【摘要】 论文在调研大量国内外文献的基础上,依托中国四川盆地、塔里木盆地、鄂尔多斯盆地以及中国南方海相碳酸盐岩研究成果,创新提出了基于“障壁条件、古地理条件和坡度”三要素的障壁碳酸盐岩台地成因分类,将台地划分为两大类8种类型,即缓坡型障壁台地、陡坡型障壁台地、缓坡型障壁孤立台地、陡坡型障壁孤立台地、缓坡型无障壁台地、陡坡型无障壁台地、缓坡型无障壁孤立台地、陡坡型无障壁孤立台地,同时总结了每一种台地的基本特征,建立了相应的沉积模式和储层发育与分布模式。揭示了碳酸盐岩台地演化与宇宙万物演化一样,通常经历形成、鼎盛和衰亡三个阶段,这三个阶段与构造伸展沉降期、构造稳定期和构造抬升期一致,总的呈两种演化趋势：一种是由无障壁台地向障壁台地演化,最后因抬升暴露而终止；另一种是由无障壁台地向障壁台地演化,最后因快速沉降,台地被淹没而结束。论文最后以四川盆地长兴组潮湿气候陡坡障壁台地、飞仙关组干旱气候陡坡障壁台地和嘉陵江—雷口坡组干旱气候陡坡障壁台地为例,详细解剖了三种障壁台地的岩相古地理特征和储层分布规律,指出有利的勘探方向。总之,论文既有基础理论的创新又有实际应用效果,具有良好的学术价值和实用价值。更多还原

【Abstract】 Based on carbonate research results in Sichuan Basin, Tarim Basin, Ordos Basin and many literatures at home and abroad, the paper innovatively put forward a kind of genetic classification in carbonate platform which included three factors(barrier conditions, paleogeographic conditions and gradient).In this paper, platform was divided into two broad categories and eight sub-types, they are Barrier platform with gentle slope, Barrier platform with steep slope, Barrier isolation platform with gentle slope, Barrier isolation platform with steep slope, No barrier platform with gentle slope, No barrier platform with steep slope, No barrier isolation platform with gentle slope, No barrier isolation platform with steep slope. We summarized the basic characteristics of each kind of platform and established corresponding depositional mode, reservoir development and distribution pattern.We believe that evolution of carbonate platform just like the evolution of the universe, they Usually have three stages(formation, heyday and perish).these three stages are in accordance with tectonic stretch and subsidence, tectonic stable period and tectonic uplift period. There are two kinds of evolutionary trends:One is from No barrier platform evolved into Barrier platform, finally stopped due to uplift the exposure; The other is from No barrier platform evolved into Barrier platform, then platform was submerged because of rapid subsidence. The paper took Steep slope barrier platform with humid climate of Changxing Formation, Steep slope barrier platform with arid climate of Feixianguan Formation, Steep slope barrier platform with arid climate of Jialingjiang Formation and Leikoupo Formation in Sichuan basin as examples to detailedly dissected lithofacies paleographic characteristics and reservoir distribution rules of these three kinds of barrier platforms. The paper also pointed out advantageous exploration direction of three kinds of barrier platforms. Anyway the paper has innovation in Basic theory, actual application effect, academic and practical value.更多还原
