Fracturing fracture monitoring-based low-permeability stratum pollution remediation method
The invention belongs to the field of polluted soil and underground water remediation, and relates to a low-permeability stratum pollution remediation method based on fracturing crack monitoring, which comprises the following steps: 1) constructing an injection well in a low-permeability pollution plume stratum; (2) an injection machine tool is installed in the injection well, and the injection machine tool is communicated with a high-pressure injection system located on the ground; 3) arranging inclination angle measuring equipment on the surface of the low-permeability pollution feather stratum; (4) a fracturing agent is injected into the low-permeability pollution plume stratum through a high-pressure injection system and an injection machine, and fractured fractures are formed; (5) after the fractured fracture is developed, the development condition of the fractured fracture is obtained through inclination angle measuring equipment; and (6) according to the development condition of the fracturing fractures, repairing functional materials are injected into the fracturing fractures at low pressure, and low-permeability stratum repairing is completed. According to the low-permeability stratum pollution remediation method based on fracturing fracture monitoring, the transmission efficiency of the agent can be improved, secondary pollution can be reduced, and the remediation range and the remediation boundary of the agent can be accurately identified.
本发明属于污染土壤和地下水修复领域，涉及一种基于压裂裂隙监测的低渗透地层污染修复方法，包括：1）在低渗透污染羽地层建设喷注井；2）在喷注井内安装喷注机具，并将喷注机具与处于地面的高压注射系统相连通；3）在低渗透污染羽地层地表设置倾角测量设备；4）通过高压注射系统以及喷注机向低渗透污染羽地层中注入压裂剂，形成压裂裂隙；5）待压裂裂隙发育完成后，通过倾角测量设备获取压裂裂隙的发育情况；6）根据压裂裂隙的发育情况，在压裂裂隙中低压注入修复功能材料，完成低渗透地层修复。本发明提供了一种能提高药剂的传输效率、可减少二次污染以及可精准鉴定药剂修复范围及修复边界的基于压裂裂隙监测的低渗透地层污染修复方法。
