Abstract: Because of the differences in technical requirements, such as geologic oil reservoirs, wellhead platform conditions and logic control, the control principle and working method of the wellhead control panel are different, which lead to the basic design of the product. In order to summarize the product type and The design features of the wellhead make up the shortage of this research direction, and provide reference for the design and selection of the wellhead control panel. The design type analysis of the wellhead control panel is needed. According to the characteristics of the components and the environment, the design features of each type of control panel are summed up and summarized, and the design scheme of the wellhead control panel is described in detail and contrasted. Electronic push-button type is divided into positive pressure explosion-proof type and flameproof type, mechanical pilot valve type according to the different platform design requirements, divided into two types of control panel, Hydraulic control and gas-liquid control, and the characteristics of each type of design and application are analyzed. The cost and maintenance cost of the mechanical pilot valve control panel is low. Taking DCS as the control core, the design is the mainstream trend. It is recommended to use it in view of cost and maintainability.
