Storehouse Seepage Analysis during the Construction and Operation Period

Seepage analysis is important for the water-sealed underground oil reserves design.In this paper,feasibility study project is an example, carried out the calculation of the construction period and forecast of operation period, which are two aspects of the flow field characteristics of the analysis.In the flow field characteristics analysis of the construction and operation period, based on the establishment of the initial flow field model, FLAC3D stress and flow coupling module is used to carry out simulation caculation. According to the caculation results of the stable groundwater level and vertical hydraulic gradient, water-sealed effect is evaluated.We can see that the water-sealed storage design meets with the evaluation criteria,and this research work has a certain reference value for the similar projects.
