| 摘 要： | 假定钻头具有侧向切削性能和地层正交各向异性,导出了三维情形下的钻头—地层相互作用模式,建立了定向钻井的三维计算机模式。模式中输入钻具组合结构、地层特性、钻井参数和井眼状况等数据后,可模拟计算出三维井眼轨迹。对多口井进行了模拟计算,将其结果和实钻结果做了比较,两者的吻合程度较好,证明了模式的可靠性。

| Abstract: | The three-dimensional bit-formation interaction model wasderived by assuming that the bit has of lateral cutting ability'and the formation is orthogonally anisotropic. A computer model for directional drilling was developed with input data of BHA structure, drilling paramers, formation characteristics and so on. A three-dimensional simulated wellbore trajectory was produced. The comparison of computation results by this model with the actual paths of the directional wells showed a good agreement. |
