  • Patent number: 11857977
    Abstract: A fixing clamp for a microfluidic chip includes a set of sub-clamps arranged to be spaced apart on left and right. Each of the sub-clamps includes an upper plate body with a first passage, the first passage having a first outer interface and a first chip docking port, and the first chip docking port being located on a lower surface of the upper plate body and at one end of the upper plate body facing the other sub-clamp; a lower plate body with a second passage, the second passage having a second outer interface and a second chip docking port, and the second chip docking port being located on an upper surface of the lower plate body and at one end of the lower plate body facing the other sub-clamp; and a spacing adjusting mechanism connecting the upper plate body and the lower plate body together.

  • Patent number: 11148137
    Abstract: The application relates to a reservoir chip and a method for producing the same. The method includes: scanning a three-dimensional structure of a real oil reservoir core and reconstructing the three-dimensional structure, extracting pore size distribution characteristics, analyzing formation of a pore structure of the real oil reservoir core and accumulation morphology of rock particles, extracting the morphology of main large particles in the rock particles and establishing a large particle morphology database; distributing and projecting particles in a porous medium of the reservoir chip, to obtain a picture of the reservoir chip structure; importing the picture into a drawing software, and drawing import and export regions of the reservoir chip structure to obtain a design drawing of the reservoir chip; and making the design drawing etched on a substrate and bonded with a heat-resistant glass anode to obtain the reservoir chip.
