Embodiment
Below in conjunction with accompanying drawing, structural principle of the present utility model and principle of work are described in detail.
With reference to Fig. 1, a kind of parallel board slit simulation apparatus of fracturing fluid leak, comprise imported valve 1, imported valve 1 interconnected fracture import 2, the entrance point of fracture entry 2 is provided with two pieces of poly (methyl methacrylate) plates 14, the above and below of two blocks of organic glass 14 respectively by the first strip sponge 6, second strip sponge 7 of densification as interlayer, the arranged on left and right sides of two blocks of organic glass 14 respectively by the first strip rubber sheet gasket 3, second strip rubber sheet gasket 8 as interlayer, the overall simulation fracture forming a flat-shaped cavity body structure.
With reference to Fig. 2, the upper and lower fracture plane of simulation fracture, due to leak-off, is provided with the upper end percolate collection tubes 4 and lower end percolate collection tubes 5 that are stuck with simulation fracture, collects filtrate; Upper end percolate collection tubes 4 and lower end percolate collection tubes 5 are respectively arranged with upper end filtrate pipe valve 10 and lower end filtrate pipe valve 11, the total collection tube after upper end percolate collection tubes 4 and lower end percolate collection tubes 5 gather is provided with filtrate general export valve 13, simulation fracture, the pipeline of crack outlet 9 is provided with outlet valve 12.
With reference to Fig. 3, described upper end percolate collection tubes 4 is identical with lower end percolate collection tubes 5 structure, all adopt rectangle integrated design, object is to make itself and parallel machine glass plate 14 " blocking ", rubber weather strip 15 is adopted to seal between parallel poly (methyl methacrylate) plate 14 outside and rectangle integrated design place, simultaneously, according to thickness and the quantity of padded rubber weather strip 15, the spacing of two pieces of poly (methyl methacrylate) plates can be controlled, namely can play the object regulating fracture width, finally, two pieces of poly (methyl methacrylate) plate 14 screws 16 are fixed, reach the object of fully sealing.
