摘要: Disclosed is an environmentally friendly capsular bag-type downhole karst cave blocking device, relating to the field of petroleum drilling, and mainly being used block a cave. The device comprises mechanical parts, such as connecting rod, hinges (309, 310, 311), springs (407, 408), one-way valve (204), slide rail (102), sensor (405), ratchet electromagnets (402, 404) in combined transmission manner. automatic whole realized by means bag. Further disclosed method. method reduce requirements for leakage material drill pipe, costs time needed cave, can be large honeycomb-shaped carve scenarios.
