The currently used methods for calculating gas injection rate during gas drilling all take the temperature of natural formation at the same depth as the temperature of the annulus fluid,without considering the heat exchange occurred between the wellbore fluid and the formation.
目前关于气体钻井时所需注气量的计算方法均是将环空流体的温度取同一深度的自然地层温度来进行计算,没有考虑井眼内流体与地层进行换热的影响,这必然会带来误差。
Results show that with the increase of eccentricity between reaming tool axes and well bore axes,or with the decreas.
为了解随钻扩眼工具在井眼内的运动状态和受力情况,促进钻井工具的优化设计和更合理的应用,对随钻扩眼工具在井眼内的运动进行了研究,给出了基于拉格朗日方程的动力学分析方法;基于法向接触约束的惩罚准则,计算了扩眼刀翼与岩石之间的接触力,对随钻扩眼工具在井眼内的运动过程和动力响应进行了动力学仿真研究。
This article introduces two techniques of determining the-directions of natural fractures:One is micro-fracturing and oriented coring,the other is measuring the elliptic axis of the well bore by dipmeter logging.
在裂缝性地层，效益最好的水平井，其水平井井眼应与天然裂缝面垂直，这样可大大减少油气渗流阻力，充分发挥各个裂缝面的最大泄油效能。
