| description | W27 oilfield is a multi-layer heterogeneous low permeability reservoir, which has entered the middle and late stage of development. The main reservoir is flooded seriously, and the remaining oil distribution is complex. If conventional fracturing technology is adopted, the risk of longitudinal fracture communication with water layer or water-flooded layer is high, which is easy to cause high water cut after fracturing and affect the fracturing effect. According to the characteristics of fractured well reservoir, the hydraulic injection fracturing technology is optimized to optimize the position of injection point and fracturing process parameters, avoid pressing water layer, and achieve accurate reconstruction of potential reservoir. The technology was applied to 4 Wells on site, and the average daily oil gain per well was 6 tons and the average accumulated oil gain per well was 2,500 tons. Hydraulic injection precision fracturing technology has an obvious effect on water control and oil increase in W27 oilfield, which has an important guiding significance for similar reservoirs to improve the fracturing effect. |
