| 摘 要： | 依据油水两相渗流理论和对流扩散理论,进行泥浆侵入三维数值模拟.考察泥浆侵入对大斜度井/水平井测井环境的影响.大斜度井/水平井泥浆侵入受各向异性的影响,井周岩石物理失去轴对称分布特征,但一般重力影响相对较弱;采用三维有限元方法.进行不同井斜条件下海水泥浆侵入双侧向测井响应数值模拟,深浅侧向电阻率受相对井斜的影响,且随井斜角增大,无泥浆侵入的非厚储层其深浅侧向电阻率呈现负差异;随海水泥浆侵入影响加深,不同井斜情况的深浅侧向视电阻率幅度差异变化呈现复杂特征,且井斜角越大,深浅电阻率正差异出现得越晚;水平井相对于直井来说,双侧向测井响应与层厚及嗣岩校正关系差异很大.

| Abstract: | The log environment in high deviated well and horizontal well is complex due to the relative borehole deviation,formation thickness and mud invasion.Based on the theories of oil-water two-phase fluid flow and water convective diffusion,the dynamic brine mud filtrate invasion of reservoir in such well was three-dimensionally and numerically simulated,which shows that petrophysics of the reservoir around borehole is not axisymmetrical due to the permeability anisotropy of the reservoir in the high deviated an... |
