WELL OPERATION METHOD Russian patent published in 2004 - IPC

FIELD: gas industry, in particular, method used in wells operated only with the use of gusher column or in wells using both gusher column and pipeline interspace.

SUBSTANCE: method involves withdrawing gas from well; determining with the use of measuring instrument parameters of gas flow in pipeline of gas-collecting ground system; comparing resultant data with predetermined parameter values and controlling production rate depending on ratio of obtained and predetermined parameter values. Method is characterized in that before determining of gas flow parameters, gas is preliminarily dried by directing it through process aperture in pipeline of gas-collecting ground system first into heat-insulated branch pipe mounted on said pipeline, and further into heat-insulated ascending offset and into descending offset communicated with atmospheric air or artificially cooled air; directing condensed liquid into pipeline of gas-collecting ground system through process aperture in pipeline, and supplying dried gas from descending offset to measuring instrument through ascending offset.

EFFECT: enhanced reliability and increased efficiency of method.
