| 摘 要： | 针对四川气田部分地区泥页岩易坍塌而造成卡钻事故的情况,在对国内外各种预测井眼稳定性方法进行验证评价优选后,本文从力学角度入手,建立了适当该地区的井壁稳定力学模型,通过分析测井资料与计算井壁稳定性所需的岩石各弹性参数间的关系,研究如何利用测井资料来计算预测井壁稳定条件的工作。利用编制的井壁稳定性分析软件,可以为四川地区钻井工程设计以及现场优选钻井液密度提供科学的依据。

| Abstract: | Aiming at a series of pipe-sticking caused by clay shale collapse in Sichoan gas field,a mechanical model is established from mechanics which is suitable for this area after verifying different kinds of predication methods for well bore stability and optimization.Through analyzing the relationship between well logging data and each elastic parameter for hole stability calculation,it is studied how to calculate the stable conditions with well logging data.The software for hole stability analysis can provide ... |
