2014年2月19日,中国石化胜利石油工程西南分公司圆满完成国内最深页岩气井——南页1HF井钻井施工任务,实际完钻井深5 820m,将中国石化页岩气勘探开发推进到新的深度,并创出多项高新纪录。南页1HF井位于重庆市南川区铁村乡,是华东石油局在四川盆地川东南构造带南川断鼻部署的重点水平预探井,目的层位是上奥陶统五峰组至下志留统龙马溪组,设计井深5 712.56m,最大井斜77.99°,水平段长达1 047.91m。
On February 19, 2014, SINOPEC Shengli Petroleum Engineering Southwest Branch successfully completed the drilling of the deepest shale gas wells in China - South Page 1HF Well Drilling. The drilling depth was 5 820m, pushing Sinopec shale gas exploration and development to new Depth, and hit a number of high-tech records. South Page 1HF well is located in Ticun Village, Nanchuan District, Chongqing City. It is a key horizontal pre-exploration well deployed by East China Petroleum Bureau in the Nanchuan fault structure of southeastern Sichuan Basin in Sichuan Basin. The purpose of this site is to identify the Upper Ordovician Wufeng Formation to the Lower Silurian Creek group, the design depth of 5 712.56m, the maximum deviation of 77.99 °, the horizontal section of up to 1 047.91m.
