In recent years, oil and gas drilling has shown that high volcanic natural reservoirs. Volcanic reservoirs has become one of the foreign and domestic oil and gas exploration in new areas, by the oil and gas exploration sector attention. But application seismic interpretation recognition deep volcanic reservoir is a worldwide problem. In conclusion, the predecessor to this thesis research material on the basis of the Fenglenan area for fine interpretation of the deep structure, significance lies in the Fenglenan area of Yingcheng group mainly typical volcanic formation of volcanic rock formations, including structural interpretation currently is a relatively new field.This thesis to sequence stratigraphy for guidance, the comprehensive application of the drilling, well logging data, seismic data, on the basis of fine structural interpretation by earthquake, establish best underground geological objective laws of 3D geological models, the final scientific and rational analysis the Fenglenan area of the distribution of volcanic structures. The Xunan sub-depression of Fenglenan area can divide up Step-fault Zone in Western, deep zone in Central and Slope Belt that are sunk with three secondary structure elements, tectonic evolution has a good inheritance. Division of tectonic zone of fracture and its associated faults have synsedimentary characteristics, thereby advancing the deep structure fine interpretation of further development.For three-dimensional seismic Fenglenan area, on the General explain need three-dimensional seismic interpretation on the basis of the production of fine synthetic seismogram calibration application layer; implementation of a coherent technology accurate fault distribution; at the same time, correlation by well-to-seismic integration technology promotes structural interpretation of seismic data, as well as logging data comparison provides a good basis, generally highlight of delicate nature, accuracy and objectivity, to next reservoir evaluation and provided a basis for investment in development.The thesis research results will play arrive at certain role to development of one field driving this , the develop and broader application studying result explains the technology going a step further to deep lava at the same time has important value.This thesis research results in advancing the field of development will play a role, at the same time research results for deep volcanic interpretation of further development and greater value with important.
