松辽盆地太东斜坡区葡萄花油层油水分布规律及主控因素
Oil distribution rule and main controlling factors of Putaohua reservoir in Taidong slope, Song-liao basin
摘要
Abstract
Taidong slope area is the single slope where Daqing placanticline plunge to Sanzhao sag in Songliao basin. Using data as core, logging, and seism, we study reservoir types and hydrocarbon distribution rule in Putaohua reservoir and get the following conclusions: The slope area oil layers are divided by four nearly north-south trending fault zone in plane and have the feature of east-west zoning. Because the oil source outside the source area is insufficient and the east-to-west migration trending, oil-bearing in single fault terrace zone became worse gradually from east to west. Controlled by sedimentary evolution and advantage conducting channel, the vertical distribution of oil presents the feature of double peaks' and mainly distributed in central Putaohua reservoir. Under the background of SE tilt slope, the oil reservoir type is mainly fault-lithologic reservoir matched by nearly north-south trending fault and north-west trending channel sand body. According to the matching type of fault and channel sand body in single trap and the study of oil and water distribution rule, we think the accumulation mechanism is controlled by structural parts, high quality reservoir, fault seal ability and fault-sand matching style. That is to say, oil and gas accumulation parts are controlled by single 'fault terrace zone' high point, shallow water delta distributary channel and the river control sheet are high quality reservoirs, the lateral sealing ability of the fault affect hydrocarbon vertical enrichment height and plane 'complementary' characteristic, fault and single sand body matching style determine oil and gas enrichment position.关键词
