Method of isolating contaminated geological formations, soils and aquifers |
摘要 |
A method of isolating a contaminated geological formation or aquifer is disclosed in which the formation is encapsulated by impermeable barriers. A grid of wells is drilled into the formation. A horizontal barrier is formed below the contaminated formation by creating an overlapping pattern of horizontally-oriented fractures filled with polymer radiating from each of these wells. A horizontal barrier may also be formed above the top surface of the contaminated formation if necessary. A ring of boundary wells may also be drilled surrounding the contaminated formation. The strata around each boundary well are fractured, and a polymer is then injected to form a vertical barrier around the periphery of the contaminated formation. In addition, water may be injected under pressure into guard wells between the contaminated formation and the vertical and/or horizontal barriers to further reduce any migration of pollutants into neighboring formations.
