Abstract

At present, inhibitors are widely used in the gathering and transportation pipelines of oil and gas fields. However, existing methods for predicting pipeline inhibition efficiency and conducting risk assessments cannot be promptly carried out on-site.This paper focuses on oil, gas, and multiphase pipelines. Through multiphase flow (MPF) simulation and evaluation experiment of inhibition efficiency, a complete data sample of the influencing factors of inhibition efficiency is formed. Grey relational analysis and principal component analysis (GCA) are combined to determine the main controlling factors of inhibition efficiency. Based on the Frequent Pattern Tree (FPT) algorithm, which is used to mine association rules, a prediction model for inhibition efficiency is established. Finally, a corrosion failure risk assessment (FRA) matrix based on inhibition efficiency is proposed.The results show that multiphase flow simulation can yield 16 accurate flow - parameter results, with a relative error of less than 5 %. The relative error between the inhibition efficiency of 12 experimental groups and that on-site is no more than 12.37 %. Moreover, the inhibition efficiency of TL201 is the highest. The concentration of inhibitor significantly affects the inhibition efficiency of the three types of pipelines. Additionally, flow parameters related to the liquid also have a substantial impact on inhibition efficiency.Based on the data samples containing 3086 mined data points, A total of 3247 association rules for oil, gas, and multiphase pipelines were obtained, and the relative error of the model is ≤ 14.29 %. Meanwhile, the optimal operating conditions for the three types of pipelines are proposed. In accordance with API RP 581–2016, a corrosion failure risk matrix for gathering and transportation pipelines, with inhibition efficiency as the evaluation index, is established. When the proposed method is applied to specific oil, gas, and multiphase pipelines in the TL and ZG oilfields, the application results indicate that this method has good adaptability for oil, gas, and multiphase pipelines.

期刊介绍： The Process Safety and Environmental Protection (PSEP) journal is a leading international publication that focuses on the publication of high-quality, original research papers in the field of engineering, specifically those related to the safety of industrial processes and environmental protection. The journal encourages submissions that present new developments in safety and environmental aspects, particularly those that show how research findings can be applied in process engineering design and practice. PSEP is particularly interested in research that brings fresh perspectives to established engineering principles, identifies unsolved problems, or suggests directions for future research. The journal also values contributions that push the boundaries of traditional engineering and welcomes multidisciplinary papers. PSEP's articles are abstracted and indexed by a range of databases and services, which helps to ensure that the journal's research is accessible and recognized in the academic and professional communities. These databases include ANTE, Chemical Abstracts, Chemical Hazards in Industry, Current Contents, Elsevier Engineering Information database, Pascal Francis, Web of Science, Scopus, Engineering Information Database EnCompass LIT (Elsevier), and INSPEC. This wide coverage facilitates the dissemination of the journal's content to a global audience interested in process safety and environmental engineering.
