Single Pressure Sealant

Product name: Single pressure sealant

Product code:

Role category: It is an oil and gas layer protection material, also known as shielding temporary plugging agent.

Product Classification: Type I; Type II.

Key features:

Utilizing the overall pressure difference, the one-way pressure sealant added in the mud is pressed into the pore throat of the oil and gas formation, forming a zero-permeability closure zone at the attachment of the well wall, preventing the solid phase and filtrate in the mud and cement slurry from continuing to leach into the oil and gas formation, so as to achieve the purpose of protecting the oil and gas formation.

key features:

The main components of the one-way pressure sealer are calcium carbonate and asphalt powder, paraffin, and resin, all of which are smaller than the diameter of the orifice throat.

Additions: 3%-5%

Usage: 20 meters before entering the hydrocarbon destination layer, added to the mud at once.

Production process:

Plant fibers are added with dilute acid solution and reacted under certain temperature and pressure, then neutralized, dried and crushed to get the finished product.
