摘要
JY-1井位于山西碛口锦源煤矿,设计为一水文勘探孔兼做水源井。在钻井施工进入奥陶系时,发现井内涌水,并伴有H2S气体,实测含量为20μg/g。为治理该井,首先进行了物探测井,然后制订了压、堵、封的治理方案,同时对治理过程进行了较为详细的介绍。治理结果表明,井中水位静止,井口H2S含量为0,说明治理获得了成功。最后对该类型井的治理提出了建议。
The well JY-1 in the Jinyuan coalmine,Qikou Town,Shanxi Province is a hydrogeological exploration borehole doubled as a source well.When the well drilling into Ordovician,water gushing had happened and accompanied H2S with measured content 20μg/g.To harness the well,carried out geophysical well logging first,then pressing,stopping and sealing scheme formulated and also the paper introduced the harness process in detail.The result has demonstrated that the water table in well is static,zero H2S content at the collar,thus the harness succeeded.Finally suggestions put forward for harness of same type wells.
