FIELD: drilling of soil or rock.
SUBSTANCE: invention relates to telemetry means in a well and can be used to eliminate interference caused by the operation of the drilling pump. In particular, a method is proposed for filtering interference caused by the operation of a drilling pump, with hydropulse telemetry, including the following: reception of the output signal of the pump stroke sensor; selection of the adaptation coefficient in the adaptive filter module; correction of the adaptation coefficient when the adaptive filter module achieves convergence; reception of the sensor input signal; the output of the filtered signal; and changing the configuration of the drilling tool based on the output signal.
EFFECT: apparatus for implementing said method is also disclosed.
