| 摘 要： | 根据封隔器解封过程中解封力在作业管柱中的传递特点,建立了带多封隔器作业管柱解封过程受力计算模型,给出了解封力在作业管柱中的分布规律和管柱变形量计算公式,利用Visual Basic语言编制了相应的计算软件。根据吉林油田某水平井实际作业参数,对带有多封隔器作业管柱解封过程进行模拟计算,并与现场监测值进行对比。结果表明,上提载荷和管柱变形量的模拟计算结果与监测值的误差分别为2.77%和3.10%,说明计算模型具有较高的计算精度,可以满足实际工程需要;在解封过程中,带封隔器作业管柱危险点出现在封隔器和造斜段位置,因此有必要对相应位置管柱强度进行校核。

| Abstract: | The force calculation model of the releasing process of the multi-packer horizontal-well operation string was established according to the characteristics of the transmission of the releasing force in the unsetting process of the packer. The distribution law of the releasing force in the operation string and the formula to calculate string deformation were given. The Visual Basic language was adopted to compile the corresponding computation software. A simulation calculation of the releasing process of the ... |
