AI Technical Summary

Technical Problem

The existing rock heating desorption system is difficult to adapt to the desorption requirements of cores of different specifications, and there are problems such as void volume expansion affecting the reliability of the desorption curve and difficulty in mud separation.

Method used

A rock heating desorption system was designed, which used an elastic sleeve and the inner wall of the desorption tank to form a sealed space, combined with a pressure relief device and a compression mechanism to reduce the empty volume, and achieved mud separation through a liquid receiving device and a condensate collection device.

Benefits of technology

It realizes the convenient canning of cores of different specifications, reduces the influence of empty volume, improves the reliability of desorption curve, and effectively separates the heated and melted mud.

Abstract

The invention relates to the field of oil-gas exploration, and discloses a rock heating desorption system, a rock heating desorption method, a medium and electronic equipment. The system comprises a rock core desorption tank used for bearing a rock core sample; the sample pressing device covers the inner wall of the rock core desorption tank, so that a closed space is formed between the sample pressing device and the inner wall of the rock core desorption tank, and the sample pressing device is tightly attached to the rock core sample under the pressure action of the closed space; the pressure increasing and relieving device is communicated with the closed space in the rock core desorption tank and is used for executing pressurizing operation on the closed space to increase the pressure of the closed space so as to drive the sample pressing device to press the rock core sample; the gas collecting device is communicated with the rock core desorption tank and is used for collecting gas generated in the rock core desorption tank. Rock samples of different specifications can be desorbed, and separation of slurry after heating and melting can be achieved.
