Soluble alloy material (soluble alloy material)
Soluble alloy materials include soluble spheres, soluble rods, soluble profiles, and many other types of self-owned grades. The technical parameters such as pressure resistance, temperature resistance, tensile strength, and dissolution rate can be customized according to customer needs. It can be dissolved in an aqueous solution containing electrolyte and different liquid environments, with different compositions and different mechanical properties. Various types and different grades of available soluble balls, soluble bars, soluble profiles, etc. meet the different needs of customers. Structural parts made of soluble alloy materials, in addition to good solubility properties, also have high strength and plasticity.
In recent years, bridge plug technology based on soluble materials has gradually gained popularity, but there are currently a dazzling variety of products on the market, and the following problems exist in specific field applications:
· Bridge plug dissolution residue: The bridge plug body in the wellbore is not completely dissolved, and there are many residues;
· Sealant cartridge: The bridge plug rubber cartridge is not completely dissolved, and it is difficult to handle in the later passage of the well;
· Small diameter: during the blasting after the fracturing, the formation of sand will easily block the bridge plug channel, which is unfavorable for the bridge plug to dissolve.
