Abstract
The igneous-related oil and gas reservoirs have gradually become the major areas for oil exploration in Bohai oil field. But seismic data of igneous rocks are of poor quality, seriously affecting the understanding of igneous rock’s development pattern and structure implementation and reservoir prediction. To this end, this paper use forward modeling to demonstrate the effect of low frequency in volcano body imaging firstly; secondly, the paper puts forward the technical idea of using low frequency protection and enhancement technology to improve the imaging quality of the actual data of igneous rock zone, and we have focused on the three aspects of data processing, as mathematical morphology noise suppression technology based on low frequency protection, deconvolution technique using larger prediction gap, and low frequency enhancement based on generalized S transform; finally, the comparison of the results shows that the technology sequence can effectively improve the imaging quality of the volcano body, and it has some promotional value.
