| 摘要: |
| 针对井苘示踪剂产出曲线解释方法存在的问题,提出了井组示踪剂产出曲线的解释方法。建立了以一口注人 井对应的多条产出曲线总体拟合最优为目标函数、以相应的注水量和井组面积等静、动态参数为约束条件的解释模 型。利用遗传算法实现了产出曲线的自动拟合，避免了最小二乘法中求偏导数困难的问题，提高了求解的速度和精 度。实例应用表明，提出的解释方法具有较强的可靠性。 |

| 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. |
