THE DISCUSSION ABOUT HOW TO OBTAIN THE KEY PARAMETERS OF GENERALIZED PARETO DISTRIBUTION

Generalized Pareto is an important method of resource assessment,this method is widely used in forecasting the total quantitative and structure of resource by calculating the number and scale of reservoir.How to obtain four key parameters is important in this method:q₀(minimum pool size)、q_max(maximum pool size)、r(median oil and gas pool size)、λ(distribution parameter).For low degree of exploration areas,because resource abundance and the maximum reservoir size uncertain,the key parameter is difficult ascertain by the conventional method.According to this,auther discussed how to obtain the four key parameters and deduced the formula,this is important to further application of this method.
