Prediction method for marl fractured reservoir———An example from Shulu Sag
Online published: 2007-09-15
Due to the anisotropy and heterogeneity of the marl fractured reservoir,it is difficult to predict the fracture accurately with conventional methods.Based on the theories of tectonic stress field,seismic wave frequency attenuation and fracture detection,the pseudo2acoustic inversion,digital simulation analysis of tectonic stress field, forward modeling of rock physical model and anisotropy and attenuation attributes analysis combining with the available data of geology, drilling, well logging and the prestack and poststack seismic data are applied to analyze the marl fractured reservoir in Shulu Sag. The relations among the marl fracture development and stratigraphic lithologies,stress distribution and tectonic development are made clear, and the distribution range of the favorable reservoir was finally predicted. The application result of the real data proves the effectiveness and reliability of this method in the reservoir prediction.
