基金项目:页岩气勘探开发技术经济评价方法及其应用(CQGT-KJ-2012-4)
中文摘要:重庆目前是我国页岩气勘探开发的重点区域,目前有四个区块在进行页岩气勘探工作,我国首个页岩气田也位于重庆。页岩气赋存的特殊性决定了页岩气的开采必须采用储层改造技术,水力压裂是常用的储层改造技术,水力压裂具有高耗水的特点,重庆处于中度缺水区,水资源量具有季节性的特点,需要正确的评估页岩气开采对当地生产生活的影响。页岩气开采用水量虽占可用水资源量的比重不大,但是用水比较集中,仍可能对当地用水造成一定的威胁。本文在分析研究区水资源承载能力的基础上,提出了重庆地区页岩气开发的用水方案:尽量从流经该地区的流量大的江河中取水;加强返排液的处理利用;强化水资源管理,优化水资源配置。

Water Utilization of shale gas development - A Case of Chongqing
Abstract:Chongqing is the key area of shale gas exploration and development, currently there are four blocks for shale gas exploration, China"s first shale gas fields are located in Chongqing. The specificity of shale gas occurrence determines shale gas reservoir stimulation techniques must be used during shale gas development, hydraulic fracturing is a common reservoir stimulating technology. Hydraulic fracturing is high water consumption features, Chongqing is moderately dry areas, water resources have seasonal characteristics, it needs proper assessment impact of shale gas production and the local livelihood. The proportion of water using for shale gas development although accounted for the little amount of available water, more concentrated water, may still cause a threat to the local water. Based on the analysis of water resources carrying capacity , proposed water scheme in Chongqing shale gas development: trying to get water from large rivers flowing through the area; strengthen treatment and utilization of flowback; strengthen water resources management, optimizing water resource allocation.
