| The analysis between water injection and oil production is an important tool for planning the scheme in oilfield. It has been widely used to make the development plan in a single well or/and a block. On the base of the BP nerve network theory, this paper established the formation pressure model. The software was development to analyze water injection and oil production system, which turn the mechanism model into the function way. Therefore, we need not study the complex process through the water injection to the oil production well. The software can be used not only in analyzing the water injection and oil production, but also in the oil production and water injection respectively. It has been used in 17 wells(8 oil production wells and 9 water injection wells) in Changqing oilfield. The forecast shows a good agreement with the field data. The analysis between water injection and oil production is an important tool for planning the scheme in oilfield. This method is so good that the oil production and water injection works properly. It also can supply the scientific measures to adjust the oil production technology, which improve the development and administrations in oilfield. |
