Since the “Eighth Five-Year Plan”, the practice of extracting fluid from low-water-cut wells and controlling fluid from high-water-cut wells has controlled the increase in water cut and the growth rate of fluid production, and achieved the goal of stabilizing oil and water. At present, the water cut of each well pattern is basically close, and the potential for structural adjustment is small. The effect of continuing to adhere to the previous adjustment of injection-production structure is not obvious. It is necessary to revise the injection-production structure adjustment policy to achieve balanced production of various oil layers and control production decline.
