Embodiment 1

[0028] Such as Figure 1 to Figure 3 As shown, the present invention provides a microfluidic observation experimental device, comprising: a chip position for placing a rock chip test model 1, an image acquisition device 5 is installed around the chip position and directly above the chip position; The acquisition device 5 is suitable for photographing the distribution and flow conditions of the multiphase fluid in the rock slice test model.

[0029] The image acquisition device 5 is for example but not limited to a CCD image sensor, figure 1 The dotted line in the image acquisition device 5 indicates the shooting range of the image acquisition device 5 .

[0030] Specifically, the rock slice test model includes: a transparent chip 100, which is provided with a number of sequentially arranged recesses suitable for embedding corresponding imitation rock core slice samples 101, and the corresponding flow channels 102 are passed between each recess. Connected in sequence, wherein...

Embodiment 2

[0040] On the basis of Example 1, this Example 2 also provides a working method of a microfluidic observation experimental device.

[0041] The working method includes: injecting test solution into the rock slice test model to photograph the distribution and flow conditions of the multiphase fluid in the corresponding microscopic pores in each imitation core slice sample in the rock slice test model.

[0042] The microfluidic observation experimental device is suitable for adopting the microfluidic observation experimental device described in Example 1.

[0043] Specifically, after the heat source device and the cold source device are energized, a temperature difference is formed on the upper and lower sides of the simulated rock core slice sample to simulate the temperature environment of the underground rock formation and analyze the penetration of the fluid in the underground rock formation (fluid distribution and flow conditions) , to impel the test solution to permeate fr...

Abstract

The invention relates to a microfluid observation experiment device and a working method thereof, the microfluid observation experiment device comprises a chip position and image acquisition devices.The chip position is used for placing a rock slice test model, and image acquisition devices are arranged around the chip position and right above the chip position; and the image acquisition device is suitable for shooting the distribution and flow conditions of multi-phase fluid in the rock slice test model. Corresponding test channels are formed by embedding corresponding rock-core-imitated slice samples which are arranged in sequence; the rock-core-imitated slice samples can be correspondingly sorted according to the density degree of the microscopic pore channels in the rock-core-imitatedslice samples to realize different test manners and further meet tests for various types of core slices; distribution and flow conditions of multiphase fluid in the corresponding microcosmic channelsin the rock-core-imitated slice samples are clearly shot by the image acquisition devices arranged in different directions, so that data analysis is carried out on the rock-core-imitated slice samples.

Description

technical field [0001] The invention relates to a transparent chip of a microfluid observation experiment device. Background technique [0002] At present, my country's demand for petroleum energy is increasing day by day, and the difficulty of petroleum exploration is increasing. How to further improve the recovery rate of crude oil has become an urgent problem for scientific research workers. [0003] At present, there is no good experimental testing device for imitation rock core slice samples. [0004] Therefore, aiming at this technical problem, it is necessary to design a microfluidic observation experimental device and its working method. Contents of the invention [0005] The purpose of the present invention is to provide a microfluidic observation experimental device and its working method, which is suitable for completing the test of multiple imitation rock core slice samples, and clearly photographs the corresponding microscopic pores in the imitation rock slic...
