摘要
本文根据渤海某油田地层特点,综合比较了常用的螺杆钻具、支撑式和指向式旋转导向工具特点、特性,重点介绍了依据油田浅部疏松地层、造斜困难,中部地层砂泥岩互层,稳斜角大、稳斜段长和水平段储层发育等作业特点,优选合适定向井工作。
This article describes the properties of screw drill,supported and directional rotary steering tools based on thecharacteristics of formation in XX Oilfield. It focuses on the directional well,which is selected due to the features of the oilfield suchas loose formation,difficult build-up in shallow formation,sand-mud interlayer in mid formation,large stability angel and slope aswell as reservoir development in horizontal formation.
