DOWNHOLE ARRANGEMENT OF OPTICAL FIBRE FOR SEISMIC EXPLORATIONS Russian patent published in 2017 - IPC G01V1/40 G01V1/22 E21B47/14 

FIELD: geophysics.

SUBSTANCE: invention relates to geophysics and can be used during seismic explorations. Proposed is a downhole arrangement of optical fibre for seismic explorations. Embodiments of this invention may include methods of arranging a sensor distributed over the reeled optical fibre in the well, integrated in the ballast or the load for a seismic optical probe for arrangement of a light single-use fibre-optic cable opposite to well walls by means of gravity. Method may also include a sensor distributed over the unreeled optical fibre and the use of the optical fibre as a distributed seismic receiver. After the fibre-optic distributed sensor arrangement according to the methods of the present invention data can be received and processed by different methods.

EFFECT: technical result is higher information value of measurements with simultaneous simplification of the research process.
