摘要
利用流体力学的基本原理,研究筛网表面钻井液的流动特点.在综合筛箱运动、筛网倾角等参数对筛分影响的基础上,建立钻井筛的筛分模型,给出处理量的计算公式.探讨了运用均能原理和有限差分方法对筛分方程的求解,并编写处理量的数值计算程序.室内台架模拟试验结果表明,建立的筛分模型具有较高的计算精度.
Based on the basic principle of hydromechanics, the flow characteristic of drilling fluid on the screen was studied. By taking the consideration of various parameters affecting the screening effects, such as vibration and screen angle, a screening model for a drilling fluid shale shaker was established. The screening equations were solved by average energy principle and finite differential method, and the treating capacity of a shaker was calculated numerically. The comparison between the results of calculation and indoor simulation rig test shows that the screening model is of high accuracy.
