Abstract

Purpose. One of the strategic objectives of Ukraine – the security of fuel and energy resources through the development of private oil and gas producing sector, as well as carrying out intensive activities for exploration of new deposits and revitalization of fields with declining production. To stabilize and increase oil and gas production, the use of new technologies in drilling is required. Improved methods of drilling and increase of the accuracy of well trunk laying are also necessary. The technological process of drilling is associated with the presence of errors caused by high temperature, high vibration and shock overloads, as well as the curvature of the wellbore. The use of means of determining the geometric characteristics of the well trunks with continuous monitoring of its trajectory allows to reduce errors. The parameters control of the spatial orientation of the wellbore is performed by means of information and measuring inclinometer systems. New designs and methods of data processing transducers for improved accuracy and reliability parameters, measured values, optimization of the technological process of drilling should be found. Methodology. The structure of inclinometer systems with the primary transducers based on magnetic fluids are obtained. Findings. Elaborated design of compact directional transducers based on magnetic fluid and nonmagnetic bead allows to minimize error and provide the required measurement accuracy under conditions of vibration and shock accelerations that occur during drilling. Originality. The approach to use displacement sensors with magnetic liquid creating an inhomogeneous magnetic field by means of a non-magnetic spherical element was proposed. Practical value. The proposed structures have high vibration strength, impact resistance and vibration resistance with small dimensions. The use of magnetic fluid in the inclinometer system will improve the accuracy of determining the trajectory of the wellbore, ensure the production of compact systems and reliability of operation.
