摘要
在尼日尔三角洲盆地中,超压层是深井钻探作业中不可避免的一种地质现象,若预防措施不当,就有可能发生井涌(喷)、卡钻,导致井报废等。因此,预防超压层是钻井工程中最令人关注的事情之一。超压层的预测方法较多,本研究主要以尼日尔三角洲盆地两口井为例,介绍怎样利用泥浆出口温度在随钻跟踪分析中预测超压层。
Overpressure zone was an inevitable geological phenomenon of deep well drilling in Niger Delta Basin,if preventive measures were not proper,it would result in well kick(blowout) and drill-pipe sticking,as a result,it would cause well abandonment,etc.Therefore,preventing overpressure zone is one of the most attentive jobs in drilling engineering.There exist methods for forecasting overpressure zones.In this paper,two wells are taken in Niger Delta Basin for examples to describe how to use the outlet mud temperature to forecast overpressure zone in drilling analysis.
