Analysis of the causes of non-sealing and failures of pump-compressor pipes in oil and gas wells

Abstract

Pump-Compressor Pipes (PCP) are designed to ensure the operation of the well: transporting oil and gas within the casing column, for repair and hoisting operations. Damage to PCP can lead to the well's failure, so the topic of detection, prevention, and avoidance of accidents remains relevant. The non-sealing of pump-compressor pipes (PCP) may be associated with violations of manufacturing standards for the pipes themselves or their components.Transducers, fittings for mounting column wraps, connecting devices during the descent of column sections, two-stage cementing sleeve couplings, check valves, and other elements should have strength indicators not less than the strength of the pipes themselves.
