| Abstract: |
| Aimed.al the defaults cf conventional inteipnetation method for inter-well tracer production curves, a new interpretation model for well-group tracer production Cttrves was established. Hie objective function in the model is the minimization of match error for we!I-group tracer production curves，and the constraints include injection volume，area controlled by wells and others static and dynainic parameters It is difficult tr> get partial derivative in least square fitting method, and the problem was avoided by using genetic aJgorithm to match die prodtitiiion curves. The automatic matching for tracer production curves was realized，and the solution speed and precision were improved. Hie application result shows reliability of the combination interpretation method. |
