摘要
TS3CX井是塔河油田奥陶系油藏一口一开制侧钻斜井,该井在目的层奥陶系鹰山组钻进施工过程中遭遇先漏后涌、钻遇大段放空段的复杂情况,且钻遇具有定容特点的储集体,导致井内压力平衡难以实现,对井控安全和定向钻进极为不利,填塞侧钻是最为经济有效的解决办法,但该井实现一次性成功打水泥塞的难度极大。通过"悬空水泥塞"技术实现了该井一次性打水泥塞成功,对工区内类似井发生相似情况的处置提供了宝贵的经验。
Well ts3cx is a sidetracking deviated well in Ordovician reservoir of Tahe oilfield,During the drilling operation of the target formation of Ordovician Yingshan formation,the well encountered the complex situation of first leakage and then kick,and large section of vent section,In addition,it is difficult to realize the pressure balance in the well due to the reservoir with constant volume,It is very unfavorable to the safety of well control and directional drilling,and sidetracking is the most economical and effective solution,However,it is very difficult to achieve one-time successful cement plug in this well.However,it is very difficult to achieve one-time successful cement plug in this well.It provides valuable experience for similar wells in the work area.
