Problems solved by technology

At present, the flow rate of the wellhead is large, and a large amount of sediment will be mixed in the process of oil discharge. Due to the fast flow rate, the long-term erosion of the wellhead by the sediment will cause the wear of the wellhead. Once the wellhead is damaged, it will cause oil and gas leakage, which will not only cause waste of resources and pollute the environment

Description

technical field [0001] The invention relates to the technical field of wellhead devices, in particular to an erosion-resistant anticorrosion wellhead. Background technique [0002] Erosion is the combined effect of the surface of the metal material and the erosion of the corrosive fluid, causing local metal corrosion of the material. Generally speaking, the higher the velocity of the fluid, the more and harder the solid particles suspended in the fluid, and the faster the erosion and corrosion rate. At present, the flow rate of the wellhead is large, and a large amount of sediment will be mixed in the process of oil discharge. Due to the fast flow rate, the long-term erosion of the wellhead by the sediment will cause the wear of the wellhead. Once the wellhead is damaged, it will cause oil and gas leakage, which will not only cause Waste of resources and pollute the environment. Contents of the invention [0003] The object of the invention is to provide an anti-erosio...
