By using ful|y of drilling,seismic,gravity magnetic and electronic and related analysis assay data,on the basis of the theory, technology and method of structural geology,tectonic dynamics,sequence stratigraphy,petroleum geology,petroleum basin analysis,geophysical data processing and interpretation,structure value simulation,distinguish and interpret the characters of tense-shearing structure.By describing the characters of the geometry and kinematics of tense-shearing system,carried out the numerical simulation of the tectonic stress field and formation mechanism,summarized the developing and evolving pattern of the tense-shearing geological structure,researched on the trap types and distributing features under the condition of the tense-shearing stress field,make clear that the control effect of tense-shearing structure for traps.According to distinguishing the internal structure characters of fault zone,established the model of internal structure in fault zone and summarized the types of it.By studying on the translocation and sealing of fault,researched on the oil and gas advantage migration path and the direction under the condition of the tense-shearing stress field,established the model of oil and gas migration and accumulation in study area,on this basis,determined the next exploration direction of the study area,optimum selected the beneficial exploration zone,acquired the well exploration benefits.
