An oscillation measurement method and system for simulating the vertical grain sequence of glutenite

Abstract

The invention belongs to the technical field of testing or analyzing materials through chemical or physical nature of determination materials, and discloses an oscillation measuring method and systemfor simulating the vertical granule sequence of glutinite. The oscillation measuring system comprises an oscillator, an oscillation box, oscillation granules and a classifying sieve net, wherein the oscillation box is placed on the oscillator; the classifying sieve net is used for classifying the oscillation granules according to the particle diameter; and a water outlet with the diameter of 2cm,which is used for simulating water flowing effects actually, is formed in the bottom of the side wall of the oscillation box. According to the oscillation measuring method and system disclosed by theinvention, in the oscillation course of the selected oscillation box, all the granules and water wholly move along with the oscillation box, besides, a water drainage device in the oscillation box guarantees water body circulation in the oscillation course, and the water body circulation corresponds to the power effect of waves (lake waves) in nature on sediment, so that the oscillation effect canprovide power for the movement of all the deposition granules in the oscillation box, and further the changes of the vertical granule sequence can be determined; besides, during design, experiment scales, oscillation frequency and effect time suitable for indoor operations are selected.

Description

technical field [0001] The invention belongs to the technical field of testing or analyzing materials by means of measuring chemical or physical properties of materials, and in particular relates to an oscillation measurement method and system for simulating the vertical grain sequence of glutenite. Background technique [0002] At present, the commonly used existing technology in the industry is as follows: the vertical variation of clastic particles in sand body or single sand layer is called grain size rhythm or grain sequence, which is controlled by depositional environment and sedimentation. Grain sequences are generally divided into four categories: positive, reverse, compound, and homogeneous. Multiple sequenced layers are superimposed vertically to form a sedimentary cycle, which plays an important role in stratigraphic division and correlation, determination of sedimentary mineral horizons and their formation environments, analysis of sedimentary facies, and judgmen...

AI Technical Summary

Problems solved by technology

[0003] To sum up, the problems existing in the prior art are: in the variation of the grain order of the coarse-grained sediments in the vertical direction, the gravel in the flume experiment has a coarse particle size, which requires a strong moving force; the flume experiment is difficult or unable to provide enough water. Dynamic conditions; the purpose of the tank experiment is to observe the evolution process and characteristics of each sedimentary facies from the plane. If you want to observe the vertical phenomenon, you need to stop the experiment and cut the section for analysis, which will affect the experimental results, so it is difficult to reflect the sediment in real time change in vertical
