Abstract

The invention provides a method and device for determining a development mode for an oil reservoir based on the production prediction data of the oil reservoir. The method includes the following steps: according to feature parameters of the oil reservoir, acquiring the production prediction data of the oil reservoir under different pressure steps when using different development modes; according to the production prediction data of the oil reservoir under different pressure steps when using different development modes, acquiring the time steps of the oil reservoir when using different development modes; and according to the time steps of the oil reservoir when using different development modes and according to the production prediction data of the oil reservoir under different pressure steps when using different development modes, determining an optimal development mode for the oil reservoir. The method can be used for determining a development mode for the oil reservoir according to the production prediction data of the oil reservoir and thus is efficient.

Description

technical field [0001] The present invention relates to the field of reservoir evaluation in oil and gas field development, in particular to a method and device for determining a reservoir development mode based on reservoir production prediction data. Background technique [0002] In recent years, with the increasing difficulty of domestic large-scale reserves exploration, the poor quality of newly discovered resources, and the further deepening of the development of old oilfields, domestic undeveloped reserves tend to be inferior, showing "small scale, scattered distribution, large buried depth, The characteristics of poor physical properties and low abundance are manifested in the characteristics of "low yield and low efficiency" during the development process. Under the background of low oil price data, reservoir production prediction and processing of prediction data are the key issues of current research. [0003] Based on the reservoir production forecast data, deter...
