A dissolvable magnesium bridge plug is a temporary sealing device used in oil and gas wells to isolate specific sections of the wellbore during operations such as fracturing, cementing, or well testing. It is designed to provide a temporary barrier that can be easily dissolved and removed from the well, eliminating the need for mechanical intervention to retrieve it.

Material: Dissolvable magnesium bridge plugs are typically made from a high-purity magnesium alloy. This alloy is selected for its ability to dissolve in downhole fluids, such as brine or acid, at controlled rates.
Construction: The bridge plug is designed as a cylindrical or tapered device, resembling a solid rod or cone. It is engineered with specific dimensions and sealing elements to fit and isolate the desired wellbore section.
Dissolution Process: When the dissolvable magnesium bridge plug comes into contact with wellbore fluids, the magnesium alloy reacts with the fluid, initiating a controlled corrosion process. This gradually dissolves the bridge plug over a predetermined period, allowing for the restoration of fluid flow.
Customization and Dissolution Rates: Dissolvable magnesium bridge plugs can be customized based on wellbore conditions, such as temperature, pressure, and fluid composition. The dissolution rates can be tailored to match the required operational timeline and environmental conditions.
Advantages: Using dissolvable magnesium bridge plugs offers several advantages. They eliminate the need for costly and time-consuming interventions to retrieve traditional mechanical bridge plugs. They also minimize the risk of formation damage during plug removal, enhance operational efficiency, and reduce environmental impact.
(1) Staged fracturing of horizontal wells is the main production stimulation measure for the development of low-permeability and unconventional oil and gas resources. Dissolvable Frac Plugs are the main technology for staged fracturing of horizontal wells. With the continuous development of low-grade resources, the length of the horizontal section and the number of fracturing sections continue to increase, and its importance becomes more and more prominent. (2) The main body of the All-Metal Dissolvable Frac Plug is made of high-strength soluble magnesium alloy, and the seals are made of soluble alloy materials, which are suitable for high-temperature or low-temperature oil and gas wells. The pressure-bearing performance of the seal exceeds 70MPa, and the dissolution rate after fracturing is adjustable and controllable.
