2014年5月8日,中国石油天然气集团公司塔里木油田塔中862H井顺利完成1 502m的一开钻探任务。这口井成为我国陆上设计最深的水平井。为解开塔中深层地带地质密码,塔里木油田推广应用科技成果,设计了塔中862H井。这口井设计井深8 008m,垂深6 325m,水平段长1 557m,目的层为上奥陶统良里塔格组。其旨在探索塔中861号奥陶系缝洞系统的含油气性,获得产能、流体性质及物性等资料。 On May 8, 2014, Well No 862H of Tarim Oilfield of China National Petroleum Corporation successfully completed a drilling project of 1 502m. This well has become the deepest horizontal well in China’s land design. In order to solve the geological code in the deep zone of Tarim Basin, Tarim 862H well was designed to promote the application of scientific and technological achievements in Tarim Oilfield. The well is designed to be 8 008 m in depth, 6,325 m in depth, and 1 557 m in horizontal section. The target formation is the Upper Ordovician Lianglitage Formation. The purpose is to explore the hydrocarbon-bearing properties of the 861 Ordovician seam-cavern system in Tazhong and to obtain the data of productivity, fluid properties and physical properties.
