Abstract:
To solve the problem of great deviations about the forecasted permeablity calculated by the normal model of permeability prediction, which cannot be satisfied with the requirements of reservoir numerical simulation in medium- and later-period of oilfield exploration,after analyzing the influential elements systematically about the reservoir permeability, which comprise reservoir lithology, porosity, shale volume etc, this paper advances that: at first, should identify the reservoirs lothology by adopting the well logging curves and the cross plot technology; then, establish different models of permeability prediction according to different reservoir types.This method considers the influences of reservoir lithology, porosity and shale volume on permeability synthetically. The applications to Peru B Oilfield gets fine gelological effects, and shows that the precisions of permeability prediction had been improved greatly, which gives fine foundations for stipulating for adjustable plans of oilfield exploration in later period.
