泉子街地区地层可钻性分析及钻头选型
|
摘要
泉子街地区页岩气参数井钻进过程中存在地层可钻性差、研磨性较强,钻进速度慢,单只钻头(牙轮、PDC)进尺少且报废率高等问题。本文通过对泉子街区块岩石可钻性进行分析、评价,可以为该区页岩气勘查钻井施工钻头选型和钻井工程设计优化提供依据,从而达到提高该区钻井施工效率、降低钻井成本、缩短项目工作周期的目的。
During drilling of shale gas parameter wells in the block of Quanzijie area,there were some problems such as poor formation drillability,strong abrasiveness,slow drilling rate,less footage per drill bit(cone,PDC)and high abandonment rate.Through the analysis and evaluation of the rock drillability of the Quanzijie block,this paper provides the basis for shale gas exploration drilling bit selection and the optimization of the drilling design in this area so as to achieve the purpose of improving drilling efficiency,reducing drilling cost and shortening the construction duration.
