Abstract: Marginal small gas fields have the characteristics of small reserves,high development difficulty and poor economic benefits. In order to adopt the non-submarine cable power supply scheme,the platform equipment selection optimization is carried out to reduce the power consumption and system scale to the greatest extent. At the same time,the possibility of new energy power supply methods,namely solar or wind power generation solution is explored. In the end,the overall platform design is simplified,the project investment is reduced,and a new idea is provided for the subsequent development of marginal small gas fields.

Key words: marginal small gas field, new energy power supply, control system
