苏里格气田数字化排水采气系统研究与应用 摘 要:苏里格气田气井普遍具有低压、低产、小水量的特点，单井产量低，携液能力差，部分气井井筒存在积液甚至出现水淹停产。为了确保气田平稳生产，在低压低产气井实施了多项排水采气措施，取得相应效果。随着气田开发时间增长，积液井不断增多，排水采气方面的工作量不断增大，如沿用以前传统的人工对气井的积液判识和手工编制措施方案的做法难以满足气田发展需要。苏里格气田以数字化管理为目标,数字化气井、数字化集气站、数字化作业区、数字化采气厂的建立，开发 数字化排水采气系统集成气田数字化技术和采气工艺技术，利用计算机对气井进行积液判识,自动生成制措施方案，创新排水采气工作模式,实现自动排查气田产水井、提示积液井、计算井筒积液量、优选气井排水采气措施、实时跟踪气井生产情况、分析总结排水采气措施效果等功能。通过该系统，量化排水采气措施关键参数，减轻技术人员工作量，提高技术人员工作效率，改善气田现场技术支撑环境。 关键词：数字化 排水采气 井筒积液 措施 跟踪分析 Research and application of a digitalized drainage gas recovery system in the Sulige Gas Field Abstract: Characteristics of the Surig gas field has generally low, low, small volume, low single well production, liquid carrying ability is poor, part of wellbore fluid and water flooded. In order to ensure smooth production in gas field, low pressure and low yield gas well implemented a number of drainage gas recovery steps, to obtain the corresponding effect. With the development of gas field development time growth, effusion wells increasing, the drainage gas recovery workload increases, such as to use the previous work is difficult to satisfy the gas field development. Digital drainage gas recovery system integration of digital gas field and gas recovery technology, optimization of the core technology, gas drainage pattern mining innovation, realize the automatic checking gas field wells, wells show effusion, calculation of wellbore fluid, preferably of drainage gas recovery measures, real-time tracking of gas well production, analysis and summary of drainage gas recovery measures etc.. Through this system, the key parameters of gas drainage measures to quantify, reduce technical staff workload, improve work efficiency and technical personnel, improve the supporting environment gas field.
