彰武工区快速钻井工艺技术

Fast Drilling Technology in Zhangwu Work Area

摘要:

针对彰武工区部分断陷地层含砾，易斜、易塌、易漏，研磨性强等特点，通过建立地层可钻性及三压力剖面，推广试验高效钻头、单弯螺杆加PDC钻头复合钻具、新型堵漏材料及堵漏措施等，为快速钻井奠定了基础，并形成了彰武工区快速钻井工艺技术系列。

Abstract:

According to the characteristics of gravel, inclining, collapsing, leaking and strong abrasiveness in part of fault depression interval in Zhangwu work area, by establishing drillablility and three pressure profiles, the compound drilling tool of high efficient bit, single bend PDM PDC bit and new material & the measures are tested and promoted, which lays the foundation for the fast drilling to form a fast drilling technology series in Zhangwu work area.

Key words:fast drilling; drillability profile; three pressure profile; leakage stoppage; inclination prevention; PDM drill; high effective bit; Zhangwu work area
