摘要: 综合成藏地质学、岩石力学和渗流力学,建立准确可靠的致密油藏考虑边界层、临界喉道和孔喉分布的液测应力敏感性计算模型.由于大庆油田致密油藏孔喉分布范围比长庆油田更窄,导致大庆油田应力敏感性更强,因此大庆油田产能更低.本文从微观角度定量表征了真实油藏中应力敏感性的作用机理.

关键词: 致密油藏, 边界层, 应力敏感性, 孔喉分布

Abstract: A model to calculate stress sensitivity is established based on theory of accumulation of geology, geomechanics and theory of flow through porous media. Compared with experimental results, the model is accurate and reliable. Distribution range of tight oil reservoir in Daqing Field is narrower than that of Changqing Field. It results in that stress sensitivity of Daqing Field is severer than that of Chaingqing Field. And productivity of Daqing Field is lower than that of Changqing Field. We make a quantitative description on mechanism of stress sensitivity in tight oil reservoirs.

Key words: tight oil reservoir, boundary layer, stress sensitivity, pore-throat distribution
