One of the main problems in the operation of wells, in field practice, is the occurrence of annular pressures in the cemented annular space and behind-the-casing flows. In this connection, a number of complications arise that lead to depressurization of wellhead equipment, the formation of griffins, interfacial flows and technogenic deposits. Timely high-precision diagnostics of geological and technical causes and sources of occurrence of annular pressures in wells of any purpose and category will prevent the occurrence of such complications. Despite the urgency of this problem, until now there are no universal methods for studying multicomponent annular space fluids for diagnosing the source of annular pressure in wells. The article analyzes the modern methods and methods for diagnosing annular pressures and power flows, which at an early stage prevent the consequences caused by the leakage of the annular and annular space of production wells in oil and gas fields.
