摘要
本文以约翰西克等人提出的摩擦阻力综合参数模式为基础,考虑了钻柱拉力与钻柱所受侧向力具有相关性这一因素,建立了更符合实际情况的摩擦阻力模式,根据此模式结合大庆油田中区所钻定向井的实际情况,对其摩擦系数值进行了初步确定,并对巳知泥浆性能、钻具组合和井斜资料的定向井进行了摩阻拉力和转矩损失的预测分析。
The paper is based on the frictional drag model presented by Johancisket al. Considering the factor that the drillstring tension is related to theside forces of the drillstring, we have established a more suitable fric-tional drag model. According to this model, and the actual conditions of thedirectional wells drilled in the middle zone of Daqing oilfield, we preli-minarily determined the friction coefficient. In addition, we analysed thedrill string tensions, frictional drags and torque losses for the direc-tional wells in which mud properties, drillstring con-figurations andwell deviation data had been obtained.
