Abstract

The invention proposes a fusion method for preparing silicate grass-based geological cavern man-made physical model; the steps of the preparation are as follows: 1) galena ores are broken up, ground and screened and forms micro-sized galena particles; 2) a silicate plate glass is cut into the silicate plate glasses in proper sizes which then are cleaned up and dried; 3) the micro-sized galena particles are placed among the silicate glass blocks; then the silicate glass blocks together with the micro-sized galena particles are put into a high temperature vacuum oven; 4) when being vacuumized to be in the air pressure of 10Pa, the high temperature oven begins to be heated; when being raised to 750 DEG C-850 DEG C, the temperature of the high temperature oven is maintained for 90 minutes-120 minutes; then the silicate glass blocks together with the micro-sized galena particles are fused and taken out of the high temperature vacuum oven when the temperature of the high temperature vacuum oven is lowered to 40 DEG C-50DEG C; 5) the outlines of samples of the fusion of the silicate glass blocks together with the micro-sized galena particles are processed and polished; then the silicate grass-based geological cavern man-made physical mode is formed. The invention takes a high wave speed silicate glass as a base body and takes a high wave speed natural galena as cavern simulation sundries, which conforms to the practical conditions of geology that the wave speed of the base body is high and the wave speed of the cavern is low.

Description

The smelting method for preparing silicate glass base geological hole artificial physical model

Technical field

The present invention relates to be used for the preparation method of ultrasound wave geologize hole artificial physical model, particularly relate to the preparation method that geology oil gas preserves hole artificial physical model.

Background technology

Hole, solution cavity are common in rock, and hole, solution cavity are the important space that the underground fluid water, oil, gas preserve migration.Thing ultrasound wave physical model principle be simulation under the geologic condition rock and the hole of the inside, model-based n-body simulation n rocky condition normally, and the hole among central hole or the doping granule simulation rock.Utilize the hole physical model of manual manufacture, by the dynamics and the kinematics character of seismic wave propagation in the different hole density models of ultrasound wave experimental observation.From the synthetic study that utilizes physical model experiment and supporting basic geology thereof and some special analysis means, obtain reliable news, thereby be reservoir and pool description and prediction, improve and explore success ratio the part important evidence is provided, help seismic exploration practically.

In actual geology rock, the velocity of wave of rock is greater than the velocity of wave of hole.According to similarity criterion, hole foreign material analogue body size is more little, and the actual geology size that then can embody is big more.Yet domestic and international research generally adopts the low macromolecular material of velocity of wave as matrix at present, and selects high metal of velocity of wave or the air that does not have velocity of wave as hole foreign material analogue body, and hole foreign material analogue body size is all bigger.

Do not see with the silicate glass at present to be that matrix, galenite are the report that hole simulation foreign material system is equipped with the geology hole artificial physical model.

Summary of the invention

The preparation method of described silicate glass base matter hole artificial physical model, carry out according to the following step:

1), galenite ore reduction, grinding, screening are obtained micron-sized galenite particle, selects the galenite particle of 15 μ m, 30 μ m, 50 μ m, 100 μ m, 150 μ m, 280 μ m for use;

2), silicate sheet glass is cut into suitable size, and clean up, dry;

3), 1-15 grain micron order galenite particle is placed between the silicate glass piece, put into vacuum high temperature furnace again;

4), vacuum high temperature furnace be evacuated to begin when being lower than 10Pa to heat up, rise to 750 ℃-850 ℃, be incubated 90 minutes fusion in-120 minutes, taking-up when waiting to be cooled to 40 ℃-50 ℃;

5), the sample of fusion that step 4) is obtained carries out sharp processing, polishing, promptly makes silicate glass base matter hole artificial physical model.
