摘要:
以典型的单一溶腔盐岩地下储气库为例,采用ANSYS15.0建立了盐岩储气库计算模型,并通过ANSYS-FLAC3转换软 件将所建模型导入岩土通用计算软件FLAC3D中,最后通过FLAC3D模拟了七种不同埋藏深度情况下盐岩储气库溶腔的变形 情况。数值模拟结果为:随着埋藏深度的增加,盐岩储气库位移近似呈直线增加,盐岩储气库应力同样近似线性增加; 溶腔中上部及溶腔直径最大处位移及应力最大,溶腔变形最大。根据模拟结果,推荐类似本文所建的盐岩储气库埋藏深 度应控制在800~1 000 m为宜,才能保证其运行过程中最大位移不高于1.19 m,最大应力不高于80 MPa。尽管通过 FLAC3D模拟的盐岩地下储气库溶腔形状过于单一,与实际盐岩地下储气库具有一定距离,但是不乏代表性,同样能够为 盐岩储气库运营期间的安全稳定性提供有益的借鉴作用。
Abstract:
Taking the typical salt rock underground gas storage with single cavity as example, a calculation model of salt rock gas storage was established by using ANSYS15.0 software, and the model was imported into the general geotechnical calculation software FLAC3D through the conversion software ANSYS-FLAC3. The cavity deformation of salt rock gas storage under seven different buried depths were simulated through FLAC3D. The results showed that the displacement and stress of salt rock gas storage approximately presented a linear increase with the increase of buried depth. The maximum displacement and stress located at the upper part and the position with the largest diameter of cavity, and the deformation of cavity was the largest. According to the simulation results, the recommended buried depth of salt rock gas storage similar with the example in this paper should be controlled between 800-1 000 m, which can ensure the maximum displacement to be not more than 1.19 m and the maximum stress to be not more than 80MPa in the operation process. Although the cavity shape of salt rock underground gas storage simulated by FLAC3D was too simple, with a certain distance to the actual situation, but there is no lack of the representative, and it can also provide some meaningful references for the safe stability in the operation process of salt rock gas storage.
