3D Seismic Data Interpretation And Structure Research In Liuxi

Raoyang sag is in the middle of Jizhong depression,has witnessed more than 40 years of exploration history since 1964,exploration area is about 6300km2,is one of the most richest in Jizhong depression and the remaining resources are still relatively large.At early stage and middle stage of the history,structural traps were exploration targets and most of them were unveiled to be commercial reserves.There are many structural belts in Raoyang sag,and liuxi structural belt is in the middle of Raoyang sag,west to Dawangzhuang East fault,and north to Suning structural belt. East to Xicheng syncline,and South to Liuchu structural belt,exploration area is about 400km~2 .In this paper,we use the Liuxi structural belt of Raoyang sag as the research object,through making the 3D seismic data interpretation to the datum horizon of Liuxi,analysis the fault structure,developmental stages of fault,structure style of step-fault zone,development history,confirm the beneficial zone,and make a description of beneficial traps.Through the research of the subject we can believe that the main reservoir type is fault block, and combined the data of developed wells to analysis the factor of reservoir,implementing the key target areas.
