BOREHOLE MEASUREMENTS TO BE TAKEN DURING WELL OPERATIONS OTHER THAN DRILLING Russian patent published in 2007 - IPC E21B44/00 E21B31/00 

FIELD: oil production, particularly to determine well conditions and operation parameters of fishing or other tools used for well bore freeing of foreign objects and to perform deep and/or inclined well operations other than drilling.

SUBSTANCE: method involves forming tool string with the use of drill tube sections, wherein tool string includes working tool and measuring instrument adapted to measure operation regime parameter and the working tool is fishing tool, anchor, pipe cutter, packer, well bore reamer, as well as milling or drilling-off tool; inserting tool string in well; activating working tool to perform well operation other than drilling; measuring at least one well operation regime parameter during said operation performing. Said well operation is fishing, lifting, well bore reaming, casing pipe cutting and so on. Measuring instrument measures torque, extension and compression force, rotation direction and frequency, which characterize above operations. The obtained information is used to control working tool.

EFFECT: increased well operation efficiency due to possibility to obtain information concerning well operations other than drilling.
