| Abstract. At present, in order to ensure accident-free operation of drilling rigs, advanced and expensive multifunctional systems of drilling monitoring and control are used. In spite of that a significant number of accidents take place and the probability of their occurrence to a certain extent depends on qualification of a driller, who, on the basis of his experience and also taking into account information from control systems, determines the current technical condition of the drilling string and beginning of possible accidents. Malfunctions are indirectly reflected in the wattmeter chart of the drill string motor. However, the information contained in the wattmeter charts, which reflects the technical condition of the drilling rigs and has a great diagnostic information potential, is not used in the control systems. Therefore, in order to exclude possible mistakes of a driller it is necessary to provide him with tools, allowing to facilitate his intuitive activity. In this regard, in order to ensure accident-free drilling process, it is proposed to create a signaling system to warn the driller about the beginning of a latent period of equipment malfunctions by analyzing the wattmeter chart with the use of possibilities of noise analysis technology and adaptive analogue-digital sampling. |
