复杂对流井连通老腔改建储气库技术
|
摘要
盐化公司拥有丰富的对流井老腔资源,如果能够有效利用此类腔体,不但可以缩短储气库建库时间,而且可以大幅降低工程投资。介绍了盐化溶盐采卤生产模式,基于数值模拟与声呐检测数据,探讨对流井采卤老腔改造过程中存在的形状检测、注气排卤模式等难点,论证了对流井老腔改造的可行性,提出对流井改建储气库的方法。盐化公司对流井老腔改造技术拓宽了盐穴储气库建设的新思路,尤其是针对中国普遍夹层多、纯度低的盐层改建储气库具有重要意义。
Salt & Chemical Company has abundant resources of convection connected salt caverns. And if this type of salt cavern is utilized effectively, not only the reconstruction time of gas storage is shortened, but also the engineering investment can be reduced significantly. In this paper, the salt brine production model of Salt & Chemical Company was firstly reviewed. Then, based on numerical simulation and sonar detection data, the difficulties in the reconstruction process of existing convection connected salt caverns were investigated, such as shape detection and de-brining mode. Finally, the reconstruction feasibility of existing convection connected salt caverns into underground gas storage was discussed, and the reconstruction method was put forward. In conclusion, Salt & Chemical Company's technologies for the reconstruction of existing convection connected salt caverns into underground gas storage broaden the construction ideas of salt-cavern gas storage, and especially are of great significance to the construction of underground gas storage in salt layers with multiple interlayers and low purity in China.
