| 摘 要： | 四川盆地开江地区石炭系黄龙组（C2hl）发育类型多样的复合圈闭，蕴含丰富的天然气资源，识别其圈闭类型，对复合圈闭进行评价，对下一步勘探具有重要意义。分析发现，该区发育的复合圈闭主要为地层-构造复合圈闭，圈闭类型多样，是黄龙组进一步勘探的主要对象。复合圈闭在地层上多分布于沿开江-梁平C2hl残余厚度介于10～50 m的地区；在沉积相上集中分布在潮间带颗粒滩相、成岩期交代成因的埋藏白云岩发育区；在构造上多分布于构造高部位隆起缺失带附近等。在古隆起构造高部位C2hl强剥蚀区及靠近剥蚀边界的地层厚度薄带中识别出一批潜在地层-构造复合圈闭。根据圈闭面积、闭合度、厚度、埋藏深度、圈闭可靠程度等指标，利用综合评价方法，将该区复合圈闭分为3类，Ⅰ类圈闭依次为：TLP复合圈闭、WSK复合圈闭、BYSB复合圈闭和BYS复合圈闭；Ⅱ类圈闭依次为：Y’A复合圈闭、SZS复合圈闭和BYSN复合圈闭；Ⅲ类圈闭为NMC复合圈闭。

| Abstract: | Various combination traps are developed in the Carboniferous Huanglong Formation(C2hl) where abundant natural gas resources accumulate.Identification and evaluation of these combination traps are of great significance to future exploration.The combination traps in the study area are dominated by stratigraphic-structural combination traps which are the major targets of exploration in the Huanglong Formation.Stratigraphically,these combination traps are mostly distributed in Kaijiang-Liangping area where the ... |
