METHOD OF GAS WELL COMPLETION |
摘要 |
FIELD: mining.SUBSTANCE: in process of drilling in the area of impervious roof above the productive formation an extended annular chamber is created, which communicates with the intra-column space through openings of the special casing coupling. The chamber and the intra-column space are filled with hydro-sealing liquid which creates a constant excess of the hydrostatic pressure of the liquid column above the formation pressure of the gas.EFFECT: improvement of efficiency and quality of creation of gas wells, the safety of their operation due to creation of reliable, more quality and permanently working hydro-sealing preventing the migration of gas through the borehole annulus.4 dwg |
