低渗油藏压力波传播规律及对产能影响研究

The propagation law of pressure wave in low permeability reservoir and its impact on production capacity

针对低渗油藏压力波传播规律,本文进行了数值模拟机理研究,直观表征了低渗透油藏压力波传播规律,并将压力波传播规律对产能的影响进行分析,分析认为低渗油井,产能将明显的越来越小,且不易于在产能测试获取稳定产能。研究对于建立产能评价方法,指导低渗油藏合理、高效的开采有着很现实的意义。

For the propagation law of pressure wave in low permeability reservoir.This paper has studied the mechanism of numerical simulation,which has directly expressed the propagation law of pressure wave in low permeability reservoir, and analysed its impact on the production capacity,the analysis thinks production capacity of low permeability oil wells will be significantly smaller and not easy to obtain stable productivity in production test.This study is significant for building the evaluation method of production capacity,guiding the reasonable and efficient exploitation of low permeability reservoir.
