Tension Sub

Tension is one of the items that must be measured during open-hole logging.
The tension sub is used to measure the tensile and compressive forces acting on both ends of the tool in the axial direction.
Facilitate the early detection of stuck or obstructed tool strings during the logging process, provide warning information for the system, and take emergency measures in a timely manner.

Judging Cable or Instrument Stuck Effective Solution

The Tension Sub from Vigor is used to correctly judge the status of the cable or instrument stuck in the logging process, which is of great significance to improve logging efficiency and reduce the logging cost.

In the real job, there is often a phenomenon that the instrument is stuck when it is run into the well or lifted, but it is difficult to distinguish whether the cable is stuck or the instrument is stuck in the process of lifting.

Suppose the correct measures cannot be taken according to the real status of the downhole string. In that case, the cable will risk being cut down or the instrument will be left in the well, which will seriously affect the furnishing of the logging task and increase the extra cost.

To detect stuck or obstructed tool strings early during the logging process, it promptly provides warning information for the system and takes emergency measures as needed.

Technical Properties

Vigor's Tension Sub boasts exceptional technical attributes that will assist clients in avoiding potential risks.

① Correct judgment of jamming status: It is used to correctly determine whether the cable or instrument is stuck during the logging process, which is crucial for taking timely measures to avoid further losses.

② Real-time monitoring: able to monitor the stress situation of downhole instruments in real-time, and provide timely feedback data for operators to make decisions.

③ Maximum tension range: capable of measuring the maximum tension that can reach a certain range, Max Tension is 25,000 lbf

④ Temperature and pressure resistance specifications: Temperature and pressure resistance specifications are important parameters for its ability to work in specific environments. Our company's products can operate in the temperature range of -20 ℃ -175 ℃ and can withstand a maximum working pressure of 20,000 psi

Tension Sub Working Principle

Tension Sub is usually connected to the lower end of the cable head and the upper of the telemetry. The axial tensile or compressive force received by any link of the tool string is transmitted to the tension sensor to generate an electrical signal, which is sent to the remote transmission tool.
