A rock core oil washing instrument capable of automatic sampling and detection

Abstract

A rock core oil washing instrument capable of automatic sampling and detection is disclosed, belonging to the field of rock core oil washing instruments. The instrument includes an oil washing instrument support. The upper end of the oil washing instrument support is fixedly connected to a solvent chamber, an ultrasonic wave control system and an electrical appliance control system. A unique sampler having multiple layers can be mounted in the rock core chamber, and is provided with oil-in-water sensors, a sample is stored in one of the layers after each time of washing, samples of a pluralityof times of washing are stored in the multiple layers, and each layer is detected automatically by utilizing the oil-in-water sensors after sampling, and an alarm is automatically given after a requirement is satisfied, indicating that crude oil washing of a rock core meets a standard. One time of sampling is not needed for each time of washing, thus reducing the number of times of sampling, andreducing the working load of workers. Sample detection can be performed directly in the sample storage layers, thus ensuring that the whole experiment is in a sealed environment and does not cause organic solvent steam leakage which influences human body health.

Description

technical field [0001] The invention relates to the field of core oil washing instruments, in particular to a core oil washing instrument capable of automatic sampling and detection. Background technique [0002] The core oil washing instrument is an ultrasonic rapid oil washing device. When using it, put the sample into the core basket and put it into the core chamber together. Add an organic solvent with a strong ability to dissolve crude oil into the solvent chamber, and heat it to its boiling point to evaporate, and the vapor rises. Entering the condensation chamber, the steam condenses and drops into the liquid collection chamber. At this time, the liquid inlet solenoid valve is normally open, and the liquid outlet solenoid valve is normally closed. Therefore, the liquid in the liquid collection chamber directly flows into the core chamber and soaks the core. When the liquid in the core chamber fills the core chamber (as can be seen from the liquid level gauge in the li...

AI Technical Summary

Problems solved by technology

[0003] However, sampling is required after each cleaning, or multiple sampling is required, and it is cumbersome to perform detection and analysis after each sampling, and the core chamber needs to be opened for each sampling, which will cause leakage of organic solvent vapor and affect human health
