裂缝监测技术在塔河油田的应用

Application of fracture detect technology to Tahe oil field

    摘要
  • 摘要: 塔里木盆地塔河油田奥陶系油藏80%以上的井直接完井后无自然产能或自然产能低,需要通过酸压改造沟通缝洞储集体后才能建产。但塔河油田储集体分布非均质性极强,且分布方向与地应力方向并不完全一致。酸压设计规模主要参考地震资料预测储集体离井筒的距离,通过地面检波器接收地层破裂时的微地震波信号来监测酸压裂缝方向、酸压裂缝长度、裂缝产状,改造地层现今主应力方向,为酸压改造效果评价,进一步优化酸压设计提供依据。现场实践证明,塔河油田酸压裂缝监测技术基本克服了井深的不利条件,成功监测了超深井大型酸化压裂时裂缝走向、裂缝长度及产状,基本满足了超深井储层改造监测要求。

     

    Abstract: In view of low natural productivity and great anistotropy characteristics of Tahe oilfield,and acid fracturing design is based on seismic data.Detect fracture orientation,fracture length and fracture attitude from micro-seismic signal received by surface geophone.It can reform orientation of current crustal stress,provide foundation for fracturing effectiveness and acid fracturing design.Field experiment shows that this technology can effectively detect fracture orientation,length and attitude,and can overcome affect of well depth.
