FIELD: oil producing industry. ^ SUBSTANCE: invention relates to drilling, completion and operation of oil and gas wells. Proposed device includes displacement type hydraulic supercharger consisting of row of sections, compression chambers communicating with supercharger, each containing suction valve to deliver gas or gas-liquid mixture from independent source into chamber. Delivery valve communicating with consumer is arranged over suction valve. Pump to deliver feed liquid through suction valve of supercharger is installed to form hydraulic seal in compression chamber. Compression chambers are made in form of separate compression module connected by pipelines with hydraulic part of supercharger. Outer diameter of compression chamber (dch.out is found from expression where dw is thickness of chamber wall; ds is diameter of supercharger; n is speed of supercharger shaft, min-1; r is supercharger half travel; where L is length of connecting rod; g is free fall acceleration. Diameter of pipeline (dpl) connecting compression chamber with hydraulic part of supercharger complies to the following equation: where alpha is angle between axis of pipeline and vertical. Capacity of said pipeline (Vpl) complies with relative Vpl<tausat.n.bl-Vs where tausat is time of saturation of liquid with gas at working pressures; where Ql is flow rate of liquid; Vs is volume described by supercharger. ^ EFFECT: increased capacity, improved repairability. ^ 4 cl, 1 dwg |
