Mixed transportation optimization model for oilfield water injection synergizing pipeline network and trucks
Geoenergy Science and Engineering(2024)
摘要
The water injection network is a common method in oil extraction processes, generally characterized by high energy consumption. Therefore, the adoption of scientifically sound and rational optimization schemes is crucial. However, due to the limited injection capacity of water injection station (WIS), when their supply is less than the demand of the injection wells, trucks are used for supplementary water injection. This paper introduces an oilfield water injection method under water injection pipeline and trucks coordination transport. An optimization model for oilfield water injection in this mixed transportation mode is established to address the supply-demand imbalance in the water injection network. The study uses a specific oilfield water injection system as a case study to validate the applicability of the mixed transportation water injection model (MTWI-Model) compared to the conventional water injection model (CWI-Model). The findings indicate that when only CWI-Model is used, the water volume from the injection station cannot meet the demands of the injection wells, leading to the cessation of some wells and potential overload of pumps in the station, thus affecting the normal operation of the water injection station and ultimately the oil recovery rate. Furthermore, the paper compares the optimization results of the mixed transportation model under two scenarios: fixed and non-fixed water intake points (namely MTWI-FP-Model and MTWI-NFP-Model). The results show that the mixed transportation mode with non-fixed water intake points is more economical, saving a daily cost of 632.28 Yuan/d compared to the fixed point scenario.
