Abstract: Through the study on water flooding effect of Q2 block reservoir with production dynamic and tracer data, combining the static modeling, it is realized that the directions on producers from injectors can be divided into 5 types: along main permeable reservoir direction (i.e. main variogram direction of porosity), along secondary permeable reservoir direction, along fracture direction, along main permeable reservoir direction that attached to the end of fractures, as well as open fault trend. The producers perform better from water injection if they are put in the main permeable reservoir direction with injectors. Injectors should be avoided being drilled near open faults. In the main reservoir, the injectorproducer pairs are better performed in the lower reservoirⅡ than that in the upper reservoir
