In the past 10 years, oil and gas pipeline engineering relevant technology in China obtained rapid development. In this paper, new progress in relevant technology research of oil and gas pipeline engineering in China was systematically categorized. In pipeline transportation of waxy crude oils, technologies and applications, including batch transportation of cool and hot oil, long distance pipelining transportation of crude in batch with pour-point-depressant beneficiation and long distance pipelining intermittent transportation of waxy crudes, were introduced. In pipeline transportation of natural gas, new process and application of pipeline transportation of natural gas and LNG were discussed. In the aspect of pipeline transportation of products oil, controlling contaminated volume of products oil and batch planning of batch transportation were summarized. Finally, future development trend of oil and gas pipeline engineering technology in China was prospected.
