Structural Features And Exploration Direction Analysis In Fuyang Area

The use of seismic data in Fuyang area and the new deployment of new seismic research results,combined with drilling data,starting from the characteristics of regional tectonic evolution analysis,clear features,the spatial distribution of active faults,straighten out the relationship between the fracture combination of three,establish the structural interpretation model,combing the development structure in the interpretation mode under the guidance of discovery and implementation of trap in the implementation,five aspects of research have been achieved.(1)Analysts believe that Fuyang area has undergone Indosinian thrust nappe,Yanshan strike slip and tension,the Himalayan tectonic movement Zhang Heruo strong pull extrusion three,in effect three stages of tectonic movement,which was composed of Paleozoic cratonic basin,early Cretaceous strike slip basin,Paleogene rift basin.In the sedimentary basin in Neogene Quaternary depression superimposed basin.(2)The characteristics of tectonic evolution in Fuyang area are studied,and the fault strike,fault distance,fault activity time and fault boundary characteristics of 12 main faults are counted.(3)According to the characteristics of fault development,six tectonic styles of Indosinian simple thrust,imbricate thrust and faulted fold,and strong tension,weak compression and positive inversion in Himalayan period are established.Under the guidance of tectonic interpretation model,the relationship between regional tectonic framework and fault assemblage has been straightened out.25 Tc traps have been found,and the trap area is131.7km~2.Five tectonic belts have been divided according to the similarity of Trap Geological conditions.(4)Comprehensive evaluation of transportation conditions,five tectonic belt,migration and accumulation of oil and gas preservation conditions,set up the logic that the fault disk area,No.1 ancient temple to fault area,north of the Feihe River Dawangzhuang fault rising plate for oil and gas migration and accumulation of I favorable area;Zhao Miao fault rise disc,Lu Cun area poly class II favorable area for oil and gas.(5)The ancient city of Li Ji submitted tectonic traps,Feihe River tectonic belt Feihe River No.2 two favorable traps.
