摘要
三盛玉一利发胜地区是研究松辽盆地南部天然气成藏的一个重地区,该地区天然气成藏特点是周边断陷天然气通过不整合面和控盆断裂作长距离运移到本区聚集成藏。区内存在两期成藏、两种成藏模式,一是受早期构造控制,晚期构造叠加形成的早期成藏模式,二是由晚期构造控制的晚期成藏模式。早期构造比晚期构造更有利于天然气成藏。
The mechanism of natural gas pool formation in Sanshengyu----Lifasheng area is that the natural gas which is gen--erated in peripheral fault sag migrate to this area through unconformity or basin controlling faults. There exist two stages of pool formation and two kinds of pool formation models ,one is early stage pool formation mode which is formed by the control of early stage structure and by the superimposition of late stage structure, the other is t ate stage pool formation model which is controlled by ! ate stage structure. Early stage structure is more favorable than late stage one in natural gas pool formation. The western region of the area is primary exploration region in which early stage structure is to be found.
