[0002] In the oil and gas production operation, in order to ensure the safety of the environment in the well and the wellbore does not collapse, it is necessary to lower the metal casing into the well after drilling to support the wellbore. In addition, in some well drilling operations, downhole detection equipment needs to be lowered into the well together with the casing, and the power required by these equipment needs to be supplied by laying pipelines (such as hydraulic pipes and cables) outside the casing.
[0003] However, during the process of lowering the casing along the well, the pipelines outside the casing are easy to rub against the inner wall of the well, which will cause the pipelines to be worn, squashed, even torn or broken. These situations will cause the hydraulic pipe to leak or the cable to be unable to be electrified, resulting in the loss of power source for the downhole equipment. Whether the cable is connected and whether the hydraulic pipe leaks and whether the circuit is broken can usually be checked only after the casing is lowered, at which time the loss has already been caused; if the casing is pulled out again, the fault point is found and repaired before being lowered again, it will cause the delay of the construction period and the loss of property.
