Objective Internal corrosion data governance is an important prerequisite for realizing the digital transformation of corrosion control and management business. At present, under the background of different sources of corrosion data, inconsistent data storage formats, and abnormal data, internal corrosion data governance is introduced which can efficiently solve the problems of disconnection between corrosion business management and data management, low standardization of data and difficult control of data quality.

Methods This paper explored and analysed the current situation of internal corrosion data collection and management, the data governance process, and the data governance effectiveness in the surface gathering and transportation system of PetroChina Southwest Oil & Gasfield Company (hereinafter referred to as Southwest Oil & Gasfield), and combine the corrosion data and control management platform of Southwest Oil & Gasfield to show the storage situation of the internal corrosion data in the key blocks.

Results (1) Through the formulation of internal corrosion data standards and management methods, the data entry format is standardized, the data sharing capability is improved, the data communication costs are reduced, and the timely, accurate, complete and standardized entry of various types of data is ensured; (2) abnormal data identification research is carried out on the internal corrosion data through the box diagram, and the identification accuracy rate reaches 88.3%, which realizes the efficient calibration of the internal corrosion data quality and improves the credibility of the corrosion data analysis and evaluation results; (3) based on the study of internal corrosion data entry, the data entry of 205 field stations and 233 pipelines was completed in 2022, it is helpful to fully display the corrosion situation of gas stations and pipelines in Southwest Oil & Gasfield; (4) based on the internal corrosion data after the treatment, the decision-making support research of corrosion data is carried out around corrosion prediction, risk assessment and overall pipeline corrosion control, and the effective utilization rate of data is improved.

Conclusions The continuous promotion of internal corrosion data governance can support the digital transformation of corrosion control and management business in Southwest Oil & Gasfield, and lay a solid foundation for the construction of a digital integrated collaborative model of the entire business chain of Southwest Oil & Gasfield.
