So, some countermeasures should be taken. New drilling technologies will be introduced including wash boring and micro -foam drilling. High-calcium salt polymer drill fluid with strong inhabit will be used in drilling, whose density should be adjusted according to the situation. Bore frame should be adjusted, that is to say, the pressure has few differences at one whole barefoot interval and density of the drill fluid should be big enough before drilling.

对此，提出如下治理对策：采用新的钻井工艺，引进清水强钻和微泡沫钻并技术；钻井中使用强抑制性高钙盐聚合物钻井液，并合理调整其密度大小；调整井身结构，在一个裸眼井段内不能有压力悬殊的地层存在，在揭开储层前，应适当提高钻井液密度。
