Abstract
The conventional patterns of attribute extraction and calculation have many limitations for complex low level faults. Therefore, we propose a seismic attribute extraction pattern with the directional rhombus window which achieves a satisfactory result on the application of fault identification. Research shows that: 1) the attributes extracted by rotating rhombus have better ability of direction identification, and it is particularly suit to identify the fault and fracture zone; 2) the attribute extracted by rotating rhombus its major to minor axis ratio is 5:2 has the best resolution; 3) our method has a good noise immunity, which can extract accurate direction attribute if the SNR is greater than 1, which can completely fulfill the require of data interpretation. Two real seismic data application examples show that this method can better detect the fault and shattered fault zone and discriminate the scope of fault zone.
