METHOD OF DELIVERY OF GEOPHYSICAL DEVICES INTO HORIZONTAL WELLS

摘要

FIELD: drilling of deep intensively inclined oil wells. SUBSTANCE: geophysical device is run into well. It is mechanically connected to lower end of the first pipe and electrically connected with lower end of cable length. All pipes of set are successively lowered and connected alternately with one another mechanically and electrically. Upon completion of lowering of all pipes, connected mechanically and electrically to upper end of last pipe is logging cable with the aid of special cable lug. The whole system is lowered into well bore horizontal section and device delivered to interval of investigation. Information is registered in device hoisting. EFFECT: higher reliability, extended field of method application and higher accuracy in measurement of geophysical parameters. 2 dwg
