To tackle the technical challenges, Qinghai Oilfield has launched targeted attacks on pain points. In the field of microgrids, except for the Xiandong 8 well project, the "Wind Solar Storage AC Microgrid" at the Yue9-381 well site has achieved long-term stable benefits, and the "Light Storage Direct Flexible Microgrid" at the Yuebei 1 well has introduced all vanadium flow battery technology, completely activating the autonomy of off grid well energy consumption; After the implementation of energy efficiency improvement technology in Wunan Photovoltaic Power Station and Thermal Mirror Field, the efficiency of 2 photovoltaic power stations and 3 thermal mirror fields has significantly improved. In the field of new energy storage, based on the advantages of oilfield well resources, three wells have been tested for "same injection and same production" compressed air energy storage. Through exploration, five core understandings have been preliminarily formed, vigorously seeking new paths for new energy storage technologies.
The effectiveness of technological breakthroughs is reflected in the transformation of achievements and the release of value. The technical breakthrough project of "scenery integrated intelligent foam and drainage operation device" has achieved remarkable results. The project has innovatively constructed a new mode of "clean energy drive+intelligent decision-making and control+unmanned operation", and has promoted and applied 153 sets in total. The annual cost of a single well has saved more than 60000 yuan. Its mature experience has important promotion value for the green and low-carbon transformation of foam drainage and gas production oilfield, and has successfully built the first zero carbon intelligent foam and drainage demonstration area in China; The wind and solar resource monitoring network constructed with 51 wind measurement towers has provided millions of accurate data sets for major projects such as the 2 million kilowatt wind power project in Haixi, saving up to 30% of the initial evaluation costs.
