Slickline BOP

Slickline BOP Manufacturer - Ruixin

Slickline BOP is connected with the wellhead connector or the top of the Christmas tree. When the steel wire or cable is still underground, closing the blowout preventer can seal the periphery of the steel wire (or cable), seal the pressure in the well and prevent the blowout.

Slickline BOP maintenance

1 maintain

After operation, completely disassemble the BOP and clean it. Check whether all sealing surfaces and sealing parts are intact with naked eyes. Found damaged parts should be replaced in time.

2. Replacement of gate seal:

(1). Remove the end cover;

(2) Knock out the ram assembly;

(3) Remove the fixing screw of the internal seal of the cable ram and take out the internal seal of the cable ram;

(4) Pull out the outer seal of the ram with a screwdriver;

(5) Install the replaced cable ram internal seal and ram external seal; Tighten the internal sealing fixing screw of the ram;

(6). Install the end cover and gate assembly into the lower shell;

3. Replacement of balance valve seal:

(1). Unscrew the slotted round head screw;

(2) Unscrew the valve core with a wrench;

(3) Replace the O-ring, apply grease and reload it.

Slickline BOP 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 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.

Slickline BOP Precautions

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.
