METHOD OF ADAPTING A DOWNHOLE MULTI-PHASE TWIN SCREW PUMP FOR USE IN WELLS HAVING A HIGH GAS CONTENT AND A DOWNHOLE MULTI-PHASE TWIN SCREW PUMP

摘要

A method of adapting a downhole multi-phase twin screwpump for use in wells having a high gas content. A first stepinvolves positioning a supplementary liquid channel in ahousing of the pump in fluid communication with a pumping screwnear an intake end of the pump. A second step involves feedingsupplementary liquid through the supplementary liquid channelto the pumping screw, thereby enhancing a liquid seal aroundthe pumping screw.
