Product Description

IBOP For Top Drive (Upper/Lower Safety Valves)

IBOP for top drive can be divided into Upper IBOP and Lower IBOP; they are control valves which are used with the top drive system. Usually the two valves connected to the top drive drilling device. The IBOP adopts high reliable metal seal. Soit can bear high pressure upward and downward. The working pressure can be achieved 10000 psi or 15000 psi. When well kick occurring, the upper IBOP can be closed by remote controlled, but the lower IBOP will be closed manually. Actuator for top drive is a subsidiary body which controls open and close of Upper IBOP. It works with other accessories of the rig, so that control opening and closing of Upper IBOP on any height of derrick driller console. Both the valve body cavity and accessories have special anticorrosive processing, so that prolong the working life.

Actuator
Actuator is a driving tool supporting the use of top drive system, and it consists of actuator and crank. It drives the actuator by the top drive hydraulic system, and the actuator controls open and close of the inner ball valve in Upper IBOPs by rotating of crank mechanism. It is reliable to work and easy to handle.
Specification
Working with Φ187,Φ197,Φ216 IBOP for top drive.

Top drive Floating Cushion Sub
Top drive floating cushion sub an important tool in drilling operation.It is suit to the drilling process in oil, gas and geological exploration. Mainly used for top drive drilling operation. It can increase the working life of bearing and gear in top drive rotary box. Specification:

Hydraulic Casing Running Tool(internal)
Hydraulic Casing running tool is a new technology for running casing. We developed the more safe and efficient internal casing running tool to break the limitation of normal running casing operation. This technology could develop all the advantages of top drive drilling, make the casing string rotating, lift and circulating the mud simultaneously, insure the casing could be running to the well bottom normally, improve the success rate, safety and efficiency of casing running observably. It has a wide introduction value to the oil field.

  Mechanical Casing Running Tool(External)
Mechanical Casing running tool has a new technology for running casing. For the limitation of normal running casing operation, we researched and developed this casing running tool which has advantages of safety and high-efficiency. It clamps on the coupling's outside by internal teeth of slip. Making the casing string rotating and circulating the drilling fluid in the same time. It can insure the casings running to the well bottom normally. It improved the success rate, safety and efficiency in running to the well bottom normally. It improved the success rate, safety and efficiency in running casings operation. It only needs four kinds of slip head, eight kinds of slip teeth to running all sizes casings. Our casing running tools are well used in Liaohe and other domestic oilfield.
Notes: Supporting accessories including floating cushion sub, intelligent monitoring system, Mud splash-proof valve.
