(1) BOP-site use to designate a person responsible for implementation of the responsibilities, the user will want to achieve three transverse four (to understand the working principle, to understand performance, understand the process; to operate, maintains, will be maintenance, troubleshooting will ).
(2) When no tube wells to the test tube gate closed, the maximum fluid pressure control can not exceed 3MPa, to avoid damage to the plastic core. When wells are string, the non-closed gate off the whole.
(3) automatic locking of the hydraulic blowout preventer plugging takes a long time, should close the gate of the hydraulic control pressure up to 9.5-10.5MPa, BOP hydraulic cylinder to be closed cavity pressure is stable, you can vent out hydraulic control pressure, BOP can automatically lock.
(4) after each drill to be done from the closed gate pull switch all test wells have shut down the whole column when the closure gate is strictly prohibited.
(5) not allowed to open the gate way to relief, so as not to damage the plastic core. Open the gate between the plate after going to check whether the fully open position (all back to the shell), to avoid drill Sunhuai gate.
(6) to keep the park clean hydraulic.
(7) Used after BOP should make gate fully open position for maintenance.
