FIELD: mining. ^ SUBSTANCE: electric immersed pump installation is placed in well; electric current is fed to pump installation and borehole fluid is produced. In specified time intervals oscillating frequency of rotation of the pump installation is changed in a chosen range, owing to which seismic waves with alternate frequencies are transmitted to the formation. Additionally, a layout of testing can include two pump installations within the scope of the disclosed here invention, also the seismic sensor is arranged together with the second pump installation. ^ EFFECT: ensuring seismic investigations without additional equipment. ^ 17 cl, 2 dwg |
