Abstract: Qingcheng shale oil reservoirs have strong lateral and vertical heterogeneity, low brittleness index, and low reservoir pressure coefficient, necessitating large-scale volume fracturing. However, the complex topography of the Loess Plateau, characterized by arid conditions and water scarcity, poses a challenge of insufficient water supply for large-scale volume fracturing. In response to these issues, a numerical simulation method was used to optimize the fracturing energy enhancement mode. The internal wells were divided into energy enhancement wells and non-energy enhancement wells to improve liquid utilization and achieve the goal of both energy enhancement and water reduction. Through differentiated fracturing process parameters for energy enhancement and non-energy enhancement wells, and optimization of fracturing sequences, a structured oil displacement fracturing technology was innovatively formed. This technology not only increased the formation energy within the well group and maximized the degree of fracture control but also improved the issue of insufficient water supply for fracturing. The technology has shown good results in the Qingcheng shale oil field. Compared with conventional volume fracturing, it saves an average of 5000 cubic meters of fracturing fluid and 1200 cubic meters of proppant per well, with an initial production increase of 1.1 t/d. The structured oil displacement fracturing technology can reduce costs and increase efficiency, and it has good value for field promotion and application.
