Abstract:

When the conventional optimization algorithms are applied to optimized development of large scale reservoirs, the problems such as slow convergence speed, low optimization efficiency and difficult integration with field applications occur. To solve these problems, a well production performance control model was established. A global optimal solution of the model was found by using the simulated annealing genetic (SAG) algorithm and Latin hypercube sampling (LHS) algorithm. Furthermore, the convergence speed of the local solution of the model was accelerated by using the synchronous perturbation stochastic approximation (SPSA) algorithm, and a well production performance control software was developed and applied to the H block in Daqing oilfield. Compared with conventional well production systems, the best scheme of the optimized well production performance control model increases the cumulative oil production of H block by 5.68×104 m3 within 5 years, which ensures the well production performance control and optimization, and provides a new method for efficient development of large-scale oilfields.
