四川盆地二、三叠系礁滩资源潜力分析

Analysis on the resource potential of The Triassic Reef and Shoal in Sichuan Basin

盆地二、三叠系礁滩勘探领域已成为进行拓展深化勘探的重点层系之一,探明程度低(仅为14.5%),目前进一步明确礁滩的构造沉积格局,分布特点,优选有利勘探区带等方面存在重要的研究价值。通过对四川盆地二、三叠系礁滩的构造-沉积格局,古构造环境,烃源条件的分析,找出了礁滩展布的有利相带,证实了四川盆地二、三叠系礁滩具有广阔的资源潜力和勘探前景,并优选出了三个有利勘探区带。

The reef-shoal exploration field of the Permian and Triassic system in the basin has become one of the key strata for further exploration and deepening,with a low degree of exploration(only 14.5%).At present,it is of great research value to further clarify the tectonic and sedimentary pattern,distribution characteristics and optimal exploration zones of the reef-shoal.By analyzing the structure-sedimentary pattern,paleotectonic environment and hydrocarbon source conditions of the Permian and Triassic reef shoals in Sichuan basin,the favorable facies belts for spreading the reef shoals have been found out,and it has been proved that the Permian and Triassic reef shoals in Sichuan basin have broad resource potential and exploration prospect,and three favorable exploration zones have been optimized.
