所谓井底压差就是地层压力与井底压力之差。
【判断题】
合理的修井液密度应该略大于（平衡）地层压力，大于漏失压力，而小于坍塌压力、破裂压力。
【判断题】
某井正常正循环时，井底压力＝静液柱压力＋环空压力损失。
【判断题】
当井浸发生后出口返出的液量比泵入的液量多，停泵后井口修井液自动外溢，这种现象就称为井涌。
【判断题】

【判断题】
发生气体溢流必须长时间关井，避免发生气体上窜。
【判断题】
天然气只有在开井的条件下才可能发生滑脱上升
【判断题】
长期关井以后，天然气在井内上升而不膨胀，井口压力不断上升，相应的表明地层压力也非常高。
【判断题】
溢流关井后，关井油、套压上升越快，说明了地层压力增加也越快。

【判断题】
起管柱速度越快，产生抽吸压力也越大，引起井内修井液密度下降越多。
【判断题】
停止循环后，井口修井液仍不断地外溢，说明已经发生了溢流。

及时发现溢流并迅速控制井口是防止井喷的关键。
【判断题】
若能尽早地发现溢流，则硬关井产生的“水击效应”就较弱，也可以使用硬关井。
【判断题】
关井后要及时组织压井，如果是天然气溢流，可允许长时间关井而不作处理。
【判断题】
软关井的优点是关井过程中，防止水击效应作用于井口装置，可试关井。
