FIELD: soil or rock drilling; mining.
SUBSTANCE: group of inventions relates to borehole assembly and method of orientation of arrangement and actuation of pressure activated tools. Downhole assembly includes an orienting tool, which includes a functional unit, which receives measurement results of well parameters, and a pulse generating device which transmits measurement results of well parameters in order to orient the location of the downhole tool. Throttling device is connected to the tool orienting the tool and includes a nozzle limiting the flow of fluid medium through it, and at that the circulating valve is connected to the throttling device and includes a nozzle limiting flow of fluid medium through it. Lowering tool for the shank end is connected to the circulation valve in order to transport the shank end and pressure-activated tool into the well shaft. Pulse generating device operates with fluid at first pressure value, and throttle device is actuated by increasing pressure from first value to second value. Circulation valve is actuated by fluid medium at third pressure value, and pressure activated tool is actuated by increasing pressure from third value to fourth value.
EFFECT: technical result is enabling orientation of location and actuation of pressure activated tools.
