镶边性碳酸盐岩台地是我国主要的一种海相碳酸盐岩沉积类型。镶边性碳酸盐岩台地具有高能浅谈和礁带,向海侧为大陆坡折带,随着坡度降低进入盆地,是一种常见的浅水碳酸盐岩台地相。镶边性碳酸盐岩的沉积环境适宜生物繁殖,但不利于有机物质的储存,因而其生烃潜力较低,本文通过分析镶边性碳酸盐岩台地相的沉积特点,总结其生烃潜力以及其演化生烃特点,同时总结了碳酸盐岩储层的评价标准,并进一步指出镶边性岩台地相碳酸盐的源岩较难生成油源岩,而是主要作为气源岩。
Striped carbonate platform is a major marine carbonate sedimentary type in China. Striped carbonate platform with high energy shallow talk and reefs, to the sea side continental slope break zone, with the gradient into the basin, is a common shallow carbonate platform. The sedimentary environment of striped carbonate rocks is suitable for biological reproduction, but not conducive to the storage of organic matter, and therefore has a low potential for hydrocarbon generation. Based on the analysis of sedimentary characteristics of the striped carbonate platform, Potential and the evolution of hydrocarbon generation. At the same time, the evaluation criteria of carbonate reservoirs are summarized, and further it is pointed out that source rocks of banded carbonate rocks are more difficult to generate oil source rocks, but mainly as source rocks .
