【判断题】
起管柱时不及时向井内灌修井液或灌量不足、快速起管柱情况最为危险。
【判断题】
有些地层是异常低压的，即其压力低于盐水柱压力。
【判断题】
井下作业时，修井液液柱压力的上限要保持与地层压力相平衡，即不污染地层，又能实现压力控制；而其下限则不能超过地层的破裂压力以免压裂地层造成井漏。
【判断题】
在一口井的各种作业中，始终有压力作用于井底，节流循环时，井底压力=静液柱压力+环形空间压力损失+井口回压。
【判断题】
泵压是克服循环系统中摩擦损失所需的压力。
【判断题】
修井液在环空中上返速度越大、井越深、井眼越不规则、环空间隙越小，且修井液密度、切力越高，则环空流动阻力越大；反之，则环空流动阻力越小。
【判断题】
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】
只要安装适当的地面装置，可以把气侵的修井液再重复循环到井内。
【判断题】
长期关井以后，由于天然气在井内上升而不能膨胀，井口压力不断上升。
【判断题】
尽管井内是正压差，仍有少量的天然气可以进入井筒。
【判断题】
排除天然气溢流时可保持循环罐液面不变。
【判断题】
从天然气侵入井内的方式来看，当井底压力大于地层压力时，天然气不会侵入井内。
【判断题】
气体侵入修井液与液体侵入修井液对修井液性能的影响相同。
【判断题】
在开井状态下，气柱滑脱上升越接近井口，修井液罐液面上升速度越快，溢流量才变得比较明显。
【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】
射孔过程中发生溢流时，应停止射孔，来不及起出射孔枪时，应剪断电缆，迅速关闭射孔闸门或防喷器。
【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。
【判断题】
及时发现溢流并迅速控制井口是防止井喷的关键。
