Abstract RU 2771354 C1

FIELD: oil and gas industry.

SUBSTANCE: invention relates to the oil and gas industry, in particular to a construction of a multi-hole gas well. The construction of a multi-hole gas well contains main and at least one side trunks, while the main trunk is fixed by technical columns, a production column and a shank. The lower end of the production column is installed obliquely directly above a roof of a productive reservoir, and joints of main and at least one side trunks are placed above a sole of the productive reservoir. Moreover, main and at least one side trunks behind joints are made with the lifting of faces to the roof of the productive reservoir. The shank contains a section of solid pipes located in a descending part of the main trunk from the end of the production column to the junction with the side trunk, and then, a section of filter pipes to the bottom of the main trunk located at the roof of the reservoir.

EFFECT: increase in the reliability of a construction of a multi-hole gas well for efficient production.
