沁水盆地南部地区煤层气采出水治理的探讨

Discussion on the Treatment of Water Produced from the Coalbed Methane Wells of South District in Qinshui Basin

根据沁水盆地煤层气的生产实际情况,以不同水文地质单元、不同构造部位、不同井型和不同煤层气产出量为采样原则,有针对性地选择了生产区内6口生产井,对其煤层气采出水进行取样测试,发现该区域采出水物理性质较为单一,矿化度较高。基于环保与节能原则,并充分考虑成本控制因素,建议采用反渗透脱盐装置中加特定离子交换系统来进行水质处理。

According to the actual situation of coalbed methane production in Qinshui Basin,different hydro geological units,different structural parts of different type and different coalbed methane wells for sampling principle amount,the paper purposefully chose the production area of 6 production wells,sampling test of its coalbed methane produced water,found that the physical properties of the produced water in the region is single,higher salinity.Based on the principles of environmental protection and energy saving,and fully consider the factors of cost control,recommend using reverse osmosis desalination unit with specific ion exchange system for water treatment.
