Abstract: The nodes of wireless sensor networks for oil and gas pipelines are linearly distributed according to the pipeline direction. It is unable to replace the batteries of the energy exhausted nodes in a large scale in time.Effective energy management has been a key factor restricting the performance of the oil and gas Internet of things. Network end-to-end delay determines the response time of network to pipeline accidents, so it is also a key parameter. The routing algorithm proposed in the paper uses energy acquisition technology to extend the service life of the network. The end-to-end delay of the network can be effectively reduced by selecting the node which is far away from the sender as the forwarding node. Simulation results show that the algorithm can effectively consider network lifetime and network delay, and improve network performance compared to other opportunistic routing protocols and protocols using energy harvesting technology.

Key words: the pipeline internet of things, wireless energy acquisition, opportunistic routing algorithm
