Based on the earlier-stage research integration and by referring to the micro-service thinking, the practice is conducted in the earlier-stage research projects of Bohai Oilfield. Assisted by the multi-level technical team training and information sharing integration, the application of integrated micro-service mode of earlier-stage research is realized in marginal Oilfield L, and the earlier-stage research scheme is of development benefits. The practice proves that the mode can greatly accelerate the oilfield production time, and can be widely used in the earlier-stage research in the future, which is of great significance in ensuring the production targets and energy reserves of Bohai Oilfield.
