摘要
运用R/S分析的基本原理和方法,对四川新场气田20余口产量递减井分别进行了Hurst指数计算,计算值均大于0.5,说明气井的产气量变化具有明显趋势性成分,并且这种趋势性成分均表现为持续性。引用GM(1,1)灰色模型对气井的产量进行拟合,并在此基础上进行了产量预测。结果表明该模型是可靠的,实用的,可行的。
The Hurst indexes of more than twenty production declining wells in Xinchang gas field are calculated by the fundamental principle and method of the R/S analysis, and all the Hurst indexes are greater than 0. 5. This shows that the change of the production of the gas wells has the obvious persistent trend. At last, GM（1,1） grey model is used for fitting and to predict the production of the gas wells. This model is proved to be effective, practical and believable.
