摘要
在某些简化及假设的前提下,建立了三牙轮钻头井底平面流场物理模型,并进行了实验验证.实验结果表明.井底平面流场服从所建立的物理模型.从而为井底流场的计算机模拟奠定了基础.
A physical model for the bottomhole crossflow hydraulics of tricone roller bits was developed under certain simplifications and hypotheses. Some tests was made in laboratory. The experimental reuslts showed that the bottomhole crossflow hydraulics can be expressed with this physical model. The model provides the foundation for the computational modeling for the bottomhole crossflow hydraulics.
