FIELD: oil and gas industry.
SUBSTANCE: control device of drilling parameters during drilling of an underground formation includes a drilling element; at least one acoustic signal transfer and receiving sensor in a well; downhole control device and downhole electronic device. Electronic device is provided with a processor and memory. Acoustic signals are transferred and received in the well. Received acoustic signals are processed to obtain at least one characteristic including formation movability. Fluid parameters are determined on the basis of variation of at least one characteristic. Parameter determination results are given and the decision on the well arrangement is taken based on certain parameters.
EFFECT: improving deposit development efficiency.
