中文摘要:冀中地区第三系地层以紫红泥岩、灰色细砂岩为主，泥岩造浆能力较强，有些地区地层很不稳定，给钻井施工带来难度，特别是水平井施工工艺复杂，极易发生卡钻事故，一旦发生卡钻事故，处理不好，损失巨大。通过一口水平井事故的发生、事故成功解除为例，总结出水平井施工过程中的复杂事故预防措施，对该地区及其它地区水平井施工提供一些借鉴。

Treatment Practice for Sticking Failure in Horizontal Well and Discussion on the Prevention Measures
Abstract:Teriary strutum in Central Hebei is mainly of purplish red mudstone and fine grey sandstone with strong mudstone mud making, some formations are very unstable, which make drilling construction difficult with drill bolcking. The paper summed up the prevention measures for complicated accident in horizontal well construction with a successful treatment case, which could be the reference to horizontal well construction in Central Hebei district and other places.
