Study on a New Evaluation Method of the Use Condition of Water Flooding

Abstract:

The evaluation of use condition mostly depends on the test data, but lacking of data points or being limited by the accuracy of measurement at present. In order to solve this problem, this article studies on a new evaluation method of the use condition of water flooding, which based on the relationship between cumulative injection pore volume multiple and the water saturation. Firstly, using the data of water absorption, dynamic data, static data, and the development conditions to split injected water into small layers, and then distribute the liquid volume to the well based on the similar principle of water and electricity. Refer to standard of water level, determines the normalization and the limit of cumulative injection pore volume multiple. After the normalization of cumulative injection pore volume multiple as criteria of the evaluation of oil layers use condition. This method has been applied in A Block of Daqing Oilfield and the results are in good agreement with the results of interpret of well logging.
