Description
The most important equipment of underbalanced drilling system
Two structural forms:Single rubber core and double rubber cores.
Double-rubber-core rotation assembly has an upper and lower rubber core structure respectively, and it has the features of high-pressure sealing and stable rotation.
Single-rubber-core rotation assembly has the advantage of low well-drilling cost.
