Embodiment Construction
[0034] Below in conjunction with accompanying drawing, the present invention will be further described:
[0035] Such as figure 1 As shown, this combined 3D helical perforation simulation injection device includes that this combined 3D helical perforation simulation injection device can be composed of a certain number of parts with different functions, including joint part 1, connecting part 2, perforation There are four kinds of parts 3 and tail joint 4. There is a sealing ring 5 at the upper end of each component, and a connecting hole at the lower end. The center hole corresponding to the sealing ring 5 at the top of each component has a male button, and the connecting hole has a female button, so that the parts can be connected end to end, which is convenient for disassembly and assembly. According to the perforation plan, they are connected to each other to form a combined 3D spiral perforation simulation injection device. It can be poured into the artificial rock core ...
