Problems solved by technology

The synthesis method of fluid inclusion standard samples is very difficult technically and requires high equipment, all of which need to be carried out under high pressure and high temperature in an autoclave, and the shape of the formed inclusions is not easy to control, and the phase state of the inclusion fluid is unstable, thus affecting clear observation and application
In addition, whether it is the means of forming cracks or filling and sealing cracks, the operation is not easy to control, resulting in very low yield

Embodiment 1

[0027] Embodiment 1: the preparation method of pure liquid fused silica capillary inclusion

[0028] combine figure 1 As shown, it is a method of making a pure liquid fused silica capillary inclusion standard sample, that is, a pure liquid is wrapped with quartz to form a fluid inclusion standard sample. Taking water as the fluid as an example, the steps are as follows:

[0029] (1) Intercept capillary: intercept each section of quartz capillary with a length of about 50 mm, and select fused silica capillary for gas chromatography column; the intercepted capillary is in pairs, and the two lengths of each pair of capillary should be equal; for the convenience of centrifugation The centrifuge does not deflect;

[0030] (2) Burning coating: the coating on the outer surface of the capillary about 35mm away from one end of the fused silica capillary, burn the coating with the outer flame of the hydrogen flame gun to remove the coating and increase the transparency of the capillar...

Embodiment 2

[0043] Such as figure 2 Shown is a preparation method of a liquid-gas fused silica capillary inclusion standard sample in which a gas-liquid two-phase fluid is encapsulated in a quartz capillary. The liquid is water and the gas is carbon dioxide as an example for illustration.

[0044] Among them, the steps （ 1)-(8) The operations of intercepting the capillary, burning the coating, sealing, cleaning the surface of the capillary, filling the fluid medium, centrifuging, stereoscopic mirror detection and vacuum extraction are the same as those in Example 1, the only difference is that the gas filling operation is added , the operation is as follows:

[0045] (9) Freezing fluid medium: cooling the liquid water in the capillary to condense into solid ice;

[0046](10) Vacuuming again: control the vacuum valve to vacuumize again, and keep it until the end of sealing;

[0047] (11) Thawing: close the vacuum valve, lower the lifting table, and let the sealed end of the fused silic...

Abstract

The invention discloses a manufacturing method of an inclusion standard sample synthesized by a fused silica capillary. The manufacturing method includes the following steps: a fused silica capillary with the length of 45-60mm is intercepted; one end of the fused silica capillary is sealed; moderate liquid is sucked in the capillary through the other end of the fused silica capillary by using the siphon principle; high-speed centrifugal processing is performed on the fused silica capillary filled with the liquid by using a high-speed centrifugal machine so as to enable the liquid to sink at the bottom of the sealed end of the capillary; refrigeration is performed, and the liquid has phase transition to be condensed into a solid state; air in the capillary is exhausted by controlling a vacuum system; and pipe sealing is performed on the open end of the fused silica capillary under the vacuum state. The manufacturing method is simple to operate, small in equipment investment, high in production efficiency and finished product rate and regular in products.

Description

technical field [0001] The invention relates to a method for preparing a fluid inclusion standard sample. Background technique [0002] The analysis of fluid inclusions is an important method in current geological research. Fluid inclusions are used in the temperature measurement calibration of hot and cold stations, the calibration of Raman spectrometers and other related instruments, as well as the phase balance and fluid reaction simulation of fluids (minerals, oil and gas, environment, geography, etc.), and the observation and simulation of chemical reactions. "Synthetic method of fluid inclusions and its significance to the study of mineral deposits" ("Minerals and Geology" 2003 No. 2, Zhang Zhenliang, Lu Xinbiao, Rao Bing) recorded the current artificial synthesis method of fluid inclusion standard samples, a The method is: artificially create cracks on the quartz in advance. The method of creating cracks includes drilling a hole in the horizontal crystallization axi...
