Description
Technical field
The utility model relates to petroleum gas fields of measurement, particularly relates to a kind of sphericity comparison template for fracturing propping agents.
Background technology
The effect of fracturing propping agents is the man-made fracture that filling pressure break produces, and is formed have the oil and gas flow passage of high flow conductivity on stratum, the performance of propping agent and differing greatly in the impact of Different Strata condition on the permeability of supporting crack.The sphericity of propping agent and the performance evaluation of circularity on propping agent have very important impact, are one of selecting properly and the basis using propping agent.
At present, in numerous grain size analysis method, most employing manual testing method is namely: in tested propping agent sample, take out 20 ~ 30 propping agents (particle) arbitrarily, observe under being placed on stereomicroscope and take microphoto, sphericity and the circularity of every propping agent is manually determined, finally again by average sphericity and the average roundness of vision comparison this batch of propping agent sample according to chart board.But the whole process of test is all that the eyes of experimentally member carry out judging and comparing, and so virtually there is personal error.Make the result that different people or identical people do at different time, there is very large error, data are disperseed very much, so just affect the judgement of experimental result.
Utility model content
For the above-mentioned defect existed in prior art, the utility model aims to provide and a kind ofly can, from the angle of comparison, make the comparison of sphericity be no longer only contrast intuitively, and a kind of sphericity comparison template that intuitively can contrast according to template is to solve the problems of the technologies described above.
The utility model is realized by the following technical programs:
A kind of sphericity comparison template, comprises chart board, sphericity comparison chart; It is characterized by: described chart board adopts X-ray material; The picture size of described sphericity comparison chart is 20 × 20cm; Described picture marking is in X-ray material; Described chart board transverse axis is carved with circularity scale value; The described chart board longitudinal axis is carved with sphericity scale value.
Be preferably: the picture of described sphericity comparison chart is engraved structure.
Be preferably: the picture described chart board being provided with the sphericity comparison chart described in 20 width.
Beneficial effect: the utility model achieves not only with visual contrast owing to adopting above technical scheme, and its comparing result is more accurate, simple to operate.
Accompanying drawing explanation
Accompanying drawing 1 is the structural drawing of the utility model sphericity comparison template.
Wherein: sphericity comparison chart 1, chart board 2
Embodiment
Shown in accompanying drawing 1.
A kind of sphericity comparison template, comprises chart board, sphericity comparison chart; Described chart board adopts X-ray material; The picture size of described sphericity comparison chart is 20 × 20cm; Described picture marking is in X-ray material; Described chart board transverse axis is carved with circularities; The described chart board longitudinal axis is carved with sphericity value.Owing to have employed X-ray material, sphericity comparison chart 1 is propping agent (particle) picture figure, and it is black under normal conditions, is pellucidity under sense state; Chart board 2 is pellucidity in normality, is black slightly pellucidity under sense state.
Optimal technical scheme: the picture of described sphericity comparison chart is engraved structure; Described chart board is set to the picture of 20 width sphericity comparison charts.
The course of work: under propping agent (particle) sample is placed in microscope, regulate microscope magnification, before sphericity test board being overlying on computer screen or projection, photosensitive transparent propping agent (particle) picture Fig. 1 and microscope lower support agent (particle) sample drawing in sphericity test board is utilized to compare, contrasted by the shape of propping agent (particle) the picture Fig. 1 on sphericity test template, find the figure that can substantially overlap, then sphericity sphericity test board shown is the sphericity reading of sample; Carry out next comparison, read 20-30 propping agent (particle) sample sphericity.
In order to verify the utility model comparison result accuracy, engineering technical personnel have carried out the experiment of two kinds of methods.Sample mix is evenly divided into 10 equal portions, and often kind of method tests 10 times, and its experimental result ginseng is shown in Table 1.As can be seen from two kinds of methods experiment data, the standard variance of employing the utility model experimental result and extreme difference value, all significantly lower than the result judged with human eye, illustrate that new method of testing collimation, repeatability are all relatively good.
Table 1
Set forth a lot of detail in the above description so that fully understand the utility model.But above description is only preferred embodiment of the present utility model, the utility model can be much different from alternate manner described here to implement, and therefore the utility model is not by the disclosed concrete restriction implemented above.Any those skilled in the art are not departing under technical solutions of the utility model ambit simultaneously, the Method and Technology content of above-mentioned announcement all can be utilized to make many possible variations and modification to technical solutions of the utility model, or be revised as the Equivalent embodiments of equivalent variations.Every content not departing from technical solutions of the utility model, according to technical spirit of the present utility model to any simple modification made for any of the above embodiments, equivalent variations and modification, all still belongs in the scope of technical solutions of the utility model protection.
