OIL AND GAS GATHERING RULE IN THE SEQUENCE STRITAGRAPHIC FRAME OF FAULT DEPRESSION LACUSTRINE BASIN——AN EXAMPLE FROM SONGLIAO BASIN

GUO Wei, LIU Zhao jun,DONG Qing shui,FANG Shi (College of Earth Sciences,Jilin University, Changchun 130061,China)  
The early stage fault depression of lacustrine basin style study shows that there are two types and four modes of structural style. They are half graben with compensate fault and without compensate fault, and complex half graben with compensate fault and without compensate fault. An integrated sequence comes into being a suit of regional assemblage of source rock, reservoir and caprock. The main source rock is the dense tract between the TST to the HST, and it is also the better caprock. The favorable reservoir often developed in the bottom of the LST and TST, the top of the HST and in the RST. There are four types of the regional source reservoir caprock assemblage, such as top source bottom reservoir, top reservoir bottom source, sid source side reservoir and itself source itself reservoir. Lithological oil and gas pool developed in every sytem tract. Moreover, the structural oil pool is the main type of the HST and the unconformity oil pool can be found in the RST.
