Abstract


Volcanic reservoirs due Xujiaweizi deeply buried , the spatial distribution of the shape changing fast phase transition , the complexity of the physical changes , and constructed a large range , lithology, electrical characteristics corresponding obvious deep exploratory well , resulting in the volcanic reservoirs in accurate prediction difficult , the comprehensive utilization of the theory of multiple disciplines , a variety of technical methods for reservoir prediction has become inevitable . Logging crossplot technology lithology identification , the imaging logging can identify the type of the reservoir and to determine the characteristics of the volcanic strata tendency inclination occurrence . The use of a coherent body of technical faults and the spatial distribution of micro - fracture , abnormal geological structure and lithology of the overall spatial distribution characteristics . Earthquake logging comprehensive constrained inversion draw high - resolution wave impedance inversion profile . Comprehensive logging , geological and seismic data , the use of coherence cube technology, the surface slice three-dimensional display technology seismic data fine structure portrayed . Analysis based on a large number of seismic sections and horizontal slices basic seismic characteristics of volcanic rocks , and the formation of the volcanic rocks of basic recognition mode . Based on seismic and geological data , comprehensive utilization of lithology , facies analysis , thickness analysis , seismic section analysis to find the crater with its main area of development .
