Embodiment 3:
The working principle of the device of a kind of dynamic monitoring Large Underground water seal pit hole of the invention library water curtain moisturizing effect are as follows: by crack
Rock mass 8 is placed in experiment container 7, and for oil transportation tank 19 by petroleum pipeline 20 to 23 oiling of water seal petroleum hole, water curtain hole water delivery bucket 17 is logical
It crosses water-supply-pipe 16 to fill the water toward water curtain hole 25, water curtain hole 23 is delivered to water seal petroleum hole 23 weeks by the crack Jiang Shui of crack rock 8
It encloses, then increases the water pressure in about 23 water seal petroleum hole, while oil inlet pressure is adjusted by computer regulated pressure-control valve 21
With influent pressure, so that the size of oil pressure in discharge pressure and water seal petroleum hole 23 is analyzed by computer, when water pressure is greater than
When oil pressure, then it can prevent petroleum from revealing, meanwhile, after the water recycling that the rainwater-collecting bucket 18 of setting flows out aqueduct 13,
In re-injection experiment container 7, by repeatedly by produced-water reinjection, analyzing reinjected water to the infiltrative influence of cave depot rock 23, and
Influence to cave depot moisturizing systems stabilisation, meanwhile, the Water quality detector 10 of setting analyzes the water quality of reinjected water, setting
Microseism wave detector 28 is able to detect shadow of the crack in crack rock 8 under water filling repeatedly and different hydraulic pressure operating environments
It rings, time space distribution when according to rock rupture may infer that the development trend of its gross fracture, judge that potential disaster is living
Dynamic rule prevents the grease occurred during oil exploitation in reality connection, occurs to realize the early-warning and predicting of calamity source
Water logging, water breakthrough phenomenon.
The foregoing is only a preferred embodiment of the present invention, but scope of protection of the present invention is not limited thereto,
Anyone skilled in the art in the technical scope disclosed by the present invention, according to the technique and scheme of the present invention and its
Inventive concept is subject to equivalent substitution or change, should be covered by the protection scope of the present invention.
