This is just a preliminary contribution – we welcome everyone to participate more actively in discussions on this forum. The more people involved, the more lively it becomes. Haichuan becomes even better with you here.

The directional drilling across the Tongming Strait is the core project of the Sinopec integrated refined oil pipeline project (Zhanjiang to Beihai). It starts from Donghai Island in Zhanjiang City and ends in Huguang Town on the opposite shore. The project presents technical challenges such as complex engineering geology, high environmental protection requirements, and limited space for prefabrication. With a total drilling length of 4,071 meters, it sets a record for the longest directional drilling distance for an undersea refined oil pipeline in mainland China. The refined oil pipeline connected to Sinochem Refining and Chemicals has a total length of 248 kilometers. Once completed, it will facilitate the efficient operation of refined oil pipelines in China’s southwestern provinces, overcome the challenges posed by insufficient resources for pipeline transportation as well as the difficulty in transporting resources from coastal areas, and ensure a stable supply of refined oil to Guangdong and the southwestern regions. The successful directional drilling passage not only laid the foundation for the pipeline to be completed on schedule and put into operation, but also provided valuable experience for the construction of long-distance undersea crossings for oil product pipelines.
