Product introduction

The product is mainly composed of coupling, retaining ring, rubber cylinder, base pipe and other parts. It has a simple structure and can directly form a self expanding packer in case of oil and water with the base pipe and other parts. This product can be divided into water expandable rubber, oil expandable rubber and oil-water universal expandable rubber, as well as high-temperature and high-pressure type, low-temperature type, high salt type and other types to meet the requirements of different process conditions. It is widely used in oil, gas and water well completion, plugging and other operations. Main material: expanded rubber.

Product features

● Automatic expansion in case of oil or/and water.

● With simple structure, it can directly form a self expanding packer in case of oil and water with base pipe and other parts.

● The higher the temperature, the thinner the oil viscosity or the smaller the density, and the faster the expansion speed.

● The thicker the rubber body, the larger the outer diameter after expansion.

● The expansion performance is not affected by NaCI and other salts, and is not affected by acid concentration.
