Abstract

Taking “Beads” as exploration objects,Tazhong gas field achieved some effects.With the development of exploitation,we found that “Beads” are not the main features of gas reservoirs,and “Beads” are fewer and fewer.We need to recognize the distribution regularities of gas reservoirs to seek the effective prediction methods.This paper shows that,Tazhong area has been uplifting after the sedimentation of Yingshan Formation,which is influenced by the interaction of differential corrosion and segmentation of strike-slip faults,resulting in the strong heterogeneity of reservoir distribution and the complexity of gas-water distribution.Despite the Yingshan reservoir has complicated distribution and strong anisotropy,through the logging data analysis we found the most sensitive pre-elastic parameters of Yingshan gas reservoirs-Poisson's ratio.AVO modeling shows Yingshan gas reservoirs have three types of AVO abnormal.That means the “Near-Far AVO characterization” and the “Major amplitude & Major frequencies” can predicate the gas reservoir and increase the drilling rate.It is significant in the carbonate exploitation.

Key words： Carbonate; Reservoirs of Yingshan Formation; Differential corrosion; Near-far offset traces characteristization; Gas and water identification
