METHOD TO PERFORM SURVEY OF WELL PROVIDED WITH SUCKER-ROD PUMP Russian patent published in 2006 - IPC E21B47/00 E21B47/01 

FIELD: oil industry, particularly to perform running wells provided with flow strings and sucker-rod pumps.

SUBSTANCE: method involves stopping rocker-machine operation during work performing at well head and sucker-rod pump operation for not more than 20 min; lowering instrument into well; lowering instrument connected to logging cable through cable head for 2 meters; bringing rocker-machine in operation and continuing instrument lowering in well; repeatedly brining sucker-rod pump in operation up to working level reaching during instrument lowering and after instrument lowering; performing survey during sucker-rod pump operation when sucker-rod pump reaches working mode of operation; lifting the instrument to well head after survey termination; stopping the tool at height spaced 100 meters from well head; bringing rocker-machine and sucker-rod pump out of operation; removing the instrument from well and repeatedly bringing rocker-machine and sucker-rod pump in operation.

EFFECT: increased operational reliability due to prevention of logging cable loop forming about flow string and increased reliability of survey results due to measurement performing in working well operation regime.
