摘要

Duvernay组与Leduc组和Grosmont组的浅海台地碳酸盐岩同时形成富有机质的盆地泥岩。历史上,Duvernay被认为是常规油气生产的主要烃源岩,但与世界上其他烃源岩层段一样,Duvernay已发展成为横跨加拿大阿尔伯塔省的非常规页岩储层。Duvernay组的分布被称为Rimbey-Meadowbrook走向的狭窄线状Leduc组礁杂岩划分为西部和东部页岩盆地。自2011年以来,开发主要集中在西部页岩盆地,但热成熟度趋势表明,东部页岩盆地南部的页岩储层开发潜力较大。本研究描述了沉积学和地层对Duvernay储层潜力的控制,以确定东页岩盆地内的开发“甜点”。在该研究中绘制的Duvernay地质属性包括:油热成熟度、厚的受限盆地相组合产状(至少5-10m厚)、高平均TOC值(大于2.0 wt.%)和高净碳酸盐厚度(大于40m)。地质属性是水平井生产潜力的预测指标,其共产分布表明了东页岩盆地南部扩大开发的潜力。

Controls on East Shale Basin reservoir distribution within the Upper Devonian Duvernay Formation, Western Canada Sedimentary Basin
The Duvernay Formation accumulated as an organic-rich basinal mudrock concurrent with shallow marine platform carbonates of the Leduc and Grosmont formations. Historically classified as a major source rock to conventional hydrocarbon production, the Duvernay evolved into an unconventional shale reservoir across Alberta, Canada much like other source rock intervals worldwide. Distributions of the Duvernay Formation are partitioned into the West and East Shale basins by a narrow, linear Leduc Formation reef complex known as the Rimbey-Meadowbrook trend. Since 2011, development has focused on the West Shale Basin, but thermal maturity trends suggest the potential for expanded shale reservoir development within the southern portion of the East Shale Basin. This study characterizes sedimentologic and stratigraphic controls on Duvernay reservoir potential to identify development “sweet spots” within the East Shale Basin. Duvernay geologic attributes mapped within this study include: oil thermal maturity, thick restricted basin facies association occurrence (at least 5-10m thick), high average TOC values (greater than 2.0 wt.%), and high net carbonate thickness (greater than 40m). The geologic attributes are predictive of production potential within horizontal wells, and the distribution of their co-occurrence suggests the potential for expanded development within the southern portion of the East Shale Basin.
