Oil and gas well integrity monitoring and management system

Abstract

The invention provides an oil and gas well integrity monitoring and management system which comprises an on-site well integrity data monitoring device and a well integrity data processing and analyzing system connected to the Internet. The on-site well integrity data monitoring device monitors to obtain relevant data, through the well integrity data processing and analyzing system, the well fieldmonitoring data provided by the on-site well integrity data monitoring device is displayed, analyzed and fed in real time, well historical data is stored, inquired and analyzed, and the oil and gas leakage risk alarm is achieved based on analysis and judgment results. The visualization of the whole process of well integrity management can be achieved, an integrity file of each oil and gas well isformed, the risk of oil and gas leakage can be proactively identified, the oil and gas well safety risk warning is dynamically carried out in real time, and high pressure can be automatically releasedespecially for an sustained casing pressure well.

Description

technical field [0001] The invention belongs to the technical field of oil and gas exploitation safety management and monitoring, and in particular relates to an oil and gas well integrity monitoring and management system. Background technique [0002] Integrity management of oil, gas and water wells refers to the use of various means throughout the life cycle to reduce the risk of loss of control of formation fluids and fluids in wells and meet the requirements for safe production of wells. Mainly based on the well barrier, through the use of technology, management and other means to ensure the physical properties of the well barrier to realize the control of the fluid in the well and ensure the integrity of the well. [0003] Oil, gas and water wells will have different degrees of safety hazards in the production, operation and maintenance process. According to relevant statistics, more than half of the workover and well intervention activities are to solve the problems re...

Problems solved by technology

[0004] Carrying out the integrity management of oil, gas and water wells involves the integration and analysis of all aspects of well-related data. It not only needs to collect and organize data related to wells from different departments, but also needs historical data in different periods. According to the traditional management model, this is a This is a heavy task that requires cross-departmental and multi-professional collaboration. It takes a lot of time and energy, and the quality and requirements of data analysis cannot be guaranteed. This model often makes it difficult to deal with hidden safety hazards in oil, gas and water wells in the later stage, and the treatment costs increase and the treatment effect is poor. Unsatisfactory, seriously affecting the safe production of oil, gas and water wells
