摘要：四川金地高石梯-磨溪区块震旦系灯影组气蓝为典型的大型深层碳酸盐岩气慧，受岩溶等国素影哨，储层低孔低渗特征明显，非灼质性强、孔洞搭配多样、渗流规律复杂，气蔗精确描述难度大，产重制约了气藏开发有利区的优选和开发技术对策的制定。为解决此类气藏精确描述的难题，运用岩心描述和成岩解释形成了自云岩风化壳岩溶分带描述方法：运用数字岩心描述技术承融合地囊解释技术形成了量化毫米级缝调搭配和预测方法：运用三重介质储层试井诊断储层渗透性、形成岩溶性碳酸盐岩气藏开发有利区评价及优选技术。这套深层岩溶碳酸盐岩描述技术为该类气的开发政策提供了整套技术体系。

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 pemeability, strong heterogeneity, diversified holes, complex seepage law, and great dificulty 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; foms 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
