摘要
将井下钻井液、地层、水泥环、套管、钻柱等中的流动和传热组合起来 ,作为一个统一的过程来进行求解 ,从而避免了不同区域间的反复迭代 ,有利于井下复杂的井身结构和钻柱组合的处理。数值模拟结果和现场测量数据的对比初步说明该方法是可行的。
The flow and heat transfer in downhole drilling fluid, formation, cement sheath, casing string and drilling string are combined and solved as a unified procedure. Thereby the repeated iteration among different regions is avoided and the complicated casing program and drilling string assembly are treated easily. The comparison of predictions with field measured data shows preliminarily that the method is feasible.
