摘    要:目的为有效控制气田水回注泄漏风险,将地下水污染环境风险防控关口前置。方法结合回注井日常运行参数,建立了回注井Hall曲线关系,利用回注井累积注入量与Hall积分(注入压差×累计时间)的线性关系,监测回注异常工况,并应用微地震监测技术进行结果验证。结果应用Hall曲线能更为简便直观地对回注井进行跟踪监测,消除单次注水参数变化等带来的影响,在气田水回注井地下水常规监测的基础上实现回注风险的提前预警,提高气田水回注井泄漏监测的准确性和科学性,为下一步回注井地下水环境风险预警奠定基础。结论气田水回注应进一步建立完善以气田水回注井完整性管理为核心的地下水环境风险防控体系。

关 键 词:Hall曲线  气田水回注  环境风险  地下水  微地震监测  防控措施

Abstract:ObjectiveIn order to effectively control the leakage risk of water reinjection in the gas field, the prevention and control gate of groundwater pollution risk is put in front. Methods This study established the Hall plot of the reinjection well combined with the daily operation parameters. The linear relationship between the cumulative injection volume of the reinjection well and Hall integral (injection pressure difference×cumulative time) was used to monitor abnormal reinjection conditions. The application of microseismic monitoring technology also verify the results. ResultsThe application of Hall plot can track and monitor the reinjection wells more easily and visually, eliminate the influence of changes in single injection parameters, realize the early warning of reinjection risk on the basis of routine monitoring on underground water in the water reinjection wells, improve the accuracy and scientificity of leakage monitoring on the reinjection wells in gas field, and lay a foundation for the early warning of underground water environmental risk in the reinjection wells in the following step. Conclusions The groundwater environmental risk prevention and control system with the integrity management of gas field water reinjection wells as the core should be further established and improved.
Keywords:Hall plot  gas field water reinjection  environmental risk  underground water  microseismic monitoring  prevention and control measures
