三联管

三联管是兴奋-收缩偶联中的重要结构，它由T管与邻近两侧的终池组成。

The triplicate-tube which is formed by T-tube and Terminal-cistern on its both adjacent sides is an important structure in the excitation-contraction coupling .

经现场应用，指出井斜大于30°的井，封隔器以上应加钻铤；三联作时下放管柱速度应小于0.4m／s。

By field application , it is indicated that drill collars are put on the packer when deviation of the well is more than 30 ° and down speed is lees than 0.4 m / s if tri-combination applied .
