| 摘 要： | 通过对文东油田文203断块储层岩石的压力敏感性伤害程度的研究，认为在油藏投产后，随地层流体的采出，地层孔隙压力逐渐降低，储层上覆有效压力增大，导致储层渗透率有较大的降低，影响了深层低渗储层油田注水开发的效果，提早注水和保持压力开采是防止压力敏感性伤害，保持储层渗流能力的主要方法。

| Abstract: | According to the research of the degree of rock injury to pressure sensitivity in block Wen203,Wendong oil field, the article considered that formation pore pressure relief and overlying effective pressure increment with the production of fluid after putting into production of reservoirresulted in remarkable reduce of reservoirpermeability and influenced the water injection response in deep seated and low permeable reservoir, so water injection ahead of time and keeping pressure production were the primary way avoiding to pressure sensitivity injury and keeping percolation ability of reservoir. |
