Abstract: China’s oil service enterprises need to prioritize petroleum engineering standardization and give it a fundamental and leading role to promote their technological innovation, lead their optimization and upgrading, improve their core competitiveness, and achieve high-quality development. In order to promote the process of petroleum engineering standardization in China, the development trend and challenges of petroleum engineering standardization were discussed, by starting from the analysis of the development status of petroleum engineering standards. The standard implementation achievements of Sinopec Oilfield Service Corporation were taken as an example to introduce the practices of petroleum engineering standardization from six aspects, including management structure, standard system, informatization construction, transformation of scientific and technological achievements, and standardized sites, while emphasizing the important supporting role of standardization in promoting the transformation and development of enterprises and improving the quality and efficiency of main business. On this basis, several suggestions and countermeasures were given for oil service enterprises in China to continuously promote standardization development, so as to realize the sustainable and rapid development of China’s petroleum engineering standardization.
