MULTI-COMPONENTS SEISMIC JOINT ATTRIBUTES ANALYSIS AND HYDROCARBON IDENTIFICATION IN TERRESTRIAL INTERBEDDED THIN RESERVOIR
Qizhen Du · Marine Geology Frontiers · 2012
Multi-components seismic survey receives P-wave and P-SV converted wave data simultaneously,and the seismic information received are doubled.P-wave and P-SV converted wave have different sensitivity to lithology and fluid that causes seismic attribute anomalies.Therefore,by studying the joint attributes of P-wave and P-SV wave,ambiguity in simple P-wave interpretation will be reduced,and more reliable litholgy and fluid information obtained.Using Multi-components forward modeling of seismic data,the paper discussed the feasibility and reliability of hydrocarbon identification by multi-components seismic joint attributes in terrestrial interbedded thin reservoir in the Ken 71 area of the Shengli oilfield.The results are proved useful for oil and gas prediction.
