|
Abstract:
基于MTA (Mud Cake to Agglomerated Cake，即泥饼仿地成凝饼)方法，分析了MTA的化学反应方程、固化反应过程、固化反应动力学模型、凝饼胶结形成过程和地质成岩模式，给出MTA解决水泥–地层界面问题的力学性能、微观结构和流体溶蚀等实验证据，对进一步改进MTA方法和解决水泥–地层界面封隔问题具有一定的指导意义。
Based on MTA (Mud Cake to Agglomerated Cake) method, the chemical reaction equation, solidification reaction process, solidification reaction kinetic model, cake cementation process and geological diagenesis model of MTA are analyzed, and experimental evidences such as mechanical properties, microstructure and fluid dissolution of MTA to solve the problem of cement-formation interface are given. It has certain guiding significance for further improving MTA method and solving the isolation problem of cement-formation interface.
