The Wireline Grease Injection Control Head is used to inject sealing grease into the choke pipe to lubricate the cable and seal the ground control equipment of the wellhead.
1. After use, unscrew the upper connector, the coupling and the lower connector;
2. Take out the choke tube and check the O-ring;
3. Replace the damaged parts and reload them;
4. Carry out a sealing test with a test pressure of 35MPa.
able is guaranteed to be 0.1-0.2mm. For cables of different diameters, choke tubes with different inner diameters should be selected. And due to the wear between the choke tube and the cable, the choke tube should be checked regularly;
2. When using it again after long-term storage, the strength test should be carried out.
1. Install the pressure test connector and connect the pressure test pipeline;
2. Start the pressure test pump for pressure test, the test pressure is 70MPa, the pressure is maintained for 15min, and the test record card is filled in.
