Packer elements are rubber seals that operate under specific down-hole conditions and provide an elastomeric seal for either short-term or long-term completion. Packer elements are used between sections of oil and gas production tubing to prevent fluids and pressure from leaking through the joints. This protects the casing, production tubing, liner and wellbore wall above and below the p...

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...

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 ...

Packer is one of the most common and essential tools in the process of oil recovery, water shutoff and water injection. It is used throughout the whole process of oil and gas exploration and development, especially in the well completion. The main part of the packer is the packer element, which is made of rubber with good elasticity. It is set in the annular space of casing and tubing by means of ...

Centralizer fin is a necessary tool for downhole oil production and plays a very important role in the field of oil drilling and production. The oilfield centralizer fin is mainly used to centralize the tubing in oil-water deviated wells to prevent the abrasion of tubing and casing wall caused by tubing creep during oil pumping and the cleaning of casing inner wall. Due to the complexity of well c...
