在石油勘探与开发中,测井作业是一项至关重要的技术活动,电缆井口张力作为测井过程中的一个重要参数,是判断测井作业安全的一个重要指标.采用最小曲率法,对井眼轨迹进行了插值计算,构造了电缆在不同井深处的三维曲线.采用软杆模型,对微段电缆进行受力分析,提出了电缆井口张力的计算流程.研究结果表明:对于上提和下放工况,测井电缆井口张力均随着井深的增加而增加,且上提张力远大于下放张力.张力计算结果与国外Cerberus软件、实测数据进行了对比,验证了计算方法的可行性.研究成果为我国测井行业专业软件开发提供了技术支持.
Calculation of Cable Tension in Logging Operations
In oil exploration and development,logging operations are a crucial technical activity,and cable wellhead tension,as an important parameter in the logging process,is an important indicator for judging the safety of logging operations.The minimum curvature method was used to interpolate the wellbore trajectory and construct three-dimensional curves of the cable at different depths of the well.Using a soft rod model,a force analysis was conducted on the micro segment cable,and a calculation process for cable wellhead tension was proposed.The research results indicate that for both upward and downward working conditions,the wellhead tension of logging cables increases with the increase of well depth,and the upward tension is much greater than the downward tension.The tension calculation re-sults were compared with foreign Cerberus software and measured data,verifying the feasibility of the calculation method.The research results provide technical support for the development of professional software in China's logging industry.
