【摘要】 在紊流流态下,因受水平钻井条件和钻井液水力参数、流动特性的影响,水平段岩屑运移方式有所不同。简单介绍了水平井偏心环空岩屑运移模型,在此基础上引入了判别井下岩屑床清除效果的一种简化模式,讨论了模式计算与现场监测方法的一致性,两者结合能较好地满足清除水平井岩屑床的现场需要。更多还原

【Abstract】 :The removal of drill cuttings in horizontal section is different from that in the vertical section. The model of cuttings moving in horizontal eccentric annulus is presented , and a model to predict the result of the removal of cuttings bed in horizontal section is also given .更多还原
