Abstract
Method fir initiation of inflow at well testing in process of drilling is in lowering to drill pipes of pump-compressor string, insulation of tested interval of well and fluid takeout through excitation of its inflow from bed. To prevent collapse of drill string at testing deep gas-saturated beds with gas discharge to surface, fluid takeout is carried out through pump-compressor pipes with simultaneous washing of well through channel in drill pipes.
