API Oilfield Drilling Rig FZ35-70 Ram BOP or Blowout Preventer
Main Introduction
BOP is shut in the well for oil testing, workover, well completion and operating process to prevent the blowout accident, totally enclosed and semi-closed two functions into one, has a simple structure, easy to operate, resistant to high-pressure characteristics is used to prevent blowouts safety oilfield sealing wellhead.
Oil drilling, installed at the wellhead casing head, used to control the high pressure oil, gas, water blowout. Wells of oil and gas pressure is high, the BOP can be the wellhead closed (shut). The shutter has four, alternatively bullied invaded mud, increasing the pressure of the borehole fluid column, so as to suppress the high-pressure oil and gas discharged from the drill pipe is pressed into the heavy mud.
Its type sub-ordinary blowout preventer, of universal blowout preventers and rotating blowout preventer. Ordinary BOP ram with full-and semi-closure, full closure type blowout preventer can seal the entire wellhead; semi-sealed shut wellhead annular cross-section of drill pipe exists. Universal BOP can start in case of emergency to cope with any size drill and empty wells.
Operating Requirements of TR Drilling BOP:
- Make regular pressure test on the annular preventer according to relevant standards.
- It's feasible to control wellhead with annular preventer firstly when blowout occurs in a well where there are drilling tools, but try not to seal it for long, because rubber core is fragile and there is no locking device. Don't close empty well with it in non-special cases.
- It's necessary to use a drilling tool with an 18-degree slope when annular preventer is used for snubbing tripping operation. Tripping speed should be slow when passing through joints, and all the rubber sleeves of the drilling tool should be uninstalled.
- When annular preventer is in an off state and shut-in pressure is below 5Mpa, it's feasible to move the drilling tool up and down, but don't rotate it.
- It's necessary to wash the inner cavity out to keep the switch flexible after well cementation and leaking stoppage, etc.
- Be sure to pay special attention to sealing backing ring and steel ring groove when installing or uninstalling annular preventer, which cannot be cracked up or scratched.
