[0004] However, no matter which method is used in the above-mentioned prior art, the permeability of the obtained sand layer is usually above 2D (Darcy), which can only simulate the displacement effect of high (ultra-high) permeability reservoirs, and cannot simulate Simulate real reservoir conditions that meet the displacement effect of medium permeability (50-500mD) or low permeability (<50mD) reservoirs

[0083] The non-spray port 31 part of the liquid spray pipe 3 is a liquid injection pipe 32, and the liquid spray pipe 3 has a plurality of the liquid spray ports 31, and each of the liquid spray ports 31 is connected with the liquid injection port respectively. The tube 32 communicates.
[0084] It can be understood that the liquid injection pipe 32 communicates with each of the liquid injection ports 31, and the inner diameter of the liquid injection pipe 32 is larger than the inner diameter of the liquid injection port 31, and may even be the diameter of the liquid injection port 31. Several times to dozens of times of the inner diameter, so that when the liquid is injected into the liquid injection port 31 through the liquid injection pipe 32, the liquid can be concentratedly injected from the liquid injection port 31 due to the greatly reduced inner diameter.
[0085] The distribution of the liquid injection ports 31 on the working surface of the hammer head 21 can be equi...

The embodiment of the invention provides a hydraulic sand shaking device, a hydraulic sand shaking system and method applied to a sand-packed model. The hydraulic sand shaking device comprises a container, a sand hammer, and a liquid spraying tube, wherein a sand accommodating cavity is formed in the container; the container is provided with a liquid discharge hole which communicates with the sandaccommodating cavity; the sand hammer is provided with a hammer head positioned in the sand accommodating cavity; the liquid spraying tube is provided with a liquid spraying hole in the sand accommodating cavity; and the hammer head and the liquid spraying hole are movably matched with the container in the vertical direction. The hydraulic sand shaking device can effectively compact the sand layer, so that permeability of the compacted sand layer is greatly reduced, and therefore, the compacted sand layer can simulate a true oil deposit condition.
Description
technical field [0001] The invention relates to the technical field of oil field development, in particular to a hydraulic sand shaking device, a hydraulic sand shaking system and a method applied to a sand filling model. Background technique [0002] In the physical simulation experiment of the reservoir, the sand-packing model is easy to make and observe. The permeability of the sand layer is obtained by filling the sand in the sand-packing model to simulate the displacement effect of the reservoir. In addition, the sand filling method in the sand filling model is usually to mix the washed and dried (or certain tidal) sand evenly according to a certain size ratio, and then gradually add it to the sand filling model. However, due to the simulation accuracy requirements , not only adding sand to the sand-packing model, but also compacting the sand layers added to the sand-packing model, and which device to use for compaction has become a research topic in reservoir physical ...
