Problems solved by technology

[0003] In the field of gas mining, some of the currently used hole sealers have poor antistatic ability when used, and the sealing effect is not good, so that the normal mining of gas cannot be guaranteed to the greatest extent, and there is a certain risk in use. The structure of the hole sealer is more complicated when used, the assembly process is more, the cost of assembly and use is high, and it is not easy to popularize. Therefore, a new two-block one-shot hole sealer is proposed to solve the above problems.

Abstract

The invention relates to the technical field of gas production, in particular to a novel double-plugging one-injection hole packer. The novel double-plugging one-injection hole packer comprises a gaspipe and a grouting pipe. A hole packer core is arranged on the outer side of the gas pipe, and the hole packer core and the gas pipe are in sliding connection. An expansion rubber pipe is arranged onthe outer side of the hole packer core, and the hole packer core is fixedly connected with the expansion rubber pipe. According to the novel double-plugging one-injection hole packer, by arranging the hole packer core, the arrangement cooperates with communication of the hole packer core and the gas pipe, communication of the hole packer core and the grouting pipe, fixed connection of the expansion rubber pipe and a telescopic iron sheet and fixed connection of the expansion rubber pipe and the grouting pipe, a grouting pipeline is located in the expansion rubber pipe, a gas drawing pipelineis located in the rubber pipe, and when the device is used for producing gas, the device can be fast assembled; operation is easy and convenient, and time and labor are saved during operation; and theassembling and use cost of the device is greatly reduced, and popularization and use are easy.

Description

technical field [0001] The invention relates to the technical field of gas mining, in particular to a new two-blocking-one-injection hole sealing device. Background technique [0002] Gas is a colorless and odorless gas formed at the initial stage of coal accumulation by plants. When coal is formed, due to physical and chemical effects in high-temperature and high-pressure environments, the cellulose and organic matter of plant species generate gas. The gas needs to be extracted from the coal seam. When extracting the gas, it is necessary to drill holes in the coal seam first, and then extend the gas pipe into the drilled hole to extract the gas. This requires the gap between the drill hole and the gas pipe to be sealed for a certain distance with cement. Due to the complex structure of the coal seam and many cracks, coal mines generally require a sealing distance of 12 meters. The distance of 12 meters from the orifice to the hole requires cement to seal the 12 meters. When...
