| 摘 要： | 西峰油田长8油藏为特低渗岩性油藏。为了合理确定油井工作制度,通过实验分析研究了长8储层渗透率应力敏感、流体黏度、裂缝导流能力等因素随压力的变化特性,使用针对低渗透压裂井导出的产能预测模型,计算分析各参数对油井产能的影响规律,综合分析确定出该油藏最佳生产压差为5 MPa。 |
| 关 键 词： | 特低渗油藏 压裂井 产能 采油指数 |

| Abstract: | Chang 8 reservoir in Xifeng Oilfield belongs to ultra-low permeability reservoir.In order to make a reasonable working system,the change characteristics of permeability stress sensitivity,fluid viscosity and fracture conductivity as pressure are analyzed experimentally.Influence of reservoir parameters on well productivity is discussed by productivity prediction model in connection with low permeability fractured wells.The result shows that the optimal drawdown pressure for this reservoir is 5 MPa. |
| Keywords: | ultra-low permeability reservoir fractured well productivity productivity index |
