摘要
提出了定向钻井计算机模式的基本原理,推导了二维情况下的钻头—地层相互作用模式,从而建立了定向钻井的二维计算机模式。该模式输入钻具组合结构、地层、钻井参数、井眼状况等数据,输出二维井眼轨迹曲线。对模式的计算结果和实钻结果作了比较,两者的吻合程度是令人满意的。该模式的特点是计算时间少,可在微机上运行,现场使用方便。
The basic principle of computer model of directional drilling is presented. The two-dimensional bitformation interaction is derived, and a 2-D computer model of directional drilling is set up. The model inputs data such as BHA structure, formation characteristics, drilling parameters and wellbore conditions, and finally outputs a simulated wellbore trajectory. This model is characterized by less computer time and operation on microcomputer, thus facilitating field use.
