Feasibility Analysis of Water Injection Development Based on Geological Reservoir Characteristics
The characteristics of geological reservoirs are an important means to evaluate the feasibility of water injection development. The differences in reservoir characteristics in different regions make it difficult to scale up the promotion of water injection development parameters. A more effective way is to establish efficient water injection development methods and strategies suitable for the region. Therefore, based on the geological characteristics of the Wucangbao Chang 6 and Chang 9 oil reservoirs, the feasibility of water injection development in Wucangbao reservoir is analyzed from several aspects such as interstitial material content, reservoir hydrophilicity, and stress sensitivity. The water injection parameters of Wucangbao Chang 6 and Chang 9 single wells are calculated using methods such as apparent flow rate method, permeability and single well productivity regression method, and stratigraphic series curve regression method, respectively. The water injection parameters are obtained based on the single well production. The results show that the Wucangbao Chang 6 and Chang 9 reservoirs have good water injection feasibility and prospects in terms of sandstone cement, reservoir fluid properties, wettability, and water flooding efficiency; And the production of single well Chang 6 is 1.5-4.0 t/d, while the production of single well Chang 9 is 2.0-4.5 t/d; According to the injection production balance, the initial single well injection volume of the Wucangbao Chang 6 layer is 10 m3, and the initial single well injection volume of the Chang 9 layer is 20 m3, in order to maximize the recovery rate of the reservoir during the dry or low water cut period.
