Research on multi-dimensional analysis model of drilling operations safety evaluation system

Abstract

Oil and gas drilling operation has the characteristics of large investment and high risk, so the effective identification and analysis of potential accidents is an important problem that needs to be solved urgently. In order to meet the requirements of complex analysis of drilling safety evaluation system, a multidimensional data analysis model based on data warehouse is constructed in view of the shortcomings of traditional database technology in information analysis ability, which transforms the application-oriented data structure into the analysis of multi-dimensional data structure, and provides a good environment and analysis method for drilling safety analysis and evaluation. According to the human, material, environmental and management factors of oil and gas drilling accidents, the relevant modelling topics were determined, and a multidimensional data model for analysing the potential accidents was constructed. This paper introduces the construction method of multidimensional data model with the theme of “analysis of potential accidents of drilling operation” as an example.
