The track data generator bases on inertial navigation principles , and creates inertial components outputs by mathematic method 应用数学方法设计了一种仿真用井眼轨迹数据生成器，搭建了惯性器件模型，生成了模拟的惯性器件输出。
When the acoustic impedance of the fluid in borehole decreases , and other conditions keep unchanged , the acoustic energy in the borehole increases relatively 3 、当井眼流体的波阻抗降低而其它条件不变时，井内声场能量相对增强。
In part two , the acoustic field in and outside of a borehole is analyzed theoretically and numerically for the different physical model of the borehole 第二部分主要针对不同的井眼物理模型，对其井内外声场进行了数值模拟和理论分析。
Especially the perforating technology in the exceptional horizontal wells such as slim - hole casing wells , large hole wells and complex wells is detailed 着重介绍了水平井射孔技术在小井眼、大井眼及复杂井况条件下特殊井中的技术要求和特点。
The control of the trajectory is the core technique in horizontal well technique , while trajectory design and optimal design are the two key techniques 井眼轨迹控制是侧钻水平井技术的核心，而轨道设计与优化设计又是轨道控制技术的两大关键技术之一。
Rational interpretation of well track position in reservoir , changes of resistivity logging response and of porosity logging response are made by using xxx horizontal well as examples 以xxx水平井为例，对井眼轨迹在储层中的位置，以及电阻率测井响应和孔隙度测井响应的变化做出了合理的解释。
Viscosity should not be below 45 sec / qt . maintain with xcd rather than with bentonite . monitor hole cleaning at shakers and adjust low end rheology as required 要使钻井液粘度不低于每夸脱45秒，就要用生物聚合物来维护，而不用膨润土。通过振动筛观察井眼是否干净，按要求把最终的流变性调低些。
Horizontal well production forecasting formulas need to consider not only anisotropism and borehole eccentricity , but also the skin factor during drilling and completion process 摘要水平井产能预测公式除了要考虑储层各向异性和井眼偏心距的影响因素外，还要考虑钻井和完井过程中产生的表皮系数的影响。
