gas pipeline

The article deals with the existing system of gas pipelines between hydrocarbon production facilities at the Yuliivskyi oil and gas condensate production facility (YOGCPF). This system of gas pipelines ensures the flow of hydrocarbon raw materials from the wells of Narizhnianske, Yuliivske and Skvortsivske oil and gas condensate fields to the complex gas treatment unit (CGTU). The preliminary treatment of natural gas from mechanical impurities, liquid, hydrocarbon condensate and water is carried out at gas preparation plants of these fields.

We consider the analysis results of the stress strain state of main gas pipeline underground section. During the analysis we take into account soil compliance in areas, where the pipe goes out on the surface. The estimated model is adopted as a triple section beam with pinched ends, which extreme areas are based on the elastic foundation of Winkler type. Calculation algorithm is constructed using the matrix method of initial parameters. In the calculation example, we illustrate the impact of the soil compliance on pipe deformation as well as on bending moments in its cross section
