Embodiment Construction
[0028] Below in conjunction with accompanying drawing, the present invention will be further described:
[0029] Such as figure 1 As shown, this wrapped artificial core with different bedding angles is a true triaxial hydraulic fracturing test specimen formed by a small core wrapped in a large core. The small core 2 is a core with multi-layer bedding planes. Cylinder 3 and two short cylinders 4 form a bracket, and the bracket is wrapped in the large core 1. The two long columns 3 in the bracket are located on the left side of the two short columns 4, and the tops of the two long columns 3 and two short columns 4 are The connection line constitutes an inclined surface, and the connection line of four points where two long cylinders 3 and two short cylinders 4 are located forms a rectangle, and the distance from the left side of the rectangle to the left side of the large rock core 1 is equal to the right side The distance to the right side of the large rock core 1 is equal, an...

The invention relates to an inclusion type artificial rock core with different bedding angles and a method for manufacturing the inclusion type artificial rock core. The inclusion type artificial rockcore with the different bedding angles is a true tri-axial hydraulic fracturing experiment specimen. A small rock core is included in a large rock core to form the true tri-axial hydraulic fracturingexperiment specimen; the small rock core is a rock core with multilayer bedding planes, a support is formed by two long cylinders and two short cylinders and is included in the large rock core, the two long cylinders in the support are positioned on the left sides of the two short cylinders, inclined planes are formed by cylinder top connecting lines of the two long cylinders and the two short cylinders, the small rock core is arranged on the support in an inclined manner, and the bottom surface of the small rock core coincides with the inclined planes; a fracturing pipe is inserted into thesmall rock core from the upper surface of the large rock core. The inclusion type artificial rock core and the method have the advantage that the problem of deviation when existing artificial rock cores with structural weak planes are used for simulation experiments can be solved by the aid of the inclusion type artificial rock core and the method.
Description
technical field [0001] The invention relates to the technical field of artificial rock cores, in particular to a packaged artificial rock core with different bedding angles and a manufacturing method thereof. Background technique [0002] Tight reservoirs have extremely poor permeability, and can only be efficiently developed through volume fracturing to form a fracture network. During the deposition of tight reservoirs, structural weak surfaces such as bedding and micro-fractures develop. Field fracturing practice shows that reservoirs with well-developed structural weak surfaces Layers are more likely to form network fractures, and the fracturing effect is better. Therefore, it is of great significance to analyze the influence mechanism of structural weakness on the formation of fracture network. At present, an important means of research on this aspect is the true triaxial hydraulic fracturing experiment. Since tight reservoir cores cannot be obtained in large quantities...
