摘要
PY气田A03H井是一口大位移套管开窗侧钻井,该井开窗侧钻点深、摩阻大、斜向器座挂难度大,斜向器本身狗腿大影响旋转导向工具稳定性。从开窗侧钻点选择、开窗侧钻施工等方面介绍了套管开窗侧钻技术在PY气田大位移井中的应用情况。该井定向开窗侧钻的成功对该区块深井侧钻施工、降低作业成本有重要的参考价值。
The Well A03H of PY Gas Field is a large displacement gas well drilled by casing sidetracking,which has the properties of deep side windows drilling point,serious friction,the problem of hanging the whipstock and the stability of rotary steerable tools impacted by whipstock's inherent big dogleg.This article introduces the application of sidetracking technology in large displacement gas wells in PY Gas Field from selection of the window sidetrack point,construction of the window sidetrack the of.The success of sidetracking of directional drilling of the well provides important reference for deep well sidetracking are reducing operation cost in the area.
