摘要
为了确定油田注水管网中注水方案,采用一种正演反演迭代的算法。该算法的主要思想是:对于油田注水管网首先进行反演计算,计算泵站的需求流量,然后进行正演计算,判断所有注水井是否满足配注要求,如果所有注水井满足配注要求则停止计算,否则减少不满足的注水井一定步长的需求配注流量,进入下一次迭代运算。该算法不需要列写注水管网系统方程组,实现简单,使用迭代方法,适合计算机编程。实验结果表明,该算法具有快速性和准确性。
For determining the injection program of oilfield water injection pipe network,a forward and iterative inversion iterative algorithm is adopted in this paper. The main idea of this algorithm is：calculate the demand flow of pump station according to inversion calculation of oilfield water injection pipe network,and then judge whether all the water injection wells have met the water injection requirements according to the forward calculation. If all the wells meet the water injection requirements,the calculation is stopped. If not,the algorithm reduces the demand flow of the wells which do not meet the requirements,and then enter into the next iterative operation. The algorithm does not need to write equations of the water injection pipe network system. The algorithm is simple and the iterative method is suitable for computer programming. The experimental results show that the al-gorithm is fast and accurate.
