摘要：In the process of waterflood development in the mid-high permeability sandstone oilfield, one of the important indexes to evaluate the injection effect of water injection wells is the water injectivity capacity, which is can be expressed by water injectivity index. Based on the filtration theory and the principle of reservoir engineering, taking A Oilfield as an example which is five-spot pattern, this paper establishes theoretical calculation formula of dimensionless water injectivity index, and determines the transformation rule of actual water injectivity index and theoretical water injectivity index in different water content stages of mid-high permeability sandstone oilfield, this method has certain applicability because the theoretical calculation results and the water injectivity index results which is calculated from actual data is consistent, and it can provide theoretical basis for reasonable allocation and development adjustment of oilfield.
