Abstract

Abstract: Real Time Operation Center (RTOC) based on Internet of Things is an expert collaboration platform integrating optimization of pre-drilling engineering plan, optimization of real-time construction and evaluation of post-drilling effects. Based on the requirements of risks control, cost reduction and efficiency enhancement for complex structured wells, RTOC has been rapidly developing with the help of technological achievements made in measurement while drilling, acquisition of information, network communications and application software. This paper analyzes the best practice and core elements of RTOC in foreign countries. Data are the basis of drilling remote support system operation. They also serve as the scientific decision-making basis for the system. Professional software holds the key to the services provided by the system. Expert team is the core of system operation. This paper introduces RTOC deployment and construction of CNPC. Engineering technological service and support is changing into remote expert consultation real-time decision-making support mode from the traditional support mode of expert’s frequent trips to well sites. The decision-making pattern for drilling service is also turning from individual experiences to combination of expert consultations and technological knowledge base. With rapid development of high-performance graphics workstations, Internet of Things, big data and cloud computing, RTOC is developing towards the “comprehensive perception, automatic operation, prediction of trends, and optimization of decision making”. Concretely, it functions in the form of submerged digitalized simulation, automatized drilling, online warning and diagnosis and geological engineering integration.
