Abstract: The characteristics of high investment and high risk in oil-gas productivity investment projects were discussed.A mathematical model,taking income and risk as optimization target under the multiple restriction conditions was built.A mixed genetic algorithm based on multi-target optimum solution was presented.This algorithm could solve the mathematical model effectively by presenting its solution front.Application case shows that this model and its solving method are easily operated and can provide decision basis in the fields of risk and income for oil-gas productivity investment projects.

Key words: oil-gas production, productivity investment, project income-risk objective optimization model, mixed genetic algorithm, optimization solution
