| 摘 要： | 基于千户营煤炭勘察区地层造斜严重、井内坍塌、井径扩大严重等问题,采取了更换泥浆体系以及水泥封固等措施,顺利完成钻探工作。通过对钻效分析与测井曲线对照在破碎坍塌井段得到印证。施工中所应用钻探工艺为类似工程提供一定的借鉴。

| Abstract: | Based on serious stratum deformation, borehole collapse, hole diameter enlargement in Qianhuying Mine exploration area, replacing the mud system and cement cementing measures were adopted to complete drilling work. Through drilling effect analysis and well logging curve comparison got the confirm in the crushing collapse interval. The drilhng technology in the construction provided reference for the similar project. |
