DEVICE WITH BLOCK AND TACKLE TO DISPLACE DOWNHOLE INSTRUMENTS UNDER PRODUCTION PUMP

摘要

FIELD: oil-and-gas industry.SUBSTANCE: proposed device is configured as follows. Electric drive is arranged under extraction pump and connected via bevel gear pair and chain gearing with bottom moving block and tackle running on the principle of high-speed transmission. Multiple-strand geophysical cable extends from well mouth supply said electric drive and is wound on top and bottom tackle blocks Downhole instruments controlled remotely from well mouth via geophysical cable are suspended from its end under bottom moving tackle block. Device case is equipped with top and bottom end switches to reverse the electric motor drive.EFFECT: increased interval of analysis over well depth, transmission of data in real time, decreased device OD.1 dwg
