摘要
本文提出了 FWG2递减开发模型 ,提出了开发速度 ,采出程度等开发指标的数学关系式。分析了参数对 FWG2递减开发模型的影响。提出了开发初期 FWG2递减开发模型的确定方法 ,便于开发初期决策。制作了 FWG2递减开发模型的 log VD- log Rp 图版 ,log VD～ log(at)图版 ,log Rp- log(at)图版。提出了开发中晚期 FWG2递减开发模型的判断方法 ,三点抛物线法和三种图版匹配的拟合方法 ,为开发中晚期预测奠定了基础。 FWG2递减开发模型是一种高精度直线递减模型。
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.
