| 摘 要： | 在钻井参数优选设计中,钻井液流变参数的优选要满足井眼安全的三个约束条件,根据这三个约束条件可以确定出流量的数值范围。以幂律流变模型为例推导出最低排量和最高排量的计算公式。当钻速在一定范围之内变化时,满足环空岩屑浓度约束条件的最低排量随钻速增加而增加,由此推导出最低排量随钻压变化的计算公式。

| Abstract: | In drilling parameter optimization design,it will meet three constraint conditions of borehole safety.According to these three conditions,the scope the discharge can be made.Setting power rule rheological module as an example,the computational formula of minimum discharge and maximum can be got.When the drilling speed changes within the scope,the minimum which meets the constraint condition will increase which the speed increases,so as to get the formula of it. |
