Abstract

To study the significance of different factors on adjacent underground laminated salt rock storage, 15 groups of simulation tests are designed by using the response surface methodology (RSM), the quadratic response surface model with the midpoint displacement and medial waist stress of the interlayer as the response values is constructed. By analyzing the main effect and interaction of the regression model, the influence of the interaction between pillar width, interlayer thickness, and the location of a single interlayer on the midpoint displacement of the interlayer and the internal waist stress of the adjacent ellipsoidal cavity is studied. The results show that the interlayer thickness is the main effect factor of the midpoint displacement of the interlayer. And the pillar width is the main effect factor of the medial waist stress. When the adjacent storage is designed with as 2.5D pillar width, 2 m interlayer thickness, and the midpoint of the interlayer is located at 0.3H above the cavity, the displacement and stress of the test model are relatively small. The above conclusions can provide a certain reference value for the mechanical analysis of adjacent underground layered salt rock gas storage.

基于RSM的相邻地下层状盐岩储气库多因素优化研究

为研究不同因素对相邻地下层状盐岩储层的影响，采用响应面法设计了15组模拟试验，构建了以夹层中点位移和中层腰应力为响应值的二次响应面模型。通过分析回归模型的主要作用和交互作用，研究了矿柱宽度、层间厚度和单个层间位置的交互作用对层间中点位移和相邻椭球腔内腰应力的影响。结果表明:层间厚度是影响层间中点位移的主要因素;矿柱宽度是影响中腰应力的主要因素。当相邻储层柱宽为2.5D，层间厚度为2m，层间中点位于空腔上方0.3H处时，试验模型的位移和应力较小。以上结论可为相邻地下层状盐岩储气库的力学分析提供一定的参考价值。

期刊介绍： Scientific Mining Journal, which is published i n open access electronic environment and i n printed, is a periodical scientific journal of Union of Chambers of Turkish Engineers and Architects Chamber of Mining Engineers. The name of the journal was "Mining" until June 2016 and it has been changed to "Scientific Mining Journal" since September 2016 because it can be confused with popular journals with similar names and the ISSN number has been updated from 0024-9416 to 2564-7024. Scientific Mining Journal, published four times a year (March-June-September-December), aims to disseminate original scientific studies which are conducted according to the scientific norms and publication ethics at national and international scale, to scientists, mining engineers, the public; and thus to share scientific knowledge with society. The journal is in both Turkish and English. The journal covers theoretical, experimental, and applied research articles, which reflects the findings and results of an original research i n the field of mining engineering; review articles, which assess, evaluates, and interprets the findings of a comprehensive review of sufficient number of scientific articles and summarize them at present information and technology level; technical notes, which may be defined as a short article that describes a novel methodology o r technique; a case studies, which are based on the theoretical o r real professional practice and involves systematic data collection and analysis.
