摘要
水平井技术在非常规油气勘探开发中发挥着重要的作用,但非常规油气水平井的水平井段长、井网控制程度低、轨迹要求平滑的特点给地质导向带来较大的困难。文章分别论述了地质导向设计编制、入窗前轨迹调整和水平段导向三个阶段的主要研究工作,并在此基础上,探讨了A靶深度的确定、水平段方位伽马和成像导向的技术方法,这些方法在泌页HF1井中取得了较好的应用效果。
Horizontal well technology plays an important role in unconventional oil and gas exploration and development, but it has the characteristics of long horizontal section, low well pattern control degree and smooth trajectory, which brings great difficulties for geosteering. Therefore, in this paper the geosteering design preparation, the trajectory adjustment before casing windows sidetracking and the direction of horizontal section have been respectively discussed. On the basis of the discussion, the technology methods on A target depth determination, azimuth gamma of horizontal section and imaging direction have been further discussed. The application results show these methods have achieved good effects in Bi-ye HF1 well.
