Evaluation of Water Flooding Development Effect by Using Water Storage Rate and Water Flooding Index
Journal Title: Scholars Journal of Engineering and Technology - Year 2017, Vol 5, Issue 6
Abstract
Because the edge water is not active and natural energy field is not sufficient, it is quite difficult to develop the low permeability reservoir. The formation pressure can be supplied through water flooding which is the core development technology for low permeability reservoir. However, the evaluation of water flooding development effect plays a vital role to further improve the development effect and enhance the final recovery. In this article, the theoretical calculation formula of two indicators including water storage rate and water flooding index were listed out, their relationship to water cut were analyzed respectively, and the reason to cause the difference between theoretical value and actual value was pointed out. Finally, these two indicators were used to evaluate the water flooding effect with X oilfield. Keywords: Water storage rate; Water flooding index; Water cut; Development effect evaluation.
