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.
