PRODUCTS CENTER

Managed Pressure Drilling (MPD) is a drilling method that precisely controls wellbore pressure within a safety window. It rapidly identifies and manages pressure imbalances to prevent well blowouts, internationally recognized as the optimal solution for complex well control challenges.

Papua New Guinea Rotating BOP

The PETROZHR Rotating control devices (RCDs) create a closed and pressurized system, which gives you ultra-precise control over fluids flowing into and out of the well. Design and manufacture of type FX series rotary blowout preventer complies with NACE MR0175, API Spec 6A/ISO13533, API Spec 16RCD and GB/T25430-2010.

Papua New Guinea Float Valve Sub

Float Valve Sub is an important tool in petroleum exploration and drilling engineering. The float valve sub is connected at upper part of drill bit. The float valve sub is near the bit connecting thread. The float valve sub can also be used at different necessary position of drill string when required. The main application is, when connected with single piece pipe, it prevents mud from coming in and up blocking the hole. When blowout takes place, blowout in drill string will be avoided because nozzle is closed automatically by valve cap of the float valve assembly .

Papua New Guinea Drop-in Check Valve

Drop-In Check Valves prevent return flow during a kick and are suitable for most drilling situations in which return flow through the drill string is a risk and normal operation requires the benefits of a full-bore sub. By preventing upward flow through the drill pipe, but allowing fluid to be pumped downward to circulate the well, the valves provide the driller with the means to control the drill pipe pressures when required, significantly improving and simplifying well control. When blowout is going to be happened，the thread connections of the kelly is screw out immediately and put the check valve is into the drill pipe and then pumped downward to the required place．Thus the blowout can be prevented.
