磨溪气田开发对区域水环境影响的评估

EVALUATING THE INFLUENCE OF MOXI GAS FIELD DEVELOPMENT ON REGIONAL WATER ENVIRONMENT

磨溪气田属我国较大的整装气田，投入开发以来气田对探区环境的水质、大气、土壤、植被有何影响是环保工作人员应关注的问题。通过对涪江断面及九道坎水库几年的跟踪监测，详细分析了气田勘探开发及天然气加工处理产生的钻井废水、井下作业废液、气田水、炼化废水对区域水环境的影响程度，得出了区域内主要河流涪江及九道坎水库的环境贡献值，从而为进一步开发磨溪气田提供了环境管理的依据。

oxi gas field is the biggest overall one in China.Close attentions should be paid to the environmental situations of water quality,atmosphere,soil,vegetation etc.in the explorated area.Through traceably monitoring the enviromnmental situation of Fujiang cross section and Jiudaokan water reservoir for several years,the influences of the waste liquids produced in natural gas processing,drilling,downhole operation,gas-filed water,refining etc.on regional water environment are analysed,and the environmental contribution values of Fujiang and Jiudaokan water reservoir in the exploration area are obtained to provide a envirnmental management basis for further developing Moxl gas field.
