摘要

岩土介质多场耦合问题需考虑诸多因素，温度、渗流及应力之间的耦合关系复杂，试验条件不易控制，且难以实现，因此，辅以数值模拟手段具有重要的意义。基于混合物理论，推导出岩土介质温度、渗流和应力耦合的数学模型及其控制方程，提出该数学模型的求解方法，以MATLAB语言为平台，将Abaqus程序作为一个模块嵌入迭代算法程序中，编制了多场耦合分析程序，并给出了2个典型算例验证该方法的有效性和实用性。然后，将建立的多场耦合模型和计算程序应用于石油钻井施工过程的模拟，重点分析井壁围岩内温度场、渗流场和应力场的变化规律，以及钻井液温度的变化对井壁稳定性的影响。研究成果对我国地下石油、核废料储存等工程设计和施工具有一定的指导意义。

Abstract

Many factors

experimental conditions and complex coupled relations need to be considered in the multifield coupling of geomaterial. Therefore

it is much important to study the thermo-hydro-mechanical(THM) coupling problems using numerical simulation method. According to the continuum theory of mixture

a coupled model and the governing equations of the coupled problem of temperature

seepage

and stress field for geotechnical media are deduced. Strategy and methods to solve this mathematical model also are discussed. Based on the software MATLAB

the program of THM analysis is coded

in which Abaqus is embedded as a module in the iterative algorithm. Through two typical examples

the proposed THM program is verified; and the results show that this method is a very good analytical method and its efficiency is very good. And then the code of THM coupling model is applied to simulate the construction process of petroleum drilling and analysis of wellbore stability. The evolution law of temperature

pore pressure and stress field in surrounding rock are obtained. And the variations of drilling fluid temperature have significant influences on wellbore stability. The study has significant effects on the design and construction for underground oil and nuclear waste disposal.
