Assessment of the degree of environmental pollution in emergency situations on main oil pipelines

Abstract

The methodology for calculating the throughput and operating parameters of the main oil pipelines has been improved, taking into account small oil leaks. Regularities of the change in oil pressure at the beginning and end of each of the sections of the pipeline, the volumetric flow rate of liquid in the pipeline from the linear dimensions of the through holes and their location on the pipeline route have been identified, and the corresponding mathematical models have been developed. The degree of environmental pollution during oil infiltration into the soil is estimated taking into account the physical properties of oil, the profile of the pipeline route, the volumetric productivity through the hole and the duration of the oil leak.
