SUMMARY A more accurate steady drillstring tension-torque model has been established by taking into account of drillstring, wellbore condition , drilling operation and drilling parameters. This model has been used in scientific calculations of directional and horizontal wells, such as determing the friction factor between wellbore and drillstring, calculating the hook load and rotating torque, ckecking the strength and stability of drillstring, optimizing well trajectory, computing the WOB while drilling by downhole motor and predioting the maxinum allowable length of horizontal section.

综合考虑钻柱、井眼环境、作业过程和作业参数的影响，建立了更完善的钻柱稳态拉力和扭矩模型，并将其应用于确定钻柱与井壁的摩擦系数、计算大钩负荷和转盘扭矩、校核钻柱的强度和稳定性、优选井眼剖面、推算井下动力钻进的实际钻压和预测水平井段的最大可钻长度等定向水平井的科学计算中。

Finally, we present an arithmetic of multiplehypocentral, heterogenous dislocation, and a multirupture segment superposition model for simulating the earthquake deformation field. The simulated LOS interferometry map presents the distribution characteristics of the earthquake deformation field better than that of previous studied. Meanwhile, a suit of fault geometric parameters of the earthquake is also obtained by the study. Having a better effect upon simulating asymmetry, great dislocation, macro rupture field, and nonhomogeneity of dislocation than the traditional model, the multisegment method is a progress of this work. It provides a better explanation for the study on hypocentral parameters.

基于上述原因，本文对Okada线弹性位错模型的算法进行了改进，提出了&多震源、非均一位错分量、多破裂段叠加&的线弹性模型，该模型模拟出的形变场干涉纹图较好地体现了地震形变场的分布特征，并由此获得了一套较为完整的地震发震断层的几何学特征参数，为破裂带长度、破裂面方向、破裂面大小等震源破裂特征参数研究提供了较好的解释。
