Abstract: Progress in information technology, such as IOT, cloud computing and large data, plays a great role in construction of digital oilfield. Inclusion of exploration and development data into assets management becomes an important production element of oil and gas enterprises while application of large data is an important way for search of oil and gas resources, optimization of production and improvement of decision-making efficiency. The surface optimized and simplified work is represented by “Gangxi Pattern.”Namely, construction of surface engineering standardization is integrated into oil and gas production IOT system represented by digitalization of oil and water wells, digitalization of pipelines and digitalization of stations and storage depots. Those measures fully improve surface engineering construction of old oilfields, exerting enormous effects on conversion of production mode, optimization of labor organization, improvement of productivity and reduction of safety risks. With cloud computing conception adopted and harmonious research cloud of exploration and development established, application service with integration of hardware, software, project data and management of achievement is provided for researchers to help their research work of seismic interpretation, geological modeling and numerical simulation. The efforts are made for construction of digital oilfields focusing on optimization of cloud computing pattern, popularization of IOT technology and study of large data analyzing technology. Those measures are aimed at promoting development of intelligent oilfields and improving creativeness of integrated exploration and development, on-the-site intelligent controlling capacity of oil and gas production and production business analyzing and decision-making capacity, laying a solid foundation for the company’s sustainable development.
