近日,由西部钻探承担的全过程工程技术施工作业,国内首组大尺寸SAGD水平井FHW3122P/I井组告捷。FHW3122P/I井组是新疆油田2014年在风城油田重45井区部署的一组试验性SAGD水平井,也是西北地区首组大尺寸SAGD水平井。其中,FHW3122P井设计井深1 489 m,FHW3122I井设计井深1 467 m。FHW3122P/I水平井二开、三开井眼尺寸由常规设计直径311.2 mm、215.9 mm增加到直径444.5 mm、311.2mm。2014年,西部钻探在认真总结往年SAGD水平井技术服务成功经验的基础上,持续完善技术方案和操
Recently, the entire process of engineering and technical construction undertaken by Western Drilling won the first batch of well-developed FHW3122P / I Well of the first large-size SAGD horizontal well in China. Well FHW3122P / I is a set of experimental SAGD horizontal wells deployed in Weizeng 45 well area of Fengcheng Oilfield in 2014 by Xinjiang Oilfield and also the first large-scale SAGD horizontal well in Northwest China. Among them, the designed depth of FHW3122P well is 1 489 m, and that of well FHW3122I is 1 467 m. FHW3122P / I horizontal well two open, three open borehole size from the conventional design diameter 311.2 mm, 215.9 mm diameter 444.5 mm, 311.2mm. In 2014, on the basis of earnestly summing up the successful experiences of technical service of SAGD horizontal wells in previous years, Western Drilling continued to improve the technical solutions and exercises
