Sodium Polyacrylate for Oilfield Drilling

With the continuous expansion of the field of oil exploration, the drilling depth has gradually increased, and there are more and more oil-poor mines, and the difficulty has also increased. Moreover, the crude oil produced now accounts for a large proportion, and it is difficult to extract and transport it.

Super absorbent resin has many excellent properties such as water absorption and oil absorption and can be used as many oil recovery chemical agents, such as demulsification and oil displacement agents, dispersing agents, water treatment agents, drag-reducing agents, viscosity reducing agents, pour point reducing agent, etc.

SAP can also effectively remove a small amount of water in the oil. Add SAP to the kerosene containing a small amount of water, and fully stir and filter out the resin to obtain oil with all the water removed.

Synthetic polymer resins such as polyacrylonitrile and polyacrylamide can control the viscosity and water holding capacity of the mud, as well as flocculation.

More importantly, they also have resistance to bacterial damage and thermal stability and are widely used in oil fields. The disadvantage is that they are sensitive to polyvalent metal ions and are prone to react to produce precipitation.

Sodium polyacrylate is the most widely used superabsorbent resin due to its macromolecular structure with few branches and long linear flexible chains, and excellent drag reduction effect.

SAP can also be combined with inorganic powder particles to make water-absorbing composites, which can be used as a Rapidly gelling water-blocking agent.

In addition, SAP can also be used as a chemical plugging material in oil fields.
