FIELD: oil-and-gas production.
SUBSTANCE: invention related to boring with downhole hammer of underground stratum. Particularly, the invention related to measurement of forces applied to boring equipment during boring process. Method includes determination of contactless sensor electrical characteristics, located in borehole equipment, via applying load to borehole equipment and load value determination based on difference between of contactless sensor electrical characteristics when elongator is loaded and unloaded, at that contactless sensor electrical characteristic changes due first and second elements position change because of loading or distance between first and second elements, and change compensation, at least temperature or pressure using measurement results from the second sensor, located in borehole equipment.
EFFECT: avoiding interferences, strengthening of receiving strains, easier measurements and allow avoiding hydrostatic pressure influence on the measurement results.
