| 摘 要： | 为了对榆林气田山2气藏的气井生产动态进行预测.建立了适合于定容气藏的具有补给作用的物质平衡模型,它考虑了由于气藏开采中高产区与低产区之间压力差异导致的气量补给.利用建立的数学模型对榆林气田南区的气井进行了生产动态预测的研究.结果表明:模型可以预测气井在稳产期和递减期的地层压力、井底压力及气井产量、采收率等参数随时间的变化规律,以及气井在不同配产下的稳产时间.利用该模型可以据此对气田开发方案进行调整,对于气田的有效开发具有重大意义.

| Abstract: | In order to predict the production performance of gas wells in Yulin gas field,a new mathematical model with supplementation is proposed in this paper for predicting the production performance of a closed gas reservoir. The model accounts for the recharge between high production and low production zones caused by gas's heterogeneity and differences in pressure. A case study is conducted to predict the production performance of gas wells in southern areas of Yulin gas field. The results show that the model c... |
