摘要
利用先进的大型仪器—岩心驱替装置模拟吐哈油田7个区块地层渗透率随覆压变化的过程,找出了其解析式,通过解析式分析可总结出地层压力下降及恢复过程中油井产能和注水井注入能力变化规律,因而为采取合理的采油制度,保持油井产能提供重要的依据。
The process of stratigraphic permeability followed overburden-pressure variation of 7 blocks was simulated by using the large advanced instrument-core displacement install and found out its analytic formula.Through analysing the analytic formula the variational law of well production capacity and water well injectability had obtained in process of stratigraphic pressure falling and build-up.It provided important basis for system of rational oil production and keeping oil well production capacity.
