摘要

Seismic attributes for the interpreting explorationist are numerous. Some are useful, some duplicative, and some less useful. However, with respect to optimizing a systematic basin analysis approach which relies upon heavily upon integrating seismic facies, there are eight particularly useful attributes which have dear geophysical meaning, strong underlying geological rock-fluid implications, and which for clastic depositional environments greatly assist in determining seismic facies, associated paleoenvironments, and lessening the number of interpretive possibilities. They are: Amplitude Envelope, Chaos, Cosine of Phase, Dip Deviation, Instantaneous Frequency, Q, Relative Acoustic Impedance, and Variance. A systematic application of these first order attributes for the East China Sea in particular, and for other clastic environments in general, allows a first pass assessment of a basin's exploration potential through seismic reconnaissance, an interpretive reconnaissance whose accuracy is limited only by the seismic fidelity of the lines and logic of the assumed geology employed.
