Description

Rapid extraction device not limited by shale sample amount and working method thereof

Technical Field

The invention relates to the technical field of shale extraction, in particular to a quick extraction device which is not limited by shale sample amount and a working method thereof.

Background

One of the important methods for oil-gas exploration is to separate the group components of oil in shale, and then to analyze the characteristic organic compounds of various information such as deposition environment and diagenetic change by performing chromatographic mass spectrometry on the aromatic hydrocarbon. The currently common method is a soxhlet extraction method, for example, when chloroform or dichloromethane is used to extract bitumen a in shale (bitumen a is taken as an example, and then chemical dissolution is needed to remove asphaltene after bitumen a is obtained to obtain aromatic hydrocarbon substances), an extract obtained after an extraction experiment (minimum 7 days) is a mixture of oil and a reagent, and organic reagent dichloromethane is distilled and recovered to obtain bitumen a for a longer time, and an extraction device can only put down 100g of a sample, so that aromatic hydrocarbon substances obtained finally by 100g of the sample can not be subjected to mass spectrometry at all, and repeated extraction and distillation are time-consuming and labor-consuming, while in the case of oil sand with high oil content, the found problem is that too much oil is extracted by 100g of the sample (up to twenty-several g), and experiments such as separation of family components of extracted oil at the later stage do not need so much sample amount (as long as 1g of the sample amount), so much waste is caused to the design of a device which can change the oil content of the sample and can shorten the extraction volume and extract the extraction time at the later stage, and integrate the extraction with the distillation time at the earlier stage.
