FIELD: oil and gas industry.
SUBSTANCE: invention refers to definition of geometry of boreholes inside cased wells by means of cross borehole electro-magnetic measurements. There is disclosed a method of definition of location of a receiver in a borehole of a well equipped with a conducting casing pipe, the said method consisting in electromagnetic field induction from the emitter in the first well, also consisting in detection of the first electromagnetic field induced by the emitter in the first location by means of at least one receiver placed in the second well having conductive casing pipe, in detection of the second electromagnetic field induced by the emitter in the second location by means of at least one receiver, and in calculation of set of coordinates of geometry for the first location on base of the first electro-magnetic field and the second electro-magnetic field. Also there is suggested the method of reflection of trajectory of a cased borehole of a well and the well system of logging measurements.
EFFECT: upgraded accuracy of definition of geometry of wells.
