摘　　要：岩石应力敏感和启动压力梯度是特低渗透油藏开发的重要影响因素，为了有效开发具有启动压力梯度和应力敏感的特低渗油藏，本文从特低渗透油藏渗流机理出发，结合岩心室内实验研究结果，建立了长庆特低渗透油藏考虑应力敏感和启动压力梯度的渗流模型，研究了特低渗油藏合理生产流压确定方法，现场应用效果较好。In order to effectively develop uhra-low permeability reservoirs with a start-up pressure gradient and stress-sensitiveness, proceeding from the percolation mechanism of uhra-low permeability reservoirs,combining with core laboratory＇s findings, a percolation model of Changqing ultra-low permeability reservoirs was established in this article, taking into account the stress-sensitiveness and start-up pressure gradient. A reasonable flowing pressure on the production of ultra-low permeability reservoirs is studied, with a good effect at the scene.
