© MYRONTSOV, M.L., 2018 Introduction. The research aims at the creation of electrometry equipment capable of solving the actual problems of geophysical exploration of oil and gas wells. Problem Statement. The existing equipment in Ukraine is not capable of reliably solving the problems of geophysical exploration of oil and gas wells in the conditions of Dnieper-Donets Basin. Purpose. Creation and well testing of appropriate equipment with a high spatial resolution. Materials and Methods. Combining potential probes that enable to restore the electric potential along the borehole axis and to solve the inverse problem with a high spatial resolution, a multi-probe resistivity logging tool has been created. Using the frequency scanning method, a multi-probe induction logging tool has been created. Results. Well tests of the developed equipment in the conditions of a terrigenous cut have been carried out and its efficiency has been compared with the existing equipment in Ukraine. Conclusion. The developed resistivity logging equipment has a higher resolution than LLS+LL+IL, it is also easier to operate, since it is configured as one device, instead of three separate ones. The developed induction logging equipment has the same vertical spatial resolution as the Il probe, but enables to define the geoelectric parameters of reservoir layers without involving other research methods.
