Natural gas leakage shut down devic
- This device could be widely used to prevent flammable and explosive fluid leakage in oil and gas drilling, transportation, storage and processing industries.
Gas well downhole choke
- The tool is located at the desired locations through slick line operation, and sealed by rubber joint, to realize pressure releasing and throttling.
- It is mainly applied for separate well testing, separate layer recovery, water finding, water blockage, fracturing, acidizing and sand control.
- It is used in downhole operation and can prevent pipe string axial displacement.
- It is used for downhole layered water distribution, separate zone injection, channeling blockage, chemical water blockage and acidizing operation, etc.
- Slips type and mandrel type satisfy different working conditions.
Double-diameter hydraulic drilling
- This product is fit for deviated wells and intervals where the drilling tools are easily stuck, and it avoids accident of stabilizer sticking in directional wells and improve buildup rate
