| 摘 要： | 梨树地区是发育在前中生代变质基底之上于晚侏罗-中白垩世形成的多层叠置的断-坳型盆地。十屋断陷中生界总厚近10000m。五家子组为主要烃源岩,泉头组砂岩为主要储集层,长期在杨大城子古隆起控制下形成的各类圈闭为重要的油气勘探靶区。

GEOLOGICAL CONDITION FOR FORMATION OF HYDROCARBON POOLS IN LISHU AREA |

| Abstract: | Lishu area in southern Songliao Basin is a multi-overlapped fault-depressed basin de-veloped upon the Premesozoic metalmorphic basement during Late Jurassic-Middle Creta-ceous.The total thickness of Mesozoic strata in Shiwu fault-depression is about 10000m.The Wujiazi Formation is an important oil-gas source rock.The Quanto sandstone reser-voir developed in depression stage is the main deep-generated low-reserved reservoir. The distribution and thermal evolution of the source rock and two structural move-ments(late Denglouku and Nenjiang stages)controlled hydrocarbon distribution.The steep slope belt in the north of Shiwu faulted-depression is the principal area for hydro-carbon accumulation.From deep depression area to upwelling area,the present area could be divided into three semi-circle hydrocarbon accumulating belts such as Houwujia-hu gas belt,Xiaowujiazi oil-gas belt,Yangdachengzi thick oil belt. |
