监测井筒数据和传输井筒数据到地面
摘要：
本发明提供在钻井之后并且在随后的操作期间监测施加于井筒(12)中的部件(28)的力的方法。方法包括：提供管柱(35)，其包括管状构件(46)和装置(50)，所述管状构件(46)设有至少一个传感器(48)，用于测量所述管道中的应变，所述装置(50)用于传输数据到地面并且与所述传感器操作性地关联。将所述管柱运行到所述井筒中；监测所述传感器测量到的所述管道中的所述应变，并且补偿所述应变。利用所述管道在所述井中执行操作，包括：向所述井筒中的所述部件施力；监测所述传感器测量到的所述管道中的所致应变变化；以及使用所述数据传输装置传输与所述所致应变变化有关的数据到地面，以便于确定施加于所述部件的所述力。
摘要（英）：

Methods of monitoring a force applied to a component (28) in a wellbore (12) following drilling and during a subsequent operation. Methods comprising: providing a string of tubing (35) including a tubular member (46) having at least one sensor (48) for measuring the strain in the tubing, and a device (50) for transmitting data to surface and which is operatively associated with the sensor. Running the string of tubing into the wellbore; monitoring the strain in the tubing measured by the sensor and compensating for the strain. Performing an operation in the well employing the tubing, involving the application of a force to the component in the wellbore; monitoring the resultant change in strain in the tubing measured by the sensor; and transmitting data relating to the resultant change in strain to surface using the data transmission device, to facilitate determination of the force applied to the component.
