Background
With the continuous development of oil fields, formation sand can gradually flow into the bottom of a well along with the production of crude oil, and particularly the problem is more serious for unconsolidated sandstone formations. As formation sand is produced, a depletion zone occurs near the bottom of the well. Causing the phenomenon that the well hole is sand-blocked or the production pipe column is sand-buried. In order to ensure the normal production of an oil well, gravel is usually filled between a stratum borehole and a casing which is lowered into the stratum borehole, or materials such as resin sand are filled, a gravel artificial borehole wall with certain strength and permeability or an artificial borehole wall formed by cementing the stratum sand and the resin sand is formed outside the casing, so that oil layer sand is prevented from flowing into the borehole, the oil and sand introducing and blocking effects are achieved, meanwhile, the stratum is supported, and the collapse of the stratum borehole is prevented.

The device belongs to a large-scale actual-size gravel sand prevention simulation experiment device and is provided with a transparent simulation shaft, wherein the outer diameter of the shaft is 200mm, the inner diameter is 160mm, and the total length is 30 m. A87 mm wire-wrapped screen pipe, a flushing pipe and a gravel packing tool combined pipe column are assembled in the shaft, and gravel is filled in the simulated shaft through a water supply centrifugal pump, a mortar stirring tank and a sand pump. However, the known test device can only carry out the horizontal well gravel pack sand control simulation test in a normal temperature state, and cannot realize the simulation test function of artificial well wall sand control formed by cementing formation sand and resin sand.
