Application of of Principal Component Prediction in Qingxi Oilfield

Abstract

Abstract: Principal component analysis and prediction is a technique of detailed well log constraint inversion. Based on well log data and seismic data, it can be applied to provide the wave impedance as similar as well log resolution in accuracy, including lithology and reser-voir rock parameters. Good results are obtained from its application to Qingxi oilfield in sedimentary facies classification， well location demonstration and integrated geological studies. Commercial oil flow has been found in four of six wells drilled in 2002, which contributes to Qingxi oilfield in its productivity construction.

Key words: Qingxi oilfeld, seismic interpretation, lithology, inversion, petrophysical parameter
