| 摘 要： | 平湖油气田位于东海陆架盆地西湖凹陷保俶斜坡平湖构造带中段,主要生产层是渐新世花港组油藏和始新世平湖组气藏。传统地质观点认为平湖组为主要气藏,但是实际生产中八角亭BX1井平湖组P11等气层有原油产出,给油气藏的开发带来一定挑战。准确地确定储层的流体性质,不仅对气藏开发方式选择和开发经济政策制定,而且对滚动勘探都具有重要意义。根据气、油和水物理性质之间的差异,利用非电测井信息,基于不同饱和流体岩石具有不同的横波时差、纵波时差、纵波等效弹性模量、流体密度、流体时差和流体声阻抗,结合其它测井手段,有效识别了平湖油气田AX9井、BX8井、BX1井和PX9井储层的流体性质。识别结果与实际生产状况基本一致,说明该方法在平湖油气田流体识别方面具有良好的应用效果。

| Abstract: | Pinghu oil and gas fields are located in the middle slope of Xihu Trough,the East China Sea Shelf Basin,with the pay zones of Huagang formation for oil and Pinghu formation for condensate gas.Oil production in Pinghu formation brings difficulty to oilfield development as Pinghu formation was thought as the main gas reservoir,so the identification of fluids plays an important role in oilfield development which not only influences the selection of development program but also influences rolling exploration.Ro... |
