Light path system for oil rock specimen analysis centrifuge

Abstract

The invention discloses a light path system for an oil rock specimen analysis centrifuge. The light path system comprises a stroboscope lamp, a triple prism, multiple pieces of quartz glass and a light transmitting tank, wherein the triple prism is arranged on a triple prism fixing frame; the triple prism fixing frame is arranged on a cabin door of a centrifugal chamber; the part of the triple prism fixing frame, which is in contact with the triple prism, is provided with the light transmitting tank; the stroboscope lamp is arranged below the bottom surface of the centrifugal chamber; the cabin door and the bottom surface of the centrifugal chamber are respectively provided with one piece of quartz glass; the light transmitting tank is arranged at the front end or the rear end of a centrifugal cup; and the positions of the stroboscope lamp, the triple prism and the quartz glass correspond to each other up and down. The light path system can be used for continuously monitoring the variation of oil-water interface in a liquid collecting cup, the ray direction can be changed by using the triple prism so as to change the placing position of a camera, thus reducing the altitude of the centrifuge, and enabling the operation to be convenient and the centrifuge to be sable.

Description

technical field [0001] The invention relates to the field of rock sample analysis, in particular to an optical path system for a petroleum rock sample analysis centrifuge. Background technique [0002] Petroleum resources occupy an extremely important position in the national economy and people's livelihood, and are indispensable resources for social development and human survival. With the rapid development of industry, the growth of population and the improvement of people's living standards, energy shortage has become a worldwide problem, and more and more countries pay attention to energy security. [0003] At present, in the exploration and development of oil fields, it is necessary to analyze the sampled rock samples to provide a theoretical basis, and one of the most important rock sample analysis items in the rock sample analysis is the determination of the rock capillary pressure curve. When immiscible two-phase fluids contact each other in the rock void, the press...

AI Technical Summary

Problems solved by technology

[0004] The method of measuring the capillary pressure curve of rock samples is mainly the centrifuge method, but at present, most centrifuges must stop the centrifuge at regular intervals when measuring the capillary pressure curve of rock samples, and then observe the fluid capacity discharged from the rock samples. This approach is less efficient and has larger errors

However, some centrifuges with strobe devices are usually larger in volume. Although it is not necessary to stop the centrifuge when observing the fluid capacity discharged from the rock sample, it is not convenient to use due to its large volume.
