METHOD OF COLLECTION AND PREPARATION OF GAS-CONDENSATE MIXTURE FOR TRANSFER IN DEVELOPMENT OF GAS-CONDENSATE FIELDS AT HIGH FORMATION PRESSURE (VERSIONS) Russian patent published in 2001 - IPC

FIELD: gas production industry; development of fields at deep bedding of productive strata. SUBSTANCE: stratum product from wellhead is fed to throttling device. Then, paraffin and/or hydrate inhibitor is introduced in stratum product which is directed to intermediate gathering station through surface or under-surface heat- insulated line where stratum product is subjected to stepped separation performed for separation of liquid and gaseous phases at simultaneous cooling of product being separated in recuperative heat exchanger. Liquid condensate is discharge to condensate stabilization unit after separation. Additional throttling is effected in sections feeding the gas-condensate mixture being separated between separators of separation system. EFFECT: reduced paraffin and hydrate formation on surfaces of equipment; enhanced operational reliability increased yield of separated products; improved quality of cleaning gas-condensate mixtures. 17 cl, 2 dwg
