Embodiment 1

[0022] A pore template for observing fluid flow in porous media, characterized in that: there are pores in the pore template 4, and the range of the pores is between 0.05-0.1 mm, and there are four ports around the pore template 4, and the four ports pass through the shell The body arm is introduced and communicated with the side of the aperture template 4 through the buffer zone. The four ports constitute a fluid inlet and a fluid outlet. The pressurized fluid flows through the inlets in the pores of the aperture template 4 and flows out from the outlet.

Embodiment 2

[0024] Such as figure 1 As shown, an aperture template for observing fluid flow in porous media, the housing includes a front cover 1 and a bottom plate 7, the middle of the front cover 1 is a circular observation cavity, and the observation plate 2 passes through the sealing ring 3 and the front cover 1 The circular observation hole is sealed, the observation plate 2 is made of transparent material, the aperture template 4 is fixed parallel to the back of the observation plate 2, the aperture template 4 is pressed tightly by the observation plate 2 and the back pressure mechanism, so that there is no gap between the aperture template 4 and the front end observation plate 2, The rear end of the back pressure mechanism is connected with the bottom plate 7 through the first screw 8, and the front cover 1 is connected with the back pressure mechanism through the second screw 9, so that the aperture template 4 is sealed.

Abstract

The invention relates to a small opening pattern plate used for observing fluid flow in a porous medium. The small opening pattern plate is characterized in that the small opening pattern plate is provided with small openings. Range of the small openings is between 0.05 millimeter and 0.1 millimeter. Four openings are formed on the periphery of the small opening pattern plate. The four openings are guided in through a shell body arm and communicated with the side face of the small opening pattern plate through a buffering belt. A fluid inlet and a fluid outlet are formed by the four openings. Pressured fluid flows in the small openings of the small opening pattern plate through the fluid inlet, and flows out from the fluid outlet. The small opening pattern plate used for observing fluid flow in the porous medium is arranged in the porous medium and observable in high pressure and low temperature (or high temperature) states. The small opening pattern plate is used for observing, simulating and analyzing fluid flow states of oil, water, gas, foam and colloid in the porous medium.

Description

technical field [0001] The invention relates to the field of reservoir engineering, in particular to a pore template for observing fluid flow in porous media, and for observing, simulating and analyzing the fluid flow states of oil, water, gas, foam and colloid in porous media. Background technique [0002] In petroleum engineering, especially in the field of reservoir engineering, observing and analyzing the fluid flow state of oil, water, gas, foam, and colloid in porous media, or the movement and diffusion reactions of microorganisms in porous media, is very important for understanding formations. The macroscopic appearance and characteristics of oilfields play an important guiding role, and in-depth research can provide more intuitive reservoir information for multiple oilfield recovery. [0003] Fluid flow in porous media is mostly observed through microscopic methods. The equipment used is also similar. At this stage, most of the experimental equipment at home and ab...
