摘要： 提出了一种用于预测油田开发指标的新型准广义增长曲线——bttc因子型增长曲线。研究表明,其对应峰值产量的累积产量与最大可采储量之比变化范围为0~1.0;在直角坐标上,Qt—Np,关系的最后段可以同时反映它们向上凹和向下凹两种情况; Np—t和Qt—t关系都有解析式。提出了求取这种增长曲线的参数的重复二元回归法。庆祖集油田的计算实例表明这种增长曲线有较大的使用价值。

Abstract: bttc factor growth curve, a new kind of quasi-generalized growth curve,which can be used to predict indexes of oilfield development,was proposed. The studies show that the ratio of cumulative production and maximum recoverable reserves corresponding to maximum production is ranged from 0 to 1.0 for this growth curve. The end section of the relationship of Qt vs. Np, can be concave upward or downward, and the relationship of both Qt vs.t and Np vs.t has the analytical expression respectively. The repeated duality regression method obtaining the parameters of this growth curve was presented. An example from Qingzuji oilfield shows that this growth curve has a greater value for application.
