The No. L Oilfield is an old oil field that has been developed for many years. With the advent of the era of artificial intelligence, the company has carried out the technical transformation, innovation, and upgrading of the No. L Oilfield to meet the change of comprehensive informatization, comprehensively upgraded the engineering design software, eliminated the original two-dimensional design, and fully adopted BIM design. The company relies on the building information model to meet the architectural design tasks in the existing oil region. The BIM model contains much more information than the 2D CAD plane, including complete information such as equipment name, structure type, construction process, cost, human resources, machinery, etc., which makes the architectural design tasks completed through BIM software more information-based and intelligent, so as better to serve the future oilfield industry upgrading and construction. Although the current BIM-related design and software are still new and have many shortcomings, with the development of technology and the continuous improvement of software, the building information model will play a decisive role in the future intelligent information age for oil field construction.
