摘要
通过对油气田大量生产数据的统计分析，发现油气田产量与累积产量平方的比值和开发时间存在着相当好的半对数直线关系。基于这个规律，推导建立了油气田产量、累积产量、可采储量、最高年产量及其发生时间的预测模型，阐述了参数的估计方法，并与其它模型的预测结果作了对比。结果表明，文中提出的预测模型是可靠、有效的。
It is found that the relationship between ln (Q/Np2) and t is linear by analyzing amounts of producing data of oil-gas fields. Based on the regularity, the paper presents a method for forecasting production, cumulative production, recoverable reserves, production peak and its corresponding time of oil-gas fields. The method for solving the model is given and compared with the results given by the existing forecast model. Two examples to illustrate this method are given.
