| 摘 要： | 川西坳陷碎屑岩远源气藏主要为构造与岩性的复合圈闭,其构造形态及作为输导条件的断裂所处构造位置和储集岩展布三者之间的配置控制着圈闭的有效性和气藏的大小,只有储集岩以其低部位与油气运移通道(断裂)相接,且储集岩在其上倾方向能构成构造或岩性封闭,其圈闭才有效;否则,圈闭无效。

| Abstract: | Most of the second distal clastic gas pools in the West Sichuan depression are the composite structural and lithologic traps. The efficiency and sizes of the gas pools are controlled by the combined factors of structural morphology, tectonic position of faults and distribution of the reservoir rocks. Only when the reservoir rocks are connected with the faults as the channels of gas migration at the lower levels, or constitute the structural and/or lithologic seals along their dip direction, may the traps become effective. |
