摘要
本文提出了 L ogistic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 L ogistic递减开发模型的影响。提出了开发初期 L ogistic递减开发模型的确定方法 ,便于开发初期决策。制作了 L ogistic递减开发模型的 log VD- log Rp图版 ,log VD- logat图版 ,log Rp- logat图版。提出了开发中晚期 L ogistic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。L ogistic递减开发模型是一种先慢后快的递减模型。
A mathematical expression for such development indexes as recovery rates and recovery percent of reserves is established on the basis of the logistic decline development model and the logistic decline development model is proposed. The effect of parameter on the logistic decline development model is analyzed. For the convenience of policy decision in the initial stage of development, the method of determining the logistic decline development model is proposed. Accordingly, the log logV D logR ptype curves, logV D～log(at) type curves and logRp^log(at) type curves are created. The proposition of assessment method and the matching methods for three point parabolic method and the three type curves for the logistic decline development model in the mid late stage development lies a foundation for the mid late stage prediction.
