摘要
研究发现,对于产量处于上升阶段的油气藏,传统的预测模型并不能很好反映其产量变化趋势。以Logistic微分方程为基础,利用现场资料数理统计,提出Logistic产量预测新模型。该模型避免了累积产量对时间的求导,能更直观的反映产量变化情况。通过西部某油藏的实际应用表明,该模型对产量的预测是可行的。
It is found by study that traditional forecasting model is not use ful for reserv oir that is in ascent state. Basing on the logistic differential equation, and u sing mathematical statistics of field document, then we proposing the new logist ic model of production forecast. This model avoids the derivation of cumulative production to time, and it can reflect production history more illustrative. App lying this model to a western reservoir, and the result means that the model is feasible.
