Wireline Valve BOP
Alloy Steel&Nickel Alloy
China Baoji
Wireline & Slickline
Standard
The Wireline Valve BOP is a type of wireline pressure control preventer used in deepwater wells to prevent accidental kickout or blowout of drilling fluids and other drilling fluids from entering the water column. It consists of two ram-type assemblies connected by a flexible steel wire, which exerts pressure on the drilling fluid when the wire is pulled out of the wellbore.
1. Specification and model: 2FZ6.3-35-Y
2. Rated working pressure: 35MPa；;
3. Strength test pressure: 52.5MPa；;
4. Maximum applicable cable diameter: 7/32 ";
5. Operation mode: hydraulic control;
6. Working environment: standard;
7. Weight: about 100㎏.
The Wireline Valve BOP has several advantages over other types of pressure control preventers, including its ability to withstand high pressures and its low risk of cavitation. It is also relatively easy to install and maintain.
To use this preventer, the drilling crew must first connect the wireline to the bottom of the wellbore using a weighted swivel. Then, they must attach one end of the preventer to the wireline and the other end to the wellhead. When the drilling fluid reaches a certain pressure, the preventer will automatically release the wireline, preventing any accidental spillage.
1. Strength test:
(1) Install the pressure test joint and connect the pressure test pipeline;
(2) Start the pressure test pump for pressure test. The test pressure is 105MPa, and the pressure is maintained for 15 minutes. Fill in the test record card.
2. Performance test (gate sealing test):
(1) Manually close the ram and clamp the 7/32 "diameter polished rod in the sealing groove in the cable ram;
(2) Remove the upper and lower pressure test joints, press them from the 1/2 plug of the lower wing to 35 MPa, hold the pressure for 30 minutes, and fill in the test record card.
(3) After the test, clean up the internal residual moisture.
1. Check the internal and external seals and O-rings of the ram in time and replace them in time;
2. After each maintenance, performance test (gate sealing test) should be done;
3. Conduct strength test and sealing test regularly.
