摘　　要：我国常用的储气库建造方法为单井油垫法,在建库过程中,只注重于腔体形状的控制而不考虑盐矿资源的利用。为此本文采用Salt Cavern Builder V1.0软件对建腔过程进行仿真,对不同提管方式、不同流量以及不同夹层赋存状态的水溶采盐及造腔规律进行研究,研究结果表明,在三种提管方式中,提中间管不仅在产盐上是最优的,且在造腔效率以及腔体形状控制上也是最优的;注水流量对浓度的影响主要在造腔前期,流量对腔体形状的影响主要体现在高径比上,30m^3/h^120m^3/h流量下的腔体高径比分别为2.5、1.74、1.45、1.36。夹层数目增多时,盐腔边界出现不规则,且夹层数目越多,这种边界不规则性更加明显。The single-well solution mining technology was widely used in gas storage cavern construction in China,the cavern profile but not salt resources were emphasized.The solution mining process was simulated by Salt Cavern Builder V1.0 software,the law of solution mining and cavern construction influenced by casing arrangement,injection flow,and interlayers occurrence were researched.The results show that,raising intermedium pipe was the best casing arrangement manner in the aspects of salt production,construction rate,and cavern shape.The earlier period of cavern construction was influenced by injection flow,the height-diameter ratio was 2.5,1.74,1.45,1.36 respectively at flow of 30m3/h^120m3/h.The boundary of cavern was more irregular with more interlayers.
