Optimization of the well pattern of Es2x low-permeability reservoir of Dalujia Lin-56-4 fault block by numerical simulation

Es2x low-permeability reservoir of Dalujia Lin-56-4 fault block is a low-permeability fault block reservoir with large edge water, great dip and small oil areas, and its well pattern arrangement and the coordination of well pattern arrangement with edge water are the key to the effective development of the reservoir. Based on fine reservoir description data and various tested data, the well pattern arrangement of the reservoir is optimized by means of fine reservoir numerical simulation. The result of this paper can provide the guidance for the adjustment of the overall development plan of this kind of reservoirs.
