Analysis on stress distribution of casing in sloughing formation with finite element method 易坍塌地层椭圆形井眼内套管应力的有限元分析
Analysis of decreasing torque effect and the location of non - rotating drill pipe protector in slim hole 小井眼钻杆保护器减扭效果与合理布置分析
A quantitative evaluation for excess pore pressure and wellbore stress around a cased well under steam injection 热采过程中地层超孔隙压力与井眼应力的定量评价
11drill the 36 ” hole with seawater , pumping 4 " 6 cubic meters high viscosity slugs for one string 在36英寸井眼用海水钻进，每钻一个立拄泵入4 6方的稠泥浆进行清扫。
With mud weights of 17 pounds per gallon hole cleaning will not be a problem and the use of sweeps will be superflours 用每加仑17磅左右的生钻井液，井眼清洁不会有什么问题，不必再配清扫液。
Wellbore track data and inertial components outputs are needed when continuous wellbore survey algorithms are simulated 为了对连续测斜算法的可行性进行仿真，需要井眼轨迹数据和惯性器件输出参数。
Usage : the centralizer makes the casing pipe at the center of the well . such can make cement ring even and better quality 产品说明用途：扶正套管使套管在井眼内居中，使水泥环均匀，提高固井质量。
All personnel are reminded that it is their responsibility to report any indications that are observed which may result in future hole problems 所有的人员都有责任汇报所观察到的任何可能引起井眼问题的显示。
This technology involves locating wells , optimizing sections , controlling well track and the function of drilling fluid 对接连通水平井钻井工艺技术涉及井位的确定、剖面的优选、井眼轨迹控制、钻井液性能等诸多方面。
