摘要
介绍了页岩气基础地质调查项目湘洞地1井的工程概况,重点阐述了该井的钻探施工技术与工艺;结合实钻地层及测井数据对钻井施工质量进行了总结分析;针对钻进过程中出现的问题,提出了改进措施,取得了显著的实钻效果。湘洞地1井采用金刚石绳索取心钻进工艺,通过预判该工艺及强造斜地层的常见事故,优选施工方案,中期严控施工质量,有效预防井内事故的发生,提高了钻进台月效率;钻孔质量六项指标均满足地质要求,顺利有效地完成了钻井施工任务。
The paper introduces the general situation of Well Xiangdongdi 1 for basic geological survey of shale gas,describes emphatically the drilling construction techniques and process.Combined with the actual drilling strata and well logging data,the drilling construction quality is analyzed and summarized.In view of the problems in the drilling process,the improvement measures are put forward and remarkable effects have been achieved.Diamond wire-line core drilling technology is adopted in Well Xiangdongdi 1,by the prediction of common accidents in this technology and strong whipstocking stratum,construction methods are optimized and mid-term construction quality is strictly controlled to effectively prevent downhole accidents and improve the driller-month efficiency.6 indicators of drilling quality meet the geological requirements,drilling construction is smoothly completed.
