The invention mainly relates to a water eggplant with a closed double-layer capsule, one capsule is arranged inside and is called as an inner capsule, the other capsule is arranged outside and is called as an outer capsule, and the capsules are provided with openings (water injection openings) capable of being filled with liquid. During use, saline water is filled into the inner capsule, so that the capsule sinks to reach the bottom of the well. After the capsule reaches the well bottom, saline water continues to be injected into the inner capsule, so that the inner capsule is expanded to occupy the volume of the water well, and flow cutoff can be achieved preliminarily when the volume of the inner capsule can occupy the water well completely. At the moment, the inner capsule is sealed, and water is injected into the outer capsule, so that the water pressure of the outer capsule is larger than that of the inner capsule, the pipe diameter of the inner capsule is reduced, and the outer capsule occupies the volume in the well. And when the difference between the water pressure in the capsule and the water pressure in the pipeline reaches a safety value. The pipeline needing to be overhauled can be pumped, and then well descending operation can be carried out.
本发明主要是一种密闭式双层胶囊的水茄子，一个胶囊在内，称为内胶囊，一个胶囊在外，称为外胶囊，胶囊带有可加注液体的口子(注水口)。使用时，先向内胶囊加注盐水，使得胶囊下沉直达井底。当胶囊到达井底后，继续向内胶囊中加注盐水，使得内胶囊扩充壮大挤占水井的体积内胶囊的体积完会占满水井时，就可以初步实现断流。此时封闭内胶囊，然后开始向外胶囊中加注水，使得外胶囊水压大于内胶囊，从而使得内胶囊的管径缩小，而外胶囊挤占井中体积。当胶囊中水压与管道中水压差达到一个安全值时。就可以对需要检修的管道进行抽水，然后便可进行下井作业。
