Packer elements refers to a downhole tool seal connected to the downhole string and used to seal the annular space between tubing and oil and gas well casing or open hole wellbore. In oil production engineering, the packer is used for layering, and an oil production channel is designed on the packer. When setting, the piston sleeve goes up and the oil production channel is opened; After setting, t...

When it comes to sealing in harsh operating conditions, the Upstream Oil & Gas industry has some of the toughest applications out there. With fluids such as hydrocarbons and gases such as H2S, combined with pressures climbing well above 20k psi and temperatures drifting to 200° C and higher, reliability in sealing is an absolute must to mitigate against unproductive downtime. Adding steam and ...

Guangzhou JST Seals offers downhole sealing solution and products. Bottom hole assembly (BHA) tools (such as impactors and jars) need to be sealed to protect the tool hydraulic system from the impact of abrasive drilling mud and cuttings in the hole. Measurement while drilling (MWD) tools sometimes need high-temperature sealing solutions. This field operation is expensive, If seal failed it would ...

The chemical name of polytetrafluoroethylene is PTFE (polytetrafluoroethylene). It has the highest chemical resistance and heat resistance, and can resist almost all aggressive substances. PTFE has low lubrication and high sliding speed. Wear resistance is usually low, and PTFE materials are prone to cold flow under pressure. JST Seals can produce PTFE fillers such as carbon fiber, graphite, bronz...
