Staged fracturing of horizontal wells is the main production-increasing measure for the development of low-permeability, unconventional oil and gas resources.
The main body of the all-metal soluble bridge plug is made of high-strength soluble magnesium alloy, and the seal is made of soluble alloy material. It is suitable for high-temperature or low-temperature oil and gas wells. The sealing pressure-bearing performance exceeds 70MPa and can reach 105MPa.
The seal is completely dissolved, and the dissolution speed after fracturing is adjustable and controllable.

Features
- The full range of all-metal dissolvable bridge plugs are in various specifications such as φ85, φ88, φ98, φ102, φ108 (according to customer needs), which can meet the needs of staged fracturing of different well diameters;
- The all-metal dissolvable bridge plug is adapted to the Baker #20 setting tool. The length of the bridge plug body is small and the setting displacement is short;
- Compared with the rubber cartridge sealed dissolvable bridge plug, it has “lower low temperature resistance and higher high temperature resistance”, and more complete dissolution after pressing, truly achieving “full soluble”;
- Compared with similar foreign products, “small diameter sealing of large wellbore” has obvious advantages.
