| 摘 要： | 下二叠统茅口组是四川盆地东南部海相油气勘探的重点层位之一,其主要储集空间为茅口组顶部灰岩中岩溶缝洞体。通过对已知典型气藏的解剖和地震地质模拟,总结了4种岩溶缝洞体的地震响应特征;并以此为依据,在该区地震剖面上寻找和识别了一批反映岩溶缝洞体的地震异常体。

| Abstract: | Maokou Formation of the lower Permian system is one of the most important oil and gas exploration layers of marine fades in the southeast of Sichuan Basin. Its main gas--bearing body is karst cave--cleft system in the limestone on the top of Maokou Formation. By analyzing the known typical gas reservoirs and seismic--geological modeling, this paper sums up four kinds of seismic response characteristics of cave--cleft system. Based on the seismic response characteristics, a batch of seismic abnormalities reflecting cave--cleft system are found and identified in the seismic sections of this area. |
