Abstract: Technique of auto-discharge and auto-metering for separator waste water has been used widely in da tian chi gas field.The paper give a brief introduction to the basic principle and the achieve process.In using, some particular problems can not be overlooked.Such as, electrical discharge valve movement influence waste auto-discharge, waste water metering beginning and production techneque request contradiction, translator for fluid liquid level accuracy influence to waste water metering, pipeline jam by hydrate frozen and the procedure for solving the jam, some optimum measurements have been taken to slove those problems.Those measurement expand this technique using situation.
