Abstract:

In the early stage of shale oil development, the investment is large and the recovery factor is low, bringing great risk of economic loss. Therefore, it is necessary to combine different development methods to study its economic decision. To this end, based on the idea of the integration of numerical simulation method and reservoir development and management, firstly, the economic decision-making system and oil price index prediction are established, and then a series of new methods for the selection of development mode at different stages and different oil prices are improved through the combination and optimization of various numerical simulation schemes. Taking the shale oil of Kong-2 Member in Cangdong Sag of Dagang Oilfield as an example, different overall development program indexes are predicted. Finally, based on the idea of reservoir development and management integration, the suitable development programs for different international oil prices are selected. By comparing the changes of the cumulative net present value of the single production plan and the combined production plan, it is found that the single production method with higher recovery factor is not necessarily the economic optimal plan. Finally, the most economical development plan with different oil price ranges is obtained, and a set of optimal method for the economic and efficient development plan of shale reservoir is formed.

Key words: shale oil, numerical simulation, development and management, international oil price, economic decision
