This thesis, sequence stratigraphy , structural geology , reservoir sedimentology , and the volcanic rocks in theory as a guide, make full use of the Fengle three-dimensional seismic data , petrophysical analysis of data , logging data , applications constrained sparse spike inversion Yingcheng reservoir prediction , comprehensive description of the distribution of volcanic reservoirs range , occurrence and distribution of reservoir parameters , fine to characterize interwell gas water for distribution relationship , the type of gas reservoir analysis and comprehensive evaluation . Cycle and subcycle segmentation Yingcheng strata based on carry out carry out the fine seismic the geologic horizons calibration , calibration based on layers and on comparative interpretation of faults , from the base to the top surface of Yingcheng Formation of structural shape of the top surface has a good inheritance , and the overall performance of the South than in the north , east and west wings high middle and low , central tectonic belt along the fracture Xu in the development of a NW direction . Tectonic trend surface analysis technology , three-dimensional body sectioning technique , seismic coherence analysis technology , volcanic rock thickness analysis combined drilling and logging data to characterize volcanic rocks institutions , the study area is mainly fissure - center - duplex eruption , on the plane , along the NNW toward the West Song fracture was oriented distributed clusters of individual volcanic edifice scattered along the associated fracture . Using seismic facies waveform classification combined with a single well volcanic rock facies derived volcanic lithofacies distribution . Wave impedance inversion density inversion distribution characteristics of volcanic reservoirs in the studies , the density of volcanic reservoirs in general in 2.31g/cm3-2.53 g/cm3 wave impedance value 9900m.g / s . the cm3 -14500m.g/s.cm3, dense layer is higher than the value lower than the value sedimentary rocks . Finally, a comprehensive evaluation of the reservoir , and to establish the appropriate geological model , to determine the favorable zones is the target preferred , gas field development program designed to provide basic information and gas reservoir fine description of achievements .
