| 摘 要： | 针对井间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。建立了以一口注入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 at the defaults of conventional interpretation method for inter-well tracer production curves, a new interpretation model for well-group tracer production curves was established. The objective function in the model is the minimization of match error for well-group tracer production curves, and the constraints include injection volume, area controlled by wells and others static and dynamic parameters. It is difficult to get partial derivative in least square fitting method, and the problem was avoided by using genetic algorithm to match the production curves. The automatic matching for tracer production curves was realized, and the solution speed and precision were improved. The application result shows reliability of the combination interpretation method. |
