Abstract

The invention provides an anti-corrosion and anti-scale titanium-copper alloy material. The anti-corrosion and anti-scale titanium-copper alloy material comprises the following components with contents in percentage by mass: 25-40% of titanium, 20-30% of copper, 10-25% of zinc, 10-15% of nickel, 2-5% of tin, 1-5% of tellurium, 0.01-3% of aluminium, 0.01-0.8% of indium, 0.3-0.5% of niobium, 0.01-0.3% of silicon, 0.01-0.5% of scandium, 0.1-1% of depleted uranium, 0.5-1.5% of the mixture of NaF and NaCl, and less than 0.1% of inevitable impurities. The material is excellent in anti-corrosion and anti-scale performance, capable of slowing down the corrosion of water in the case of being placed in produced water, and capable of reducing the corrosion of solution in the last period of oil and gas development, and reducing the scaling of the solution to equipment.

Description

technical field [0001] The invention belongs to the field of anti-corrosion and anti-scaling materials, in particular to an anti-corrosion and anti-scaling copper-titanium alloy material used in the production process of oil and gas fields. Background technique [0002] As oil and gas fields enter the high water cut stage in the middle and late stages of development, oil and gas field water treatment has become the main means to maintain formation pressure and increase oil field production. However, the corrosion and scaling problem caused by the water treatment process is a common and serious problem at present, which has brought serious safety threats and economic losses to oil and gas field production. In oil and gas field production systems, corrosion and fouling often occur simultaneously. Therefore, it is particularly important to develop a new material that can have both anti-corrosion and anti-scaling functions. [0003] At present, most of the anti-corrosion and a...
