【摘要】：綜合運(yùn)用巖心觀察、薄片分析、巖石物性測(cè)試、同位素測(cè)試以及試油、試采結(jié)果分析等方法,對(duì)濟(jì)陽(yáng)坳陷東營(yíng)凹陷古近系深層復(fù)雜儲(chǔ)集體優(yōu)質(zhì)儲(chǔ)層形成機(jī)理與油氣成藏過(guò)程進(jìn)行了研究。研究表明,酸-堿流體交替溶蝕作用形成的次生孔隙在一定程度上改善了深層局部?jī)?chǔ)層物性,是深層優(yōu)質(zhì)儲(chǔ)層形成的關(guān)鍵。深層不同層序沉積物原始組分、流體環(huán)境、源-儲(chǔ)配置等條件的不同,使優(yōu)質(zhì)儲(chǔ)層的形成機(jī)理存在差異。初始裂陷層序河流-沖積扇紅層優(yōu)質(zhì)儲(chǔ)層發(fā)育于堿性環(huán)境,且與烴源巖側(cè)向接觸,不僅發(fā)生大量的長(zhǎng)石和碳酸鹽巖溶蝕,石英也發(fā)生強(qiáng)烈的溶蝕。擴(kuò)展裂陷層序陡坡扇三角洲、水下扇砂礫巖優(yōu)質(zhì)儲(chǔ)層與烴源巖呈指狀接觸,且通過(guò)控盆斷層與深部堿性流體溝通,主要表現(xiàn)為長(zhǎng)石和碳酸鹽巖溶蝕,石英只是局部少量溶蝕。擴(kuò)展裂陷層序?yàn)〾紊昂蜐岱e巖優(yōu)質(zhì)儲(chǔ)層大部分分布于烴源巖中,主要表現(xiàn)為長(zhǎng)石和碳酸鹽巖的溶蝕。緩坡斷階帶處于流體優(yōu)勢(shì)運(yùn)移通道,與烴源巖對(duì)接的紅層優(yōu)質(zhì)儲(chǔ)集有利于成藏。陡坡帶扇根遮擋的扇中砂礫巖優(yōu)質(zhì)儲(chǔ)層有利于油氣成藏。處于生烴增壓烴源巖中,發(fā)生成巖耗水的灘壩砂和濁積巖優(yōu)質(zhì)儲(chǔ)層有利于成藏。
[Abstract]:Comprehensive use of core observation, thin slice analysis, rock physical properties testing, isotopic testing and oil testing, production test results analysis, etc. The formation mechanism and hydrocarbon accumulation process of high quality reservoirs in Paleogene deep layer in Dongying depression of Jiyang depression were studied. The results show that the secondary pores formed by alternate dissolution of acid-base fluids improve the physical properties of deep local reservoirs to a certain extent and are the key to the formation of deep high quality reservoirs. The formation mechanism of high quality reservoirs is different due to the difference of the original composition, fluid environment, source-reservoir configuration and so on. The primary rifting sequence fluvial and alluvial fan red beds developed in alkaline environment and have lateral contact with source rocks. Not only a large number of feldspar and carbonate dissolution occurred but also strong dissolution occurred in quartz. The spreading rifting sequence steep slope fan delta, the high quality reservoir of underwater fan sand gravel and the source rock are in finger contact, and communicate with the deep alkaline fluid by controlling the basin fault, the main manifestation is feldspar and carbonate rock dissolution, quartz is only a small amount of local dissolution. The high quality reservoirs of extended rifting sequence beach bar sand and turbidite are mostly distributed in source rocks, mainly represented by dissolution of feldspar and carbonate rocks. The gentle slope fault terrace is located in the dominant channel of fluid migration, and the red reservoir interfacing with the source rock is favorable for reservoir formation. The high quality sandstone and conglomerate reservoir with fan root occlusion in steep slope zone is favorable for oil and gas accumulation. In hydrocarbon-generating pressurized source rocks, the high quality reservoir of diagenetic and water-consuming beach bar sand and turbidite is favorable for reservoir formation.
