Abstract

Purpose. Ukrainian Oil and Gas Industry today has a high demand for an increase in hydrocarbon production. There is a need to find new deposits, improved drilling techniques, recovery and improve the accuracy of laying the wellbore. Technological features of the drilling process associated with the presence of errors caused by the formation pressure and high temperature, high impact and vibration overload, as well as the curvature of the wellbore. To reduce errors caused by these factors, allows the use of means of determining the geometric characteristics of trunks with constant control of the well path. The primary means of managing and controlling directional and horizontal drilling of wells are directional information-measuring system. The search for new designs and methods of primary data converters such systems to improve the accuracy and reliability of the parameters, measured values, optimization of the drilling process, improve the quality of oil and gas production, reduce production costs.

Methodology. Received design inclinometer system Helmholtz coils and thin-film ferroprobes, which provides tightly fixed magnetic axis and eliminates interference caused by the windings of the solenoid type and increase accuracy. The simplicity, small size and versatile design provides a cylindrical frame with a profiled helical groove.

Findings. The dependence of the ratio of the flux gate size and diameter Helmholtz coils, allowing to minimize error and provide accurate measurements for the real problem with regard to the conditions of drilling. Resize ferroprobe (increasing or decreasing the length) without affecting the performance of the inverter allows the frame with spiral grooves. 

Originality. Improved information-measuring multishot survey system by using as primary transmitters of Helmholtz coils and thin-film ferroprobes who have no solenoid coil.

Practical value. The use of Helmholtz coils and thin-film ferroprobes in information-directional measurement systems will improve the accuracy of determining the parameters of the trajectory of the borehole, to ensure the production of small-sized systems.
