Original abstract

Water injection demand for oilfields varies greatly in different development periods. The topology and size of the water injection pipeline network should match the changing demand. Long-term benefits should be considered to avoid the frequent expansion of the network. This paper considers the water demand in multiple periods and develops an MINLP model to optimise the layout and size of the water injection pipeline network for existing pipeline networks. The model aims to minimise construction cost and operating cost. Both pipeline transport and truck transport are considered with pressure constraints, pipeline pressure drop constraints, flow constraints, and supply-demand balance constraints. A piecewise linearisation method is proposed to avoid nonlinear terms in pressure drop and cost constraints. A case from an oilfield in Northwest China is taken as an example to verify the model. The water injection planning of an existing water pipeline network in the future three periods is determined. The results show that 14.6% of the total cost can be saved in the final phase compared to the first phase, which mainly benefited from the reduction of truck transported water volume.
