INSTALLATION FOR EXTRACTING NON-GASIFIED LIQUID

摘要

An installation for extracting non-gasified liquid is used during operation in a raised pressure gas medium for raising liquid from oil wells. The installation for extracting non-gasified liquid is constructed on the basis of pneumatic well-drilling substitute pumps having working chambers alternately connected to a high-pressure source in the form of a compressor and to an exhaust gas pipeline which is connected to the atmosphere. Each pump is additionally provided with a central pipe for removing the exhaust gas, which pipe is an integral part of a through pipeline for removing gas, which pipeline is connected to a supporting connecting pipe which is located on a supporting flange and has an output to the atmosphere. The supporting flange is equipped with a compressed-gas-supply connecting pipe which is connected to the output of the compressor. The extracted liquid pipeline is in composite form and comprises a receiving part, pump working chambers, an intermediate part and an extracted liquid connecting pipe which is connected to a trunk pipeline which is arranged on a supporting flange mounted hermetically on the flange of a drive pipe. This provides for the raising of non-gasified liquid having an increased content of mechanical impurities during multi-stage raising of the liquid.
