玻利维亚至巴西输气管道系统的施工已近尾声,目前这一地区的管道施工重点正转向大口径越境天然气管道的建设。 玻利维亚至巴西的2 900km的输气管道于1997年底投入施工,此前已进行了25年的研究论证,目前主干线已进入紧张施工阶段。与此相似的是另一条837km、直径508mm的自阿根廷至智利的输气管道。当前与今后的越境输气管道项目还包括自阿根廷的布宜诺斯艾利斯至乌拉圭的蒙迪维地奥、秘鲁至巴西、玻利维亚至巴西的管道。另外,阿根廷至智利康塞普森的 The construction of gas pipeline system from Bolivia to Brazil is almost completed. At present, the focus of pipeline construction in this area is turning to the construction of large-diameter cross-border natural gas pipeline. The 2,900-km gas pipeline from Bolivia to Brazil was put into operation by the end of 1997 and 25 years of research and feasibility studies have been carried out. At present, the main trunk line has entered a period of intense construction. Similar to this is another 837km, 508mm diameter gas pipeline from Argentina to Chile. Current and future transboundary gas pipeline projects also include pipelines from Buenos Aires, Argentina, to Montevideo, Uruguay, from Peru to Brazil and from Bolivia to Brazil. In addition, from Argentina to Concepción, Chile
