4、徏立井下压力^衡,防止地层体(Ҏ?不受控制地进入井?因ؓ地层体都有压力Q如果控制不好就是井喷了)M液密度主要用来控制后面两个?</p> <p> 甲酸N井液密度的作用体现在静液柱压力上Q简单地_密度大静液柱压力自然大Q对井壁和井底生的压力自然也就大。一杯密度ؓ1.0的清_和一杯密度ؓ1.2的溶?胶体Q重量当然是不同的。然后,地层都有三个压力Q坍塌压力、孔隙压力、破裂压力坍塌压力,压力于q个g塌了。孔隙压力,压力于q个值地层流体就q入井内了。破裂压力,压力大于q个g壁就被压漏了Q会发生井漏?</p> <p> 由此可以看出Q静液柱压力应该大于坍塌压力Q小于破裂压?ҎM方式不同Q可能大于或于孔隙压力。简单地_是不能让它压力太小而让井塌了,也不能让它太大而把井压漏了?</p> <p> 所以,M更要讲求安全环保Q甲酔RM液具有对地层损害、固相含量低pR惔饼博而韧q可酸化、井眼清z能力好Q抑制性强Q对环境污染,能增加聚合物的高温稳定性等优点Q是目前环保优质的钻井液抑制剂品?</p> </div> <div
