摘要 从理论上分析管柱在斜井中的受力,考虑到虎克定律效应、螺旋弯曲效应、温度效应等因素,计算油管上提高度、上提前地面已下放丈量油管长度、最佳坐封载荷和坐封高度,并编制相应的计算机程序,为现场估算钻具在井中伸长变形及确定封隔器坐封高度提供了一种简便计算方法。其计算结果与现场数据吻合。 Based on the theory, the paper analyses the force of the column in the deflected well in considering the effects of Hooke's law, helical buckling, and temperature, etc. It calculates out the back reaming height of the oil tube, the length of oil tube that has been put down from the surface of the earth before back reaming and the optimal setting load and height. We also compiled the corresponding computer program, which provides an easily calculating methods for estimating the distortion of drilling tools in the wellbore and determining the excluding height of packer setting at well site. The calculated results are closely fitting with the field data.
