| Abstract: | Abstract As a new developing method, fishbone well injection has been used in buried hill reservoirs. Based on numerical simulation, optimization research on the new reservoir developing method, which means fishbone wells injecting water at the bottom and horizontal wells producing oil at the top, is present. Compared with horizontal well injection, the results show that the fishbone well can increase the control area, form planar flooding, and hold the injection water upward slowly and evenly. The reasonable fishbone well parameters, such as branching angle, branch number, and branch length, are obtained. The fishbone well injection provides a new technical method for developing buried hill reservoirs efficiently. |
