FIELD: oil and gas industry.SUBSTANCE: reservoir pressure maintenance system includes a water supply source, pumps, low-pressure water lines connecting the pump of the water supply source to booster pumps of injectors, which wellheads are equipped with shut-off and regulating valves. At that the low-pressure water lines are under maximum permissible pressure that exceeds the maximum permissible pressure at the input of the respective booster pump; the lines are equipped with pressure regulators. These pressure regulators ensure reduction of pressure at the input of the respective booster pump in the operation process up to a value lower that the maximum permissible pressure but not lower that the minimum permissible pressure for this pump. The pressure regulators are operating as downstream pressure controllers during limitation of the injection volume to one or several injectors or during their complete shut-down. The booster pump is designed for the input pressure as per the following formula.EFFECT: improved reliability of the pumps operation and increase of their life between overhauls.1 tbl, 1 dwg |
