Electroless nickel plating is a good protection method for dissolvable magnesium
Magnesium alloy is an ideal dissolvable material with high specific strength, low density, fast dissolution and excellent casting performance.
After fracturing dissolvable Magnesium alloy fracturing bridge plug dissolves by itself without milling, which can greatly reduce construction risks and costs, it has obvious advantages in fracturing and reconstruction of oil and gas reservoirs.
However,before fracturing operation the soluble bridge plug should maintain its integrity during transportation and well entry, the plug body do not allow to react with external solutions to avoid functional failure.
During the entering the well, the bridge plug will rub against with the well wall, the plug surface is easy to be damaged, so it is very important to protect the surface of soluble metal bridge plug.
Electroless nickel plating is a good protection method for dissolvable magnesium alloy,
The nickel layer on the magnesium bridge plug can be used to protect its surface and also could control the dissolution time
