Abstract
With the accelerated construction and aging of underground oil and gas pipelines, trenchless technology (TT) has developed rapidly in recent years. This paper briefly introduces the trenchless installation, repair (rehabilitation), replacement, and cleaning technologies that can be used for oil and gas pipelines. Advantages, limitations, technical features, and application scopes are summarized to provide a basis for construction method selection. In addition, this paper collects twenty standards related to trenchless construction technology for oil and gas pipes, so as to quickly identify the standards to be referenced before construction. Finally, this paper analyzes the market for TT and presents key technical gaps.
