國光油窖實際設計施工及經濟效益
An introduction to actual design, construction and economic benefits in Kuo-Kuang L. P. G. underground storage
摘要
中國石油公司為配合本省北部自產液化石油氣之儲存，致力於探討發展地下岩層儲油窖，經地質調查，鑽採岩心，分析試驗，作可行性研究。擇定本省北部之錦水頁岩層內之『純頁岩段』具有良好之建造條件，並具穩定之地下水位，經在施工機具及工程技術詳加分析研究後，由臺灣油礦探勘總處施工。建造本省首座地下岩層儲油窖，容量50,000m^3儲存液化石油氣，並於民國六十七年十月開工，於民國七十一年六月建造完成；經試壓及吹驅後參加營運。本文就施工設計規範，施工方式及吹驅試壓經過，作一概要説明，並對施工有關問題提出檢討，作為將來再度施工之參考。儲油設施，建造於地下岩層，其優點甚多，如單位儲存容量之建造成本較低，維護及操作費用亦較節省，更可有效利用土地，維護儲存品之安全及維護景觀等效益。實值推廣。

For the storage of L. P. G. produced from the northern part of Taiwan, C. P. C. had made an effort to study and develop the construction of the underground storage cavern. C. P. C. selected the most favourable ＂pure shale member＂ belonging to the basal part of the upper Chinshui Shale located in Miaoli. This pure shale is the best environment for excavating an underground rock cavern to store L. P. G. The great construction of this first underground storage engineering work in Taiwan was succesefully achieved by the TPED, C. P. C. itself. The storage volume is 50,000m^3 for commercial L. P. G. In Oct. 1978, the construction was started and completed in June. 1982, then the cavern pressure test and purging was continued before formal use. This paper is intended to introduce the design and the method of the construction including pressure test and purging. We wish this paper is helpful for underground cavern construction in the future. The underground cavern has a lot of advantages, such as big capacity, low initial cost, low maintenance cost, good storage safety, and land saving as compared with the conventional L. P. G. spherical tank standing on the ground.
