摘要
HDR29D地热井施工中发生了粘吸卡钻事故,给钻井施工带来了困难。经过分析卡钻原因、研究解卡方案,配制了解卡剂,解决了棘手的粘卡问题。根据该井的实际情况,对定向井粘吸卡钻事故原因、处理方法进行分析总结。
Drilling pipe sticking accident occurred in HDR29D geothermal well,which was overcome by the accident cause analysis,stuck-releasing scheme study and stuck-pipe freeing agent compounding.The paper summed up the causes of drilling pipe sticking in directional well and the treatment method.
