The development of theoretical foundations for electromagnetic flaw detection of oil and gas wells

Magnetic and Electromagnetic Methods


Theoretical foundations of the development of nonstationary electromagnetic (EM) flaw detection of wells as applied to the problem of measuring the wall thickness of casing and lifting pipes of oil and oil-and-gas wells are considered taking into account the diversity of EM properties of metals. Analytical dependences and experimental data on measuring the EM fields formed in the presence of local inhomogeneities of a string, such as small-diameter holes, are analyzed. Main requirements for the engineering parameters of the equipment and principles of interpreting well-logging EM flaw detection are shown.
