A COMPLEX TOOL FOR WELL MONITORING

摘要

A complex tool according to the invention comprises a cylindrical housing, a lever centralizer aligning the tool along the well axis and having at least six levers and a fluid flow temperature sensor and inflow temperature indicator located on the tool axis. A fluid phase composition sensors are located on the centralizer levers and distributed along the well bore circumference. An additional fluid phase composition sensor is located on the tool axis. At least one additional fluid flow temperature sensor and at least one additional inflow temperature indicator disposed on each lever and distributed along the well bore circumference and located on the same line with the phase composition sensors parallel to the tool axis. There is an additional upper lever centralizer in the tail part.
