水平井是永宁油田近两年建产的主要方式。通过具体对比分析永宁油田长6水平井与常规井产量、投资回收期评价水平井经济效益。根据近几年水平井的应用、总结近几年永宁油田水平井开发取得的成果及认识,探讨了水平段的长度、立体开发水平段的参数,为水平井的高效开发提供借鉴。
Horizontal well Yongning Oilfield is the main mode of production in the past two years. By comparing the output of Chang 6 horizontal well with that of conventional well in Yongning Oilfield, the economic recovery of horizontal well is appraised by the investment payback period. According to the application of horizontal wells in recent years, the achievements and understandings of the development of horizontal wells in Yongning Oilfield in recent years are summarized. The length of horizontal section and the parameters of horizontal development stage are discussed to provide reference for the efficient development of horizontal wells.
