仵杰,胡启,汪文秉.阵列感应测井测量信号聚焦的研究及应用.测井技术,1997,21(5):310~317研究了阵列感应测井中测量信号的聚焦问题。应用离散化技术、相关技术和软约束技术解决了用最优化方法设计最佳聚焦滤波器和高电导率信号的聚焦处理问题。研究了测量误差传播的控制和目的函数的选择,提出应根据分辨率随探测深度增加而下降的物理特性,合理选择不同探测深度的分辨率,即真分辨率聚焦,它具有最少的人为影响和最小的错误解释。为了解决实际测量受趋肤效应影响的问题,研究并实现了一种自适应非线性聚焦处理算法。用测井实例处理结果说明了真分辨率聚焦和自适应非线性聚焦处理算法的有效性。
Jie Jie, Hu Kai, Wang Wenbing. Research and Application of Array Inductive Logging Signal Focusing. Logging Technology, 1997,21 (5): 310 ~ 317 The focusing problem of measuring signals in array induction logging was studied. The discretization technique, the related technique and the soft constraint technique are used to solve the problem of focusing processing for designing the best focusing filter and the high-conductivity signal by the optimization method. The control of propagation of measurement error and the selection of objective function are studied. It is proposed that the resolution of different probing depths, ie the true resolution, should be selected reasonably according to the physical characteristics of the resolution decreasing with the increase of the detection depth. Minimal error explanation. In order to solve the problem that the actual measurement is affected by the skin effect, an adaptive non-linear focusing algorithm is studied and implemented. The results of logging example processing illustrate the effectiveness of true-resolution focusing and adaptive non-linear focusing algorithms.
