摘　　要：在钻井施工作业中,井漏严重影响着钻井速度、建井质量和效益,是钻井工程的头号隐患。井漏是最为常见的事故之一,一旦发生井漏会降低钻井速度,增加钻井成本。本文给出有关井漏的预防及处理措施,并以涪陵地区龙马溪组几口代表井为例给出有关处理措施在该地区的应用。最终得出结论,该地区对于非失返性可采用常规方法控制钻井液密度及随钻封堵进行防漏堵漏,对于失返性漏失采用复配复合桥接浆堵漏具有良好的效果。Lost circulation in drilling construction work serious influence the speed, quality and etficiency, It＇s the top of hidden troubles. Lost circulation is one of the common accident, once lost circulation happen can reduce the speed of drilling and increasing drilling cost. Several representative wells about formation of LongMa in FuLing area as an example and given the application of prevention and treatment measures in this region. Eventually come to conclusion, for no loss return, could use conventional methods to control density of drilling fluid and plugging while drilling, for loss return could use bridged hybrid mud with composite materials to plugging and obtaining good results.
