Automatic separate layer model based on the phase-space reconstruction and improved optimum division method

This paper introduces the automatic separate layer model based on phase-space reconstruction and optimum division method. In order to reduce noise for the model, the nonlinear noise reduction method is proposed in dealing of log data,then reliability of automatic separate layer is promoted. The new statistic is introduced to ascertain the depth of the layer. In the last, its practicability and reliability are demonstrated by the practical log data in western Sichan Province.
