
According to second purpose of the present invention, be by a kind of suitable measuring media is provided, measuring media filling and placing unit, the commercially available precise electronic balance of adapted constitute that the arbitrary-shaped core volume measuring instrument realizes.
This measuring media must be that magnetic is less, wear-resisting, anticorrosive, spherical in shape shape, and good fluidity, granularity is certain, the metal powder that apparent density is determined.Satisfied the degree of accuracy that these conditions can guarantee cubing.
The measuring media filling and placing unit is assembled by assembly processes such as bracing frame, funnel, media Containers, backstay, row end valves.
Electronic balance selects for use commercially available sensibility reciprocal to be not more than 1mg, and the electronic balance with standard binary code output gets final product.
According to the 3rd purpose of the present invention, directly read the volume of measurement, the method that prints measurement report is, the binary code of balance output is sent in the computing machine, computing machine realizes showing or printing the volume and the measurement report of measurement by display and printer under vertical application control.
Fig. 1 implements the present invention's second purpose, the overall construction drawing of arbitrary-shaped core volume measuring instrument.
Fig. 2 is the hardware system figure that implements the 3rd purpose of the present invention.
Fig. 3 is a dedicated software architecture block diagram of implementing the 3rd purpose of the present invention.
Referring to Fig. 1, loam cake at electronic balance 9 is fixed with the measuring media filling and placing unit, media Containers is fixed on the bracing frame 4 with left backstay 14 and right backstay 5, and media Containers divides up-per semi-tank 10 and second container 13 two parts, with thread connection to just constituting a complete media Containers altogether.Container top has an aperture can enter measuring media, but the bleed valve 6 of a discharge medium is arranged at the bottom, and the top of bracing frame 4 also has a funnel 1, and the aperture centering that enters measuring media of bell mouth and container top is convenient to the measuring media of packing into like this in container.
Realize that core volume measuring instrument principle of work of the present invention and method of operating can be illustrated by Fig. 1.
Referring to Fig. 1, instrument is put as accompanying drawing 1, and electronic balance is in normal operating conditions, with backstay 5,14 media Containers 15 is transferred to position with bell mouth centering.
Get an amount of measuring media and slowly pour funnel into, till measuring media inflow media Containers 15 overfills.At this moment, the electronic balance zero clearing once.Unclamp powder-placing valve 6 then, measuring media flows in the powder-holding dish 8, treat remaining a small amount of measuring media in the container, tighten powder-placing valve 6, back out up-per semi-tank 10, tested core 12 is put into second container 13, the up-per semi-tank 10 of screwing on, the measuring media of getting in the powder-holding dish is attached to the media Containers from funnel 1, fills up to container.Then with m divided by the loose specific weight of measuring media promptly get the volume of tested core if the quality that electronic balance shows is m this moment. and unclamp powder-placing valve 6, emit measuring media, back out up-per semi-tank 10 and can take out tested core.
Referring to Fig. 2, computing machine 18 is adopted back the medium of weighing through digital quantity input/output converter 16 from the binary code delivery outlet of electronic balance 9, under special software control, calculates measurement result automatically, and on screen 17, demonstrating measurement result, printer 19 prints its measurement report.
Referring to Fig. 3, the structrual description of special software is such, starts computing machine, calls in specific program, begins to measure.The staff is initial parameter such as input measurement date, standard specimen numbering at first, whether point out you revise the apparent density of measuring media, do not revise and then be default value, is is computing machine reresented and adopted back the weighing value? after confirming, the staff adopts back the weighing value, by formula automatically (1) calculates the volume of tested core, measurement result demonstrates on screen, point out you also will measure once more? measure and then continue to measure next standard specimen, otherwise printer goes out result's report of whole measurements automatically by certain format print.
Basic thought of the present invention and illustrated embodiment have more than been narrated; because principle of the present invention is simple; structure is simple and clear; the person skilled in the art will understand a little; under spirit of the present invention, can make many changes, protection scope of the present invention is determined by additional claims and coordinator thereof the present invention.
