| 摘 要： | 油田注水开发后地层压力的分布变化规律，对钻井作业和油田开发具有十分重要的意义。在对大庆油田注水开发后的异常地层压力成因和分布特征进行研究后，指出油田注水后层内、平面和层间三大矛盾的加剧是异常地层压力形成的主要原因，在纵向上高压层、欠压层和正常压力层相间存在构成典型的多压力层系剖面，在平面上形成异常欠压区和异常高压区，根据异常地层压力的成因和分布特征，可以划分出10种类型的异常高压区。

| Abstract: | The distribution variation law of formation pressure after water flooding in oilfield possesses very important theoretical meaning and real meaning to the well drilling operation and oilfield development.This paper studies the cause and the distribution characteristics of abnormal formation pressure after water flooding in Daqing Oilfield.It proposes the major reason that three main contradictions between inner,areal and interlayers form the abnormal formation pressure.The abnormal under pressure area and the abnormal high pressure area form in plane. According to the cause and distribution characteristics of abnormal formation pressure,it can be divided into 10 types of abnormal high-pressure areas. |
