摘要
七棵树油田属于低孔特低渗的构造岩性油藏,天然能量以弹性能量为主,试油试采结果表明,油藏的天然能量不足。自开发以来,地层累计亏空严重,地层压力亏空大,为了保证复产后能量充足,应在关停期间加强注水,提高地层压力。
The qishu oilfield is a low-porosity and ultra-low permeability tectonic lithologic reservoir.The natural energy is mainly elastic energy.The test oil test results show that the natural energy of the reservoir is insufficient.Since the development,the accumulated deficits in the stratum have been severe,and the formation pressure has a large deficit.In order to ensure sufficient energy after the resumption of production,water injection is strengthened during the shutdown period to increase the formation pressure.
