Problems solved by technology

In this process, it is necessary to connect the liquid input and output conduits with the sheet through a holder. The holder itself can be moved at will, so that the position of the glass sheet will move when the displacement fluid conduit is replaced. , resulting in large shifts and rotations of the positions of the images collected during different oil displacement periods, which will affect the subsequent image analysis. The previous displacement fluid still remains in the connector, which will affect the reliability of the displacement experimental data

Abstract

The invention discloses a sheet clamp which comprises a clamp substrate and a clamp supporting frame. The clamp substrate is arranged on the clamp supporting frame. The sheet clamp is further composed of two holders arranged on the clamp substrate. The two holders are respectively provided with a detachable liquid connector, the clamp substrate is provided with multiple glass pressing bases, and the glass pressing bases are provided with glass pressing screws. The detachable liquid connectors arranged on the holders can be replaced according to different displacing fluid, influences of residual liquid on reliability of displacement experiment data are prevented, meanwhile, a glass sheet is fixed through the glass pressing bases and the glass pressing screws arranged on the glass pressing bases so that the situation that images collected at different displacement time periods move and rotate substantially due to the fact that the sheet moves when a displacing fluid guide pipe is replaced can be avoided, and accordingly later image analysis can be more accurate.

Description

technical field [0001] The invention relates to a high-definition detail image acquisition and dynamic image continuous acquisition device, in particular to a sheet holder. Background technique [0002] In the development of oil and gas fields, especially in the research of secondary oil recovery and tertiary oil recovery, microscopic displacement experiment is an effective and visual research method. Combining the application of image processing algorithm with displacement experiment can realize the dynamic image of the displacement process quantitative analysis. Dynamic image acquisition is a very important part of the experimental process. Microscopic simulated pore glass thin slices are used in the simulated microscopic displacement experiments. Microscopic simulated pore glass thin slices are a kind of visualized physical thin slices of microscopic pores in the reservoir. From qualitative analysis to quantitative description of reservoir fluid microscopic seepage proc...
