Research and Application of Gas Well Condition Diagnosis and Remote Measurement and Control Technology

At present, 229 gas Wells have been put into production in X gas field, which has entered the middle and late stage of development successively. The demand for various measures reaches 8000 Wells per year. Well locations are scattered and management is difficult. By establishing an intelligent decision-making platform for gas Wells, efficient integration of dynamic and static data resources for gas field development, establishment of multi-data source comprehensive working condition diagnosis algorithm model, three-dimensional analysis of reservoir-wellbore-surface working conditions, comprehensive perception of gas well production dynamics, “manual analysis “into” intelligent decision-making”. The intelligent parameter adjustment algorithm model is established to form the remote measurement and control technology, so as to realize the status monitoring and remote dosing of gas well automatic dosing device, changing “traditional dosing “into” intelligent bubble row”. It is expected to form an intelligent demonstration area for the number of Wells in X gas field, with a total economic benefit of more than 9.3 million yuan and a cumulative gas increase of 5 million square meters. The research results can realize the comprehensive fine analysis and decision-making of gas Wells in Daqing oilfield and the key monitoring of measure Wells, improve the analysis and decision-making level of gas production technology, and help the gas field to leap from digitalization to intellectualization, which has a wide range of application prospects.
