METHODS, SYSTEMS AND DEVICE FOR TEST ON FLEXIBLE TUBING STRING

摘要

FIELD: engines and pumps. ^ SUBSTANCE: method involves introduction of common flexible tubing string to the well bore with annular space formed around flexible tubing string; activation of the device for separation of zones for isolation at least of one well bore zone; direction of test fluid medium to well bore through flexible tubing string to location place above the aforesaid zone; removal of outlet fluid medium from isolated zone and test fluid medium from flexible tubing string through annular space; measurement of characteristic of flow rate and pressure of outlet fluid medium during discharge. ^ EFFECT: isolation and test of separate zones without removing operating tubing string. ^ 20 cl, 15 dwg
