摘要
建立产量预测模型,对研究区产量进行预测和分析。对比各种方法在油气田不同开发阶段的预测精度,指出GM(1,2)模型对预测产量的单调上升或单调下降较为准确,而其他模型则可用于对油田开发指标的全程预测。
The low permeability gas reservoir,which is controlled by depositional environment,is characterized as low permeability and bad connectivity between sand bodies,associated with big resistance of fluid.The petroleum product pattern for the low permeability reservoir is different from normal permeability reservoir,causing the difficult prediction of petroleum production.GM(1,2) grey model,GM(1,1) grey model and the decline characteristics of Arps model are used to analyze the gas well in the low permeability gas field.Compared with the result of the actual measurements,GM(1,2) grey model is effective with a higher degree of precision and guide significance for setting up production programs.
