Degradable Downhole Tool

This patent relates to downhole tools that combine reactive metals and degradable resins. The tools use degradable resins containing polyglycolic acid and reactive metals such as magnesium, aluminum, and calcium. This allows for efficient processing within the well, and after use, the tools can be easily decomposed and removed. Inorganic salts (such as potassium chloride and sodium chloride) promote the decomposition of reactive metals, reducing the workload and lessening environmental impact.

• Combination of reactive metals and degradable resins
• Inorganic salts promote metal decomposition
• Characteristic of natural decomposition after use

Conventional downhole tools are difficult to remove after use and involve a considerable amount of work. They also have a significant environmental impact. Particularly in high depths or harsh environmental conditions, the performance of the tools often becomes unstable. This can lead to reduced efficiency in recovering oil and natural gas, increasing costs. Furthermore, the tools do not decompose naturally after use, raising concerns about negative environmental effects.

This patent solves conventional issues by providing downhole tools that combine reactive metals and degradable resins. By using degradable resins containing polyglycolic acid and reactive metals such as magnesium, aluminum, and calcium, processing within the well can be conducted efficiently. Furthermore, inorganic salts (such as potassium chloride and sodium chloride) promote the decomposition of reactive metals, resulting in easy decomposition and removal of the tools after use. This reduces the workload and lessens the environmental impact.

• Technology that ensures reliable well treatment
• Technology that allows for easy removal after use
• Technology that reduces the workload
