Az31b Dissolvable Magnesium Alloy 70MPa Retrievable Bridge Plug

Large Diameter And Fast Dissolution Magnesium Alloy For Various Horizontal Wells

Introduction:

Magnesium alloy soluble material tools have high strength, good mechanical properties, solubility and other properties, which greatly promotes the progress of process technology, solves many problems existing in the current staged fracturing process, saves construction time, and improves production results.

Features and Benefits:

1. The soluble balls do not affect the flow of the edge of the bridge plug until they are dissolved;

2. It can prevent external dirt from entering the inside of the bridge plug;

3. The installation and positioning of bridge plugs during connection is more precise;

4. The mechanical properties and anti-extrusion ability of the outer surface of the bridge plug have been improved;

5. The stress generated by the bridge plug during the dissolution process is more evenly distributed, which improves the effect of the bridge plug during dissolution.

Application:

Combining new soluble materials, polymer degradable materials and high-strength ceramic technology, a plugging tool under a new concept is developed through the organic combination of mechanical properties, solubility and degradation properties. It is made of water-soluble metal material, and the rubber barrel is made of polymer degradable material, reaching a compressive strength of 70MPa. The bridge plug itself is completely decomposed within a certain period of time according to different material formulations, and the plugging of the reservoir is automatically released.

In order to reliably meet the basic requirements of bridge plugs in oilfield construction: they can be delivered, sealed, put into production, and eliminated, it is necessary to effectively control the performance parameters of newly developed products and the quality control of existing models. Carry out the detection of simulated downhole environment.
