Problems solved by technology

It brings a lot of inconvenience to field sampling and sample transportation, and it is also very easy to cause damage to the sample packaging, which directly affects the reliability of sample quality.
When oil and gas geochemical exploration samples are tested for oil and gas geochemical information indoors, it is sometimes necessary to classify and transfer the samples again for different testing items. The process is complicated and easily causes sample pollution and component escape.
The adverse effects brought about by the backwardness of sample storage methods have become more and more obvious

Embodiment 1

[0018] Embodiment 1-solid sample sampling storage and analysis method:

[0019] 200ml of saturated saline is pre-filled in the sampling bottle body 1. After the solid sample is collected, it is quickly filled into the bottle to a certain level on the liquid level (unified volume between each parallel sample), and the bottle cap 2 and the sealing cap 3 are screwed on for sealed storage (such as sample need to keep fresh, add ice or store in a freezer), transport to the room, first use a micro sampler to take a top gas sample through the sampling port 4 for headspace air analysis, then perform solid phase microextraction analysis, then perform physical adsorption gas analysis, and finally put The solid sample in the sampling bottle is poured out, the brine is filtered out, dried and crushed, and then the projects such as adsorption silk, altered carbonatite, acidolysis hydrocarbon, pyrolysis hydrocarbon, fluorescence, ultraviolet, carbonate, trace elements, ferrous iron, etc. an...

Embodiment 2

[0020] Embodiment 2-solid sample sampling storage and analysis method:

[0021] 200ml of saturated saline is pre-filled in the sampling bottle body 1. After the solid sample is collected, it is quickly filled into the bottle to a certain level on the liquid level (unified volume between each parallel sample), and the bottle cap 2 and the sealing cap 3 are screwed on for sealed storage (such as sample Need to keep fresh, add ice or store in a freezer), transport to the room, first use a micro sampler to take a top gas sample through the sampling port 4 for headspace analysis, then perform solid phase microextraction (or adsorption wire) analysis, and then perform physical adsorption Gas analysis; at the same time, quickly load the collected solid sample in another sampling bottle body 1 (the weight can be unified among parallel samples), screw on the bottle cap 2 and seal it for preservation (if the sample needs to be kept fresh, add ice or use a freezer Preservation; if fideli...

Embodiment 3

[0022] Example 3-liquid sample collection, preservation and analysis:

[0023] Quantitatively collect liquid samples and put them directly into the sampling bottle body 1, screw on the bottle cap 2 and the sealing cap 3 for sealed storage (if the sample needs to be kept fresh, add ice or store it in a freezer), transport it to the laboratory through the sampling port 4 and use a needle tube Liquid samples were taken for instrumental analysis of each analysis item.

Abstract

The invention discloses a sealed sampling bottle. The sampling bottle which comprises a bottle body (1) and a bottle cover (2) is characterized in that there are a threaded connection and a seal between the bottle body (1) and the bottle cover (2); the bottle cover (2) is provided with sampling ports (4) which are respectively provided with a sealing cover (3), and each of the sampling ports (4) has a threaded connection with one sealing cover (3); and the sealing cover (3) of each of the sampling ports (4) is provided with a through hole, and a sealing gasket is arranged between one sampling port (4) and one sealing cover (3) to seal. By adopting the sampling bottle of the invention to preserve gases, liquids and solids, the sealing effect is good, so the adoption of a unified preservation mode of different detection projects of a same sample is realized, intermediate links from an acquisition phase to a detection phase of the sample are shortened, and the reliability and the validity of analysis data are practically improved.

Description

technical field [0001] The invention relates to the technical field of oil and gas geochemical exploration, and furthermore, relates to a multipurpose sealed sampling device used in this field. Background technique [0002] Oil and gas geochemical exploration (abbreviation: oil and gas geochemical exploration) sample types involve different types of soil, rock, water, gas and so on. Field sampling and sample preservation are based on the "People's Republic of China Geological and Mineral Industry Standards - Petroleum and Natural Gas Geochemical Exploration Specifications" (DZ / T 0185-1997) implemented in 1998, using cellophane, kraft paper, glass bottles, plastic barrels, etc. Sample storage. Sometimes the same sample even requires multiple storage methods to meet the requirements of different testing items. It brings a lot of inconvenience to field sampling and sample transportation, and it is also very easy to cause damage to the sample packaging, which directly affects ...
