垦东北地区古近系油气输导体系特征
Characteristics of the Paleocene Oil and Gas Transmission System in North Kengdong Area
摘要
Abstract
To address the problems such as the characteristics of the Paleocene oil and gas transmission system and its control role on oil and gas distribution in north Kendong Area,based on geological,seismic and well-logging data,we analyzed the development characteristics of the transmission elements and evaluated and classified their transmission capacity and combination types,so as to clarify the relationship between the transmission system and the oil and gas distribution.The study shows that oil source faults with strong activity during the reservoir formation period and laterally connected sand body or unconformable carrier bed are important channels for oil and gas trans-mission;when the fault-sand body/unconformable lateral flow coefficient is greater than the lower-limit value,the oil/gas may be laterally charged along the faults to the sand body/unconformable carrier bed.Five transmission sys-tems have been classified according to the characteristics of the combination of transmission elements and transmis-sion capacity,of which type Ⅰ,type Ⅱ,type Ⅲ have strong transmission capacity,and type Ⅳ,type Ⅴ have weak transmission capacity,resulting in the multilayered system was enriched in the middle of the north Kendong Area,and the oil and gas were deeply gathered in the east and west.The study results have certain reference signifi-cance for the next oil and gas exploration work in north Kendong Area.关键词
