基于地震解释和前人研究资料,从分析安顺凹陷油气成藏类型入手,探讨了研究区潜在成藏类型、成藏特征及勘探潜力,分析认为:安顺凹陷下组合存在的成藏类型主要有“麻江古油藏”型油气藏;上组合存在的成藏类型主要有“礁滩”型和“不整合面或风化壳”型油气藏组合.同时,安顺凹陷烃源条件较好,油源丰富,且是油气运移长期指向区;发育良好的储盖层,具有区域性保存条件.指出,普定复向斜带是安顺凹陷最有利勘探区带.

The potential petroleum accumulation types, features and forecasts of the Anshun Sag in the Southern Guizhou Depression have been discussed based on seismic interpretations and previous studies. In the lower for-mations of the sag, “Majiang paleo-reservoirs” have been found. In the upper formation, there exist “reef-flat”and “unconformity surface or regolith” reservoirs. Meanwhile, source rocks are well-developed and the sag is the long-term target zone for hydrocarbon migration. Good cap rocks provide good regional hydrocarbon preservation conditions. The Puding synclinorium is the most favorable exploration target in the Anshun Sag.
