Non-crosslinking special gel leakage stopping method

The invention relates to a non-crosslinking special gel leakage stopping method. The method is characterized in the a polishing drilling rod is feed in 20 to 30m the top part of a leaking layer; a drilling tool moves up and down; non-crosslinking special gel leakage stopping slurry is prepared through a clean slurry tank, wherein the non-crosslinking special gel leakage stopping slurry is prepared from water, a special gel ZND-2 leakage stopping agent, a gel fiber leakage stopping agent and a rigid wedging type leakage stopping agent; 0.8 to 1.6 parts by weight of special gel ZND-2 leakage stopping agent, 5 to 8 parts by weight of gel fiber leakage stopping agent and 10 to 15 parts by weight of rigid wedging type leakage stopping agent are added to 100 parts by weight of water; all components are fully agitated and mixed, and then the non-crosslinking special gel leakage stopping slurry is immediately poured into the leaking layer in a well to statically stop the leakage for 4 to 8 hours. The method is simple to construct; the bearing capacity of a plug at the special gel section can be improved; in addition, the bridge-plugged leakage stopping materials can be prevented from being diluted and flushed way by formation fluid, and therefore, the success rate of leakage stopping can be increased.
