| 摘 要： | 为了实现彭水区块页岩气井快速排液，降低压裂液对储层的污染，提高返排率，促进页岩气快速解吸，在分析彭水区块页岩气藏基本特征和生产特点基础上，分析了低压页岩气井不同生产阶段的生产特点，并从工艺上提出了不同的解决方法，形成了彭水区块页岩气井压裂后快速排液、稳定降压和自喷生产的“三段式”排采方式。该排采方式在彭水区块3口已投产页岩气水平井现场应用后，取得了较好的开发效果，为彭水区块低压页岩气井的有效勘探和开发提供了新的技术支持。

| Abstract: | In order to realize fast liquid drainage,reduce the reservoir damage of fracturing fluid,increase the flowback rate and promote the rapid shale gas desorption in Pengshui Block.Through analysis of shale gas reservoir characteristics and production characteristics in the block,the principle of low-pressure shale gas wells in different production phases was investigated,and different technical solutions were presented.Finally,a "three-stage" drainage method(namely,rapid drainage after fracturing,stable pressure dropping and flowing production)was formed.Till now,the drainage method has been effectively applied in 3 shale gas wells in Pengshui Block.It provides new technical support for effective shale gas exploration and development in Pengshui Block. |
