Embodiment Construction

[0029] The present invention is described further below:

[0030] Such as figure 1 As shown, this visual sandblasting model for oil displacement experiments includes a glass slide 1 and a glass cover slide 2. The center of the inner surface of the glass slide 1 is provided with a square groove for accommodating a cemented layer of quartz sand. Layer 3 adopts compressed air to carry the cementing agent and quartz sand, and sprays it with high-speed gas in the square groove in the glass slide 1. The thickness of the quartz sand cement layer 3 is the same as the depth of the square groove in the glass slide 1; the glass cover 2 The size is the same as that of the glass slide 1, and the glass cover 2 and the glass slide 1 are bonded and formed by silicone sealant; the injection and production port designed according to the well pattern runs through the glass cover 2 and the quartz sand cement layer 3, and the injection and production port It is connected with the indoor injection...

Abstract

The invention relates to a visual sand blasting model used for oil displacement experiments and a manufacturing method thereof. The visual sand blasting model used for oil displacement experiments comprises a glass slide and a cover glass. The center of the inner surface of the glass slide is provided with a square groove holding a quartz sand cemented layer. The quartz sand cemented layer uses compressed air to carry cemented agent and quartz sand, and is formed by spraying the cemented agent and the quartz sand in the square groove in the glass slide through high-speed gas. The thickness of the quartz sand cemented layer is the same with the depth of the square groove of the glass slide. The size of the cover glass is the same with the size of the glass slide. The cover glass and the glass slide are cemented and formed by a silicone sealant. The cover glass and the quartz sand cemented layer pass through an injection and production port designed by a well pattern. The sand blasting process completely overcomes defects of surface fluid channeling of various models, and realizes uniformity of permeability and uniformity of thickness of a single-layer sand blasting layer.

Description

technical field [0001] The invention relates to a model used for studying physical displacement effects and evaluating various chemical additives in the process of oil and gas field development, in particular to a visual sandblasting model for oil displacement experiments and a manufacturing method thereof. Background technique [0002] At present, the models used to study the physical displacement effect and evaluate various chemical additives in the process of oil and gas field development mainly include: ① Natural cylindrical cores drilled from formations and artificial strip and slab cores are currently widely used in indoor An important means of physical simulation. The advantages are: high mechanical strength, can withstand high temperature and high pressure, and low cost. The disadvantages are: the displacement process is not visible, image analysis cannot be performed, and problems in the experiment cannot be accurately judged in real time; ②The microscopic glass et...
