Abstract
The Zengdan Dengying formation gas reservoir in Gaoshiti Moxi block of Sichuan basin is a large deep carbonate gas reservoir. Affected by typical karst, it has features of low porosity and low permeability, strong heterogeneity, diversified holes, complex seepage law, and great difficulty in exact gas reservoir description, which have seriously restricted optimization of gas reservoir and development of technical countermeasures. To solve those problems, this paper has formed dolomite weathering crust karst zoning description method with core description and diagenesis interpretation; forms quantitative millimeter-level fracture-cavity collocation and prediction with digital technology of core description and seismic interpretation technology;forms favorable development zone evaluation and optimization with triple media reservoir well test diagnosis. These techniques have provided a solid technical support for the favorable zone selection and policy formulation.关键词
