WIPO Patent Application WO/2019/242296
Kind Code:
A1
Abstract:
A method for obtaining a relationship model between a water injection well and an oil production well, and a method for determining production rate and water injection amount, which may comprise: acquiring working parameters and production horizons of each water injection well and each oil production well in a first oil and gas field development block within a historical time period (S100); and by using the working parameters as training data and the same production horizon as a constraint condition, machine learning the working parameters of the water injection well and the oil production well in the same production horizon in the training data, so as to obtain a relationship model between the water injection wells and the oil production wells in the first oil and gas field development block (S200). Thus, a relationship model is established between the water injection wells and the oil production wells by means of machine learning working parameters within the historical time period. As the model embodies the relationship between the working parameters of each water injection well and the working parameters of each oil production well, the model may be directly used to determine the production rate of the oil production well or the water injection amount of the water injection well, which is simple and convenient.
