Features of the development of a search system for technological objects of oil pipeline transport

Abstract

The study investigated the structure and operating principle of a search device designed for intra-pipe technological objects used in oil pipeline transportation. Precise detection of the position of intra-pipe devices on the Earth's surface above an underground oil pipeline allows performing technological operations with minimal costs. The solution to the problem of developing a direction-finding device based on the sum-difference method for determining the location of an in-line technological object using a system of magnetic antennas (locators) located in the ground-based unit and a magnetic transmitter installed in the in-line device is considered. A computational experiment was conducted, as well as modelling, assembly, and testing of the search device. Parameters for optimal positioning of locators were determined to solve the task of finding the distance to the point in the pipeline where the in-line technological object is located.
