摘要
利用相空间重构方法对复杂油田产量序列进行了定量化的混沌特征分析, 通过计算其分维数和最大李雅普诺夫指数, 证实在油田这一复杂非线性系统中, 某些情况下确实存在混沌特征, 并给出混沌意义上的最大预报时间尺度。
Quantitative chaotic analysis is carried out on production series of complicated oilfield based on the theory of phase space reconstruction. Through calculation of its fractal dimension and the largest Lyapunov exponent, it has been proved that chaotic characteristics do exist in the complicated non-linear system of this kind of oilfield and furthermore the maximum predictable time length, which possesses chaotic significance, is also given in some cases.
