A method of preserving gas and gas condensate wells with high permeability formation productivity in conditions of abnormally low reservoir pressure

摘要

Method of preserving gas and gas condensate wells with high permeability of the producing formation in conditions of abnormally low reservoir pressures, comprising a filling fluid of the borehole, characterized in that the barrel and gas condensate wells through the christmas tree is filled with liquid mixture with a filler closed valve christmas tree and leave gas and condensate wells under pressure, wherein the density of the liquid and the filler are equal, and the volume of the mixture is determined by the equation: V = π · D · (h + h) / 4, where V- volume fluid admixture with filler m; D- inner diameter of the production casing, m; h- interval perforations, m; h- depth slaughtering, m, and applied as a liquid inert non-freezing liquid, such as water or methanol vodospirtovye other solutions, as in filler - e.g., aluminosilicate microspheres or microspheres made from a different material.
