The capability of multisensor technology for carrying out of field research of horizontal gas and gas-oil wells is consi - dered. Filtration properties of reservoir and bottomhole zone, productive characteristics of the well, and also working hole sections, characteristic and the intensity of the inflow from the test intervals, the pressure loss along the length of the horizontal wellbore are determined. It is noted, that studies of gas-oil wells allowed to define a gas flow zones for their further isolation.
