As the core research and development institution for oil field technology, the strategic positioning and implementation of the engineering technology research institute have a profound impact on the future development direction and competitiveness of the oil field industry. First of all, after consulting a significant amount of data through text analysis, this paper employs the PEST model to systematically analyse macro external factors. Secondly, utilizing the SWOT analysis matrix, it identifies the internal factors that influence the formulation of the enterprise’s development strategy and carries out qualitative text analysis. Finally, the paper measures the weight of relevant influencing factors by AHP, and then makes a choice for the development strategy of the Institute of Engineering Technology. After analysis and research, it is suggested that the best plan for the development of oilfield Engineering technology Research Institute is SO strategic combination, that is, to build a science and development system of “three markets and two major projects”, seize new opportunities such as green energy and digital intelligence, give full play to the core research capabilities of engineering research Institute, cultivate and develop new quality productivity, and strive to be the first in the engineering chain; Adhere to the four-in-one (original technology, senior talent, open platform, lean management) medium—and long-term strategic layout to achieve multi—dimensiona l development.
