Abstract
Due to factors such as objective conditions, time, and cost, it is impractical to carry out substantive indoor physical modeling experiments. Numerical simulation, whilst serving oilfield computation, is an economic technology with high speed and repeatability. Based on some typical physical modeling experiments, this paper establishes a numerical simulation model on laboratory units which complies with the experiments. This model aims at fitting displacement experimental dynamics and calibrating parameters in physical modeling experiments. Via this modeling and taking the experiment on profile controlling and flooding with weak gel as an example, computations over several schemes are accomplished, which visually reveal the mechanisms of fluid direction change, oil displacement, and injection profile improvement. The results demonstrate this approach a perfect combination of physical model experiment and numerical simulation, therefore can be widely used in a variety of displacement experiments for oilfield development, to achieve comprehensive studies while saving time and cost.
