The first fractured shale gas well of China was constructed in 2010. After 10 years of
development, China has become the second country that possesses the core technology of …

Deep and ultra-deep reservoirs have gradually become the primary focus of hydrocarbon
exploration as a result of a series of significant discoveries in deep hydrocarbon exploration …

In this paper, the Lower Silurian Longmaxi shale samples and the backflow fracturing fluid in
the Changning Block of the Sichuan Basin were selected to investigate the damage …

摘要为了弄清压裂液返排过程中对页岩气储层裂缝的损害机理, 选取四川盆地长宁区块下志留统
龙马溪组页岩和压裂返排液, 利用压裂返排液对造缝岩样开展压裂液返排和气驱压裂液实验 …

Deep marine shale exhibits a higher proportion of nano-scale pores and limited natural
fractures, necessitating the utilization of hydraulic fracturing for effective stimulation …

Due to high salinity and complex components including varied inorganic salts, organic
agents, released heavy metals, radioactive elements and clastic particles, environmental …

液相圈闭损害一直被认为是致密砂岩气藏储层损害的重要机理. 由于储层物性特征及工作液类型
不同, 超致密砂岩气藏的液相圈闭损害程度和损害机理存在差异. 为此, 以塔里木盆地超致密砂岩 …

Organic-rich shale reservoirs are rich in reductive minerals, such as pyrite and other organic
matters. The working fluid for the development of shale gas reservoirs contains large amount …

富有机质页岩沉积于缺氧的还原环境, 富含黄铁矿, 绿泥石和有机质等还原性组分.
油气储层开发过程中有大量氧化性入井液进入储层, 与储层岩石流体不配伍 …

页岩储层富含有机质, 黄铁矿等还原性组分, 因而氧化溶蚀致裂是极具潜力成为一种新的页岩
油气层增产改造技术. 以往研究侧重于页岩氧化后孔隙结构及传质能力的变化 …
