摘要

摘要: 为有效反映盐岩油气储库介质的蠕变变形特征与变化规律，以金坛盐岩储气库为背景工程，根据地质力学模型试验相似原理和原岩物理力学参数，通过大量的材料配比和相应材料试件的力学参数试验，研制出了基本满足相似条件且具有显著流变特性的盐岩相似材料。该相似材料采用精铁粉、石英砂和重晶石粉为骨料，以松香酒精溶液为胶结剂按照规定的配比拌合压实而成。材料力学试验表明：研制的盐岩相似材料具有明显的弹性变形、延塑性变形、应变硬化、应变软化和剪涨破坏特征。材料在低应力时以减速蠕变和等速蠕变为主，高应力时以减速蠕变、等速蠕变和加速蠕变为主，盐岩相似材料与盐岩原岩的蠕变特性基本一致。将该材料应用到金坛盐岩地下储气库注采气三维地质力学模型试验中，有效获得注采交变气压变化过程中洞周径向位移和径向应变的变化规律，较好反映了盐岩储库介质的流变力学特性。

Abstract: In order to reflect the creep deformation and change law of the salt-rock gas storage effectively, a kind of salt rock-similar material is obtained based on Jintan Salt Rock Gas Storage after a great number of tests on material ratio and mechanical parameters according to the similarity principle of geomechanical model tests and mechanical parameters of the original rock. The rock salt similar-material which satisfies the similarity principle basically and has significant rheological property is evenly pressed by means of iron ore powder, blanc fix, quartz sand, gypsum powder, rosin and alcohol where iron ore powder, blanc fix and quartz sand are main materials and the solution of rosin alcohol is cementing agent. The mechanical tests show that the similar material has obvious characteristics of elastic deformation, ductility and plastic deformation, strain hardening, strain softening and dilative shear failure. Moreover, the salt rock-similar material shows transient creep and steady-state creep under the effect of low press, and shows transient creep, steady-state creep stage and tertiary creep under the effect of high press. The rheological property of the salt rock-similar and salt rock is basically consistent. The similar material is applied in the 3-D model tests on salt rock gas storage under alternating gas pressure. The rule of radial displacement and radial strain is obtained effectively and the rheological behavior of the salt rock gas storage is simulated well.
