摘要
深井在实施压裂施工时,往往面临着地面施工压力高,设备承压有限,甚至压不开地层的情况。如何在现有施工设备条件下确保设备安全和施工成功成为亟待解决的问题。文章在分析压裂施工摩阻构成基础上,分别从降低管柱沿程摩阻、降低压裂液摩阻和裂缝缝内摩阻三个方面探讨了降低压裂施工摩阻的措施,并在现场进行了实施,施工后取得良好效果,为深井压裂提供借鉴。
The fracturing in the deep well often faced with high pressure of the ground construction, equipment with limited pressure, even pressure is not enough to open formations.It＇s the urgent problem how to ensure equipment safe and construction successful.This paper analyzed form of friction.Respectively from reducing friction along the string, friction of the fracturing fluid and friction inside the fracture, measures were studied.And implementation of these mesures achieved good results.It provided a reference for fracturing in the deep well.
