Field Geophysical Researches by Small-sized Borehole Equipment through Y-Tool Installation
The downhole logging by small-sized well equipment are carried out during the work of a well with the help of
an electrocentrifugal pump (ECP) equipped by by-pass system with possibility of running instruments in the process of
ECP's work.
Technical conditions of logging: A set of tubing together with ECP and a by-pass system is run-in. It allows to
register borehole geophysics data against perforated formations at free movements of an instrument through the interval
of pump's setting.
