SHALLOW GAS PRODUCTION DEVICE OF SHALLOW GAS FIELD

摘要

The present invention is to provide a device for controlling the risk factors caused by a sudden gas ejection or gas explosion between gas field production and a production test by blocking upper and lower portions of a reservoir section capable of producing natural gas at the drilling hole with a packer; and by removing only mud from the section and at the same time continuously circulating the mud from the section from the ground surface to the upper packer. To this end, a shallow gas production device of a shallow gas field, according to an embodiment of the present invention, is characterized by including a shallow gas production portion comprising: a main body portion of which the height is adjusted to correspond to the height of a reservoir positioned underground; a first packer connected to an upper portion of the main body portion; and a second packer connected to a lower portion of the main body portion.
