FIELD: oil and gas production.
SUBSTANCE: invention refers to oil industry, particularly to collection of gas-liquid production and to preparing water for system of maintaining reservoir pressure (SMRP) at cluster of wells. Installation consists of operating wells communicated with a unit for oil separation and dehydration by means of pipeline, of an oil-gathering collector and of water conduits of the system for maintaining reservoir pressure. Additionally, the installation consists of a pit-well for after-purification of produced water. The installation can additionally include a purification unit of produced water and operational and pressure wells of several of neighbour clusters for simultaneous maintenance of the said clusters.
EFFECT: increased efficiency of operation of complex cluster installation for dehydration of oil and for purification and utilisation of produced water due to prevention of mixing water from different sources, and, correspondingly, elimination of salt deposition; reduced metal consumption of system for oil collection and maintenance of reservoir pressure, reduced power expenditures due to avoiding use of powerful pump aggregates.
