On Inclinometric Systems Hardware Complexing

The paper considers the issues of the inclinometric systems complexing, based on a three-component fluxgate azimuth sensor and a three-component zenith angle sensor in the tasks of determining the spatial orientation parameters of wells and borehole objects. The structure of the inclinometric system, the measuring angular parameters, indicators affecting the accuracy of the measurements, the factors of additional measurement errors occurrence are considered. While the inclinometric system is moving inside an open-hole well, it is systematically exposed to various disturbing factors, which include shock overloads, high temperatures, magnetic anomalies, etc. An approach to constructing the integrated inclinometric systems, based on the same type of downhole tools, is discussed to reduce the influence of these factors on the measured information of the device and to reduce the total error of the spatial orientation parameters measurement at the oil and gas wells. The method of checking the inclinometric system operability in the field near the well and its main criteria are studied.
