7" 10000psi Drill Stem Test Tools Full H2S service Retrievable Safety Joint
Introudction of retrievable Safety Joint
The 7" x 10000 psi retrievable Safety Joint is the optional backoff tool of DST work string in the well testing service. When the test packer is stuck during the testing operation, the retrievable safety joint is able to disconnect the drill string above the packer, the 7" retrievable safety joint made of Inconel steel with 10000 psi working pressure can be used in full H2S DST service.
Feature of the retrievable Safety Joint
* The retrievable safety joint is with full bore design
* The tensile load of the retrievable safety joint should be predetermined
* Tools above the retrievable safety joint can be retrieved when string is stuck.
* The safety joint can serve in the Full H2S oil and gas well
Operation of the tension safety joint
When running the tension Safety Joint with Tubing Conveyed Perforating, calculate the string weight below the RTTS Safety Joint. The string weight below the tension Safety Joint should not exceed 30% of the tension Safety Joint tension sleeve rating.
Application of the Tension Safety Joint
* Full H2S Drill stem testing Operation
* TCP operation
* Well Completion operations in Full H2S
