Model and technologies of subtle traps identification in irregular geologic body: An example of fan body traps
Online published: 2013-11-26
It is difficult to effectively forecast irregular geologic body by using common geophysical techniques because of its strong elusive features and great difficulties on identification. Seismic sedimentology and geophysical techniques provide favorable theory guidance and technical support for effectively forecasting subtle traps in irregular geologic body. Setting up correlative relationship among seismic attributes, sedimentary facies and subtle traps is the basis for effectively identifying subtle traps, and seismic facies analysis, wavelet frequency-division, facies controlling inversion are the key techniques. The prediction and exploration of fan body traps of lower Sha 3 member in Che 15 well field in Chezhen Sag show that the model of “integration of seismic and geologic, integration of theory and techniques” for subtle traps identifyication has greater application value.
