Sulfonated Asphalt

Описание

Sulfonated Asphalt plays an important role in the drilling industry. It is a special asphalt product that has been chemically treated. By introducing sulfonic acid groups, it gives the asphalt excellent properties, allowing it to play a unique role in the drilling process.

As a sealing agent, Sulfonated Asphalt can fill cracks and pores in wellbores. This can effectively prevent the leakage of groundwater, oil or gas. Its high viscosity and adhesive properties allow it to form a reliable isolation barrier. To ensure safety during drilling and controllability of operations.

In addition, Sulfonated Asphalt is also widely used as a leak-stopping agent. In the event of leakage on the well wall, it can quickly penetrate into the leakage point and form a solid leakage-stopping layer. This capability is critical to controlling formation pressure, preventing wellbore inrush, and avoiding environmental contamination.

The application of Sulfonated Asphalt in drilling also includes cementing processes. It is mixed into the cement slurry as an additive during cement cementing. This improves the viscosity and adhesion of the cement slurry. This helps ensure that the grout creates a strong seal between the formation and the casing. Prevent dangerous situations such as fluid leakage and pressure loss from occurring.
