The geological model is established with Software Petrel. Then by Eclipse, numerical simulation is done. The development index of block well pattern and remaining oil change condition of well pattern are forecasted. At the same time, comparisons are done between theoretical relationship curve and actual data curve of recovery extent and water cut for the whole block and sublayers. Adaptability is analyzed for block well pattern. Results show that when the water cut of the whole block arrives above 50%, there is lifting liquid capability, to a maximum of 1.5 times. Numerical simulation predicts that, when the comprehensive water cut arrives at 98%, there are still a lot of remaining oil pool areas; for poor well pattern adaptability, it is necessary to adjust block network infilling and water injection pattern. The results provide basis for the well pattern optimization adjustment and also provide theoretical direction for the actual production of other blocks.
