摘要:

胜利油区老河口油田桩106井区馆陶组砂层组主要包括河道、堤岸、泛滥平原、废弃河道4种沉积亚相。主力含油层为上第三系馆陶组上亚段曲流河沉积的河道砂体。该区周围被富生油凹陷包围,断层对该区上第三系油气的运移和聚集起到了重要的控制作用。通过大、小断层的连接,油气沿断面和储集层作垂向和横向交替运移,形成网毯状油气运聚模式。丰富的油源、优越的油气运聚条件以及良好的储盖组合在馆陶组形成以岩性油藏、岩性-构造油藏为主的隐蔽油气藏。油气藏自南向北具有含油层系逐渐变多、变深,含油性能逐渐变好的特点。

Abstract:

Sandbodies of Guantao Fm in Zhuang 106 wellblock in Laohekou oilfield are mainly of channel, bank, flood plain and abandoned channel subfacies. The channel sandbodies in the upper Guantao Fm deposited in meandering river environment are the main oil-bearing formations. Migration and accumulation of the Neocene hydrocarbons in the study area, surrounded by sags with rich source rocks, were controlled by faults. The large and small faults were connected into a network. Hydrocarbons alternatively migrated along the fault planes in vertical direction and along the reservoirs in lateral direction, forming a network-blanket migration and accumulation pattern. The rich source rocks, favorable migration and accumulation conditions, as well as good reservoir-cap rock combinations have led to the formation of subtle oil and gas reservoirs dominated by lithologic and lithologic-structural reservoirs. From south to north, the number of oil-bearing layers gradually increases, their depths enlarge and the oil-bearing properties get better.

Key words: channel sand, geologic feature, reservoir type, control factor, Laohekou oilfield
