| Abstract: | A mathematical expression for such development indexes as recovery rates and recovery percent of reserve is established on the basis of the FWG2 decline development model.The effect of parameter on the FWG2 decline development model is analysed.For the convenience of policy decision in the intial stage of development,the method of determining the FWG2 decline development model is proposed.Accordingly,the logV D logR p type curves,logV D log(at) type curves and logR p log(at) type curves for the FWG2 decline development model are presented.The proposition of assessment method and the matching method for three point parabolic method and the three type curves for the FWG2 decline development model in the mid late stage development lies a foundation for the mid late stage prediction. |
