II.peculiarity

The Double Wing Blowout Preventer 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.

The Double Wing Blowout Preventer 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.

III.Product Testing

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 5/16 "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.

IV. Precautions

1. Disassemble BOP after operation and clean the parts. Check the sealing-face or seal parts carefully. Replace the worn parts in time.

2. After each disassembly, it is a must to conduct the seal test.

3. Strength test must be conducted on time.
