Prestack Description of Multilayer Reservoirs in Jian'ge Area, Sichuan Basin

Abstract

Abstract: New breakthrough has been made in Changxing Formation of Longgang 62 well and the third member of Xujiahe Formation of Jianmen 102 well recently, which indicates that reef reservoir of Changxing Formation and clastic reservoir of Xujiahe Formation have great exploration potential. Based on comparing and analyzing the dada in work area, PP-PS joint inversion, curvature attributes and instantaneous amplitude are used in the study. The platform-edge is described accurately; clastic rock fracture development and favorable hydrocarbon accumulation zones are forecasted. The study has brought about accurate data for further exploration, and a set of technical countermeasures are developed.

Key words: Sichuan Basin, PP-PS joint inversion, curvature attributes, instantaneous amplitude
