The Common 13Cr Steel RUL Forecast Model for Tri-High Gas Well Pipe

Abstract:

Common 13Cr steel is a kind of corrosion resisting material to be used as gas well pipe working under the situation of high pressure, high temperature and high H₂S, but it’s still destroyed in an undesirable period because of the poor working environment. To forecast its remaining useful life, parameters indicating the failure of gas well pipe with high pressure and high temperature and high H₂S are collected to form a dataset. The dataset is then transformed into fuzzy set and gas wells are classified according to it. Then the failure time forecast model of gas well pipe is established based on the well’s fuzzy set. Finally, 2 wells remaining life is calculated by the model. It is verified that the result got is in line with the actual situation. The model established is importantly meaningful for the safety production and the proper selection of gas well pipe.
