随着我国石油工业突飞猛进,老油田不断发展扩大,新油区不断发现和建设,油田地面建设对多种管道的需要量也日益增加。这样每年国家在油田地面建设管道方面就要消耗大量的钢材。因此,用水泥管代替钢管,可以节省钢材,加速我国石油工业的发展。自一九七二年开始,在胜坨油田和孤岛油田就铺设和试用了,国家建委建材研究院、辽宁水泥研究设计所、江西水泥制品研究所、上海橡胶制品研究所、南京水泥制管 With the rapid development of China’s oil industry, the continuous development and expansion of old oilfields, the constant discovery and construction of new oil fields, and the increasing demand for various pipelines for oilfield surface construction. In this way, every year, the state consumes a large amount of steel in the construction of pipelines on the oil field. Therefore, the use of cement pipe instead of steel, steel can be saved and accelerate the development of China’s oil industry. Since 1972, the Shengtuo Oilfield and Gudao Oilfield have been laid and tested.
