Problems solved by technology
[0003] 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 apparatus, and is specifically a anti-corrosion wellhead. Background technique [0002] Erosion is the combination of the surface of the metal material and the corrosion fluid flushing, but causes metal corrosion of the material. In general, the solest fluid is higher, and the mixed solid particles in the fluid is more harder, the faster, the faster, the detergent. [0003] At present, the flow of well ports is large, and a large number of sediments will be mixed during the oil reservoir. Due to the fast flow rate, the long-term erosion of the sediment will cause the wear of the wellhead. Once the wellhead will cause oil and gas, not only causes Resource waste and will pollute the environment. Inventive content [0004] It is an object of the invention to provide an anti-eroding anti-corrosion wellhead to solve the problems raised in the above background. [0005] In order to achieve the above object...
