Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
It should be noted that, without conflict, the embodiments of the present utility model and features of the embodiments may be combined with each other.
Referring to fig. 1-3, a well-sealing capsule, comprising: the bag body 1 is fixedly provided with a plurality of feeding ports which are used for connecting different pipelines, and the feeding ports are used for guiding different media into the bag body 1 so that the state of the bag body 1 can be controllably changed.
The number of the feeding holes is at least two, the feeding holes comprise a first feeding hole and a second feeding hole 2, and the first feeding hole is connected with a pipeline 3.
The first feed inlet is fixedly connected with a material guiding pipe, and the material guiding pipe is positioned in the bag body 1.
The pipeline 3 can penetrate through the guiding pipe into the bag body 1, and can be clamped on the first feeding hole, so that slipping is avoided.
The second feed inlet 2 is connected with an aeration conduit and can be used for filling partial gas into the capsule body 1 so as to enable the capsule body 1 to expand relatively quickly.
The other end of the pipeline 3 is connected with a guniting device 4, and cement slurry 5 in the guniting device 4 enters the inside of the bag body 1 through the pipeline 3.
The bag body 1 comprises a first state and a second state, wherein the first state is a low internal pressure state, the second state is a high internal pressure state, when the bag body 1 is in the first state, the outer wall of the bag body 1 is not attached to a depressurization well, at the moment, little or no cement slurry 5 is in the bag body 1, and the bag body 1 can be conveniently plugged into a filter tube through the water flushing port 6.
The depressurization well includes: the water flushing device comprises a water flushing port 6, a bottom plate 61, a clay ball 62, a filter material 63 and a filter tube, wherein the bottom plate 61 is in sleeve joint fit with the water flushing port 6, the clay ball 62 and the filter material 63 are filled between the filter tube and the pit wall, and the water flushing port 6 is positioned at the upper end of the filter tube.
