摘　　要：随着常压页岩气藏的持续开发,彭水区块地层能量减弱,开采中需借助人工或机械举升方式。在气藏地质特征与开发现状分析的基础上,对彭水区块页岩气藏采用的优选管柱、电潜泵、射流泵和气举排采工艺现场试验特点进行研究,并展开成本分析与适应性评价。经研究,认为页岩气井投产后排采工艺可遵循以下原则:首选电潜泵工艺;次选射流泵工艺;若有条件,则选用优选管柱和气举工艺。With the continuing development of normal pressure shale gas reservoir in Pengshui block,the reservoir is gradually depleted. Artificial lift is necessary to maintain production. In the paper,based on analysis of the reservoir characteristics and present gas production,a comprehensive research on optimizing pipe string,gas lift,electric submersible pump and jet pump is conducted. Moreover,the related cost analysis and adaptability evaluation are conducted. For the selection of dewatering gas production technology,the recommended principles are as follows： the superior is electric submersible pump; the inferior is jet pump; for special cases,the optimizing pipe string and gas lift are desirable.
