WELLHEAD TOOLS
Wire line Pressure Control Equipment
-
Brief introduction
Wire line Pressure Control Equipment is used to flowing oil well, gas well, water injection well and coal seams well for cable logging with pressure or paraffin removal operation, could supply pressure buffer and transition zone for string tools. In operation, the wellhead can be sealed when cable is static and dynamic state with pressure, or closed in the course of overflow and other unforeseen circumstances beyond controlling, to prevent blowout accidents. Operation conveniently and safety reliable.
The PCE is mainly consists of cable hydraulic seal head, tool catcher, lubricators, Tool Trap (includes of release assly with pressure), Blow Out Preventer, Top& Bottom Sheave, Pressure testing& releasing Assembly, Wellhead crossover flange (crossover sub), Lifting tool, Grease and Hydraulic Control Module，Transport and Storage Frame Skid, Pressure test plugs etc. -
Structure feature
- Sealing head apply manual pump to remote hydraulic compress seal stuffing, meanwhile, inject HP & high viscosity grease into space between chock tube and cable by Lincoln pump. Seal stuffing and sealing grease could seal cable by double intentions, which could guarantee operation safety and reliable.
- Includes of tool catcher and tool trap as double safety structure, in order to avoid string tool drop in well by accidently when run into lubricator.
- Pressure testing& releasing sub is used for monitoring wellhead pressure, releasing lubricator Residual pressure and pressure self-checking.
- Lubricator supply pressure buffer and transitional space for string tool, connect by fast union for combination.
- BOP is necessary wellhead pressure control tool which could prevent blow out accident.
- Includes of anti-freeze, unfreeze and pressure self-checking system.
- Equipped with fast pressure testing assly, which could improve PCE seal safety as fixing equipment or assembly & disassembly of lubricators. It help to avoid of second pressure self-checking for whole PCE.
-
Top& Bottom Sheave is made by Aluminum alloy, and has the advantage of preventing cable moved from slot.

Slickline Pressure Control Equipment
-
Brief introduction
Slickline Pressure Control Equipment is used to flowing oil well, gas well, water injection well and coal seams well for wire logging with pressure or paraffin removal operation, could supply pressure buffer and transition zone for string tools. In operation, the wellhead can be sealed when wire is static and dynamic state with pressure, or closed in the course of overflow and other unforeseen circumstances beyond controlling, to prevent blowout accidents. Operation conveniently and safety reliable.
The PCE is mainly consists of Slickline sealing control head, tool catcher, lubricators, Tool Trap (includes of release assly with pressure), Blow Out Preventer, Top& Bottom Sheave, Pressure testing& releasing Assembly, Wellhead crossover flange (crossover sub), Lifting tool, Hydraulic Control Module，Pedal assly, anti-freeze/ unfreeze and pressure self-checking system, Transport and Storage Frame Skid, Pressure test plugs etc. -
Structure feature
1). Sealing head apply manual pump to remote hydraulic control, to monitor wellhead seal result and guarantee of operation safety and reliable.
2). Includes of tool catcher and tool trap as double safety structure, in order to avoid string tool drop in well by accidently when run into lubricator. 3). Lubricator supply pressure buffer and transitional space for string tool, connect by fast union for combination.
4). BOP is necessary wellhead pressure control tool which could prevent blow out accident.
5). Includes of anti-freeze, unfreeze and pressure self-checking system, which could supply higher safety if operating in HP & complicated gas well.
6). Equipped with fast pressure testing assly, which could improve PCE seal safety as fixing equipment or assembly & disassembly of lubricators. It help to avoid of second pressure self-checking for whole PCE.
7). Top& Bottom Sheave is made by Aluminum alloy, and has the advantage of preventing cable moved from slot. -

Tubing Cock Valve
-
Brief introduction
Tubing cock valve is one type of manual control valve which used for open& close string circulating system. Normally, it is used to workover operation, which could prevent blow-out and close internal flowing liquid quickly for production safety.
-
Structure feature
Tubing plug valve could open/close by rotating external hex socket according to related mark.

Kelly Cock
-
Brief introduction
Kelly cock is one type of manual control valve which for drill string circulating system, could prevent blow out efficiently. It is divided by upper Kelly cock and lower Kelly cock. Upper Kelly cock is used below tap and above Kelly, lower Kelly cock is used below Kelly and above drill pipe or between above of Kelly protecting sub. Rotating 90 degree by professional wrench to open/close. In drilling operation, connect Kelly cock above and below Kelly could avoid blow-out accident.
-
Structure feature
Kelly cock sealing is by rigid coordination through ball valve body and ball seat, rubber seal is as assistant. Surface is compressed by spring. When in blow-out and close Kelly cock, pressure in well will force valve key to valve seat. Kelly valve sealing is better as higher of pressure to valve seat.
