Deep-layer pressure-bearing artesian well plugging system and method
The invention belongs to the technical field of underground water monitoring, and particularly relates to a deep-layer pressure-bearing artesian well plugging system and method. The method adopting the deep-layer pressure-bearing artesian well plugging system for plugging includes the steps of installing a hydrostatic column, manufacturing flange plates, installing the flange plates, performing filling of biology expanding materials, performing temporary plugging and drainage pressure reducing after a pipe is lowered, calculating the usage amount of cast cement paste and injecting the cement paste through paste injecting pipes, so that layering water-stopping end openings are formed, and permanent layering water stopping is completed. The deep-layer pressure-bearing artesian well plugging method is simple in construction, easy to implement and low in cost, it is avoided that due to large pressure borne by a pressure-bearing artisan well, the cement paste used for layering water stopping flows or breaks through the cement paste, it is prevented that because the cement can not be solidified within allowed time, layering water stopping fails, permeability of underground water is stopped, it is avoided that the underground water on the bottom layer enters a water-bearing stratum on the upper layer along a fracture surface, so that crossing of the water-bearing stratum occurs, and permanent plugging water stopping is achieved.
