| 摘 要： | 井眼钻成后，由于岩石的蠕变而常发生井眼缩径，使钻具、套管和测井仪器难以下到井底，本文应用粘弱性理论，对横观各向同性岩层井眼的位移进行了分析，推导出井眼径向位移与原地应力、岩层的各向异性特性、稳定周期及钻井液密度的关系式，本文的分析和给出的计算公式对在横观各向同性岩层钻井设计和施工具有一定的指导意义。

| Abstract: | Because the well size shrink caused by rock creeping,the drill stem,casing and log instrument can't be run into the bottomof the hole freely.The analysis of the rock stress and displacement of the surrounding wellbore of the traversely isotropic rock ispresented.The relation formula of the radial displacement,earth stress,anisotropy,stabilizing and fluid dendity is derived with thetheory of rheology,The conclusions have guiding singificance for the well design and drilling operation. |
