Abstract

The dolomite reservoir,with huge prospecting potential,is widespread in Sichuan basin.Due to various reasons,the prediction of dolomiet reservoir is extremely difficult.In order to guide reservoir prediction,this paper introduces forward modeling to study the seismic response of dolomite reservoir.The seismic response of Permian Qixia dolomite reservoir is not clear.In order to clarify the seismic response characteristics,the authors constructed different forward models in combination with the situation of drilling.The analysis of forward modeling results shows that,on the one hand,reservoir seismic response is weak wave reflection when the underlying strata are high-speed formation and,on the other hand,the response characteristics of the reservoir are influenced by the underlying strata,featured by trough reflection,but still show the weak wave reflection after eliminating the influence of the underlying strata of low speed formation.Meanwhile,the authors combined seismic attributes and high resolution seismic inversion to predict dolomite reservoir.The forward modeling provides a basis for studying seismic response characteristics of dolomite reservoirs and also serves as a means for further study of the dolomite reservoir.

Key words： dolomite reservoir seismic response forward modeling
