Abstract
In this study, SAA (Simulated annealing algorithm) is used to optimize the well layout direction of tertiary infilling wells by water flooding. The specific research includes: (1) constructing a mathematical model for optimizing the well layout direction of tertiary infilling wells by water flooding; Design the search strategy of SAA; Simulation experiments are carried out to verify the effectiveness of the algorithm; Analyze the experimental results and put forward optimization suggestions. The simulation results show that the oil recovery after optimization is about 10% higher than that before optimization. This result directly proves the effectiveness of SAA in the optimization of well layout direction of tertiary infill wells by water flooding. At the same time, the convergence of the algorithm is good in the optimization process, which shows that the SAA is efficient in solving this problem. And the algorithm in this paper has good stability and consistency in many experiments. This result verifies the effectiveness and adaptability of the algorithm in this paper, and provides strong support for the practical application in oilfield development. Through this study, it is expected to provide new ideas and methods for optimizing the well layout direction of tertiary infilling wells by water flooding, and promote the innovation and development of oilfield development technology.
