Loop tube jet rock core oil washing instrument

Abstract

The invention discloses a loop tube jet rock core oil washing instrument belonging to the technical field of a rock core oil washing instrument, and a loop tube jet rock core oil washing instrument comprises a base, a control panel, a waste liquid recovery room, a rock core chamber, a sealing cover, an organic solvent chamber, a liquid collection chamber and a condensation chamber, a liquid discharge pipe is connected between the organic solvent chamber and the waste liquid recovery chamber, a high pressure pump is fixedly connected to one side wall of the rock core chamber, a plurality of uniformly-distributed liquid leaking holes are arranged at the lower end of the rock core chamber, a rock core fixing seat is fixedly connected with an inner bottom plate of the rock core chamber, a rockcore body is placed in the rock core fixing seat, a loop tube matched with the rock core body is placed inside the rock core chamber, rock core ''dip bath'' washing oil in the prior art is changed to''shower'' oil washing, heating and condensation can be prepared before experiments, test time is saved, tiny bubbles are difficult to form in dried rock core channels during an oil washing process,and the oil washing effect can be greatly improved.

Description

technical field [0001] The invention relates to the field of core oil washing instruments, and more specifically relates to a ring-pipe spray type core oil washing instrument. Background technique [0002] In the petroleum scientific research industry, the oil washing instrument is an indispensable instrument for core cleaning and drying. The working principle in the prior art is generally that it is used to clean the crude oil and its solubles in the oily core. Put the sample into the core basket and put it together. Into the core chamber, 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. Normally open, the liquid outlet electromagnetic valve is normally closed, so the liquid in the liquid collection chamber directly flows into the core chamber to soak the core. Appropriate vibration to dissolve the oil to achieve the purpose of oil removal, return the solvent containing crude oil to ...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, it is necessary to heat and condense the organic solvent before soaking the core, which is carried out during the test, which will lead to low efficiency and long time, and because there are tiny pores on the core, the dry core can be soaked directly It is easy to form tiny bubbles in the pores (liquid tension phenomenon), which directly affects the cleaning effect of crude oil
