The Eocene Shahejie Formation in the Zhanhua Sag of the Bohai Bay Basin has abundant shale oil resources. However， lacustrine shale is heterogeneous in mineralogy， sedimentary structure， organic matter， pore structure， paleoenvironment， and oil content. Therefore， the laminae assemblages are divided into laminated （lamina thickness of 0.1 m） types shale to investigate the core， X-ray diffraction （XRD）， thin section， field emission-scanning electron microscopy （FE-SEM）， mercury injection capillary pressure （MICP）， N2adsorption and geochemical experiments. The results show that the oil shale of Shahejie Formation in Zhanhua Sag is abundant in calcite. The TOC content ranges between 1.35% and 5.55%. Rock-Eval S1and S2values range from 0.30 to 2.56 mg/g and 0.97～15.47 mg/g， respectively. Variable kinds of nanopores， micropores， and microfractures are commonly observed. The connectivity of pores in laminated and layered shale samples is relatively better than massive shale. The massive shale was formed in a sedimentary environment with warm and humid climate， moderate salinity， weak reduction conditions， high productivity， and paleo-setting rate. Organic matter is derived from lower bacteria， algae， and terrigenous plants. Laminated and layered shale are formed in an arid and cold environment with high salinity， strong reducibility， low paleo-setting rate. Laminated shale is located on a gentle slope at the basin margin， which is the focus of shale oil exploration because of their higher hydrocarbon generation potential， reservoir quality， and advantaged horizontal fracturing conditions. The above results have implication for the sweet spots prediction in shales with similar geological setting.

地震属性蕴含大量储层信息,融合多种地震属性可提高储层预测精度。由于地下地质结构复杂、非均质性强,依据单一的地震属性融合方法难以精细刻画储层特征。为此,提出了一种基于Stacking集成学习的分频地震属性融合储层预测方法。该方法主要包括3个部分:①根据不同厚度储层的振幅与频率关系,利用多个频率的地震信息,降低地震属性的多解性;②联合相关性分析和无监督聚类技术优选地震属性,剔除冗余属性特征;③利用能够综合多个差异化模型优势的Stacking集成学习模型,融合不同频段的地震属性,提高地震属性的解释精度。将该方法用于渤海湾盆地埕岛油田,并使用线性公式定量分析法进一步评估Stacking模型的泛化效果。结果显示:与单类预测模型相比,Stacking模型的综合预测性能和可靠性均有显著提升;对应的地震属性融合结果高值区形态更加清晰,融合属性与砂体厚度的相关系数可达到0.92,这表明该方法具有良好的应用前景。

微观测试结果能反映很多油藏信息。目前关于微孔缝的镜下测试技术不断丰富,但仍缺少对微孔缝最全面的微观分析。为了便于对比各类测试技术,以济阳坳陷乐安油田草桥潜山区域为典型代表实例,先采用不同的精细微观专项测试技术对孔缝储集空间特征进行分析,具体包括微溶孔电子探针成分分析、扫描电镜、薄片和阴极发光测试等技术,然后总结了通过各种不同的微观测试技术观察到的现象及规律。具体结果和得出认识如下:通过电子探针成分分析技术,能够分辨出灰岩微溶孔内诸如有机质、方解石、黄铁矿、白云石、石膏等成分;薄片内可见灰岩含油段砾间砾内孔洞发育,溶蚀孔洞边部有轻微方解石化;通过扫描电镜分析,能够分辨出代表区块的白云岩结晶孔比灰岩溶蚀孔大两个以上数量级,能通过晶间孔或溶蚀孔推断岩石的脆性以及是否易于压裂;通过岩样阴极发光测试,能够区分出共有几期成分不同的孔洞充填物;通过扫描电镜和压汞都可以得到孔喉大小,比较两项技术,扫描电镜得到的是局部纳米级的孔喉直径,而压汞测试得到的是单块样品微米级孔喉半径。从应用对象来看,前者适合对应到矿物的孔喉,后者更适合开发区块的孔喉对比研究。

济阳坳陷是中国东部陆相断陷盆地的典型代表,新生界古近系沙河街组沉积一套巨厚的中—低成熟度页岩,能否有效开发动用其页岩油对于认识同类型页岩油潜力意义重大。通过50余口取心井系统的岩相、储集性及含油性研究与评价,对比国内外不同盆地页岩油特征差异发现,济阳页岩油咸化湖盆碳酸盐含量高,断陷盆地发育不同尺度裂缝,演化程度低导致储集空间以无机孔-缝为主,储集物性好但原油流动能力差。依据济阳页岩油地质特点,提出了以甜点立体综合评价、立体井网优化设计、立体压裂优化设计、全过程实施优化调控为核心的立体开发技术,建立了整体压裂同步投产、分批压裂逐步投产、立体滚动开发3种立体开发模式,矿场先导试验取得了突破,证实了中—低成熟度页岩油具有广阔的开发潜力。

Producing kaon mesons in heavy-ion collisions at beam energies below their threshold energy is an important way to investigate the properties of dense nuclear matter. In this study, based on the newly updated version of the ultrarelativistic quantum molecular dynamics model, we introduce the kaon-nucleon(KN) potential, including both the scalar and vector(also dubbed Lorentz-like)aspects. We revisit the influence of the KN potential on the collective flow of K+mesons produced in Au+Au collisions at Elab= 1.5 Ge V/nucleon and find that the contribution of the newly included Lorentz-like force is very important, particulary for describing the directed flow of K+. Finally, the corresponding Kao S data of both directed and elliptic flows can be simultaneously reproduced well.

济阳坳陷东营凹陷古近系沙四段上亚段、沙三段下亚段是胜利油田页岩油的主要分布层位,发育富灰型、混积型、富长英质型3种页岩储层类型,其中富灰型页岩最为发育。富灰型页岩中亮晶方解石纹层发育段具有良好的储集性、含油性、渗透性、可压性特征,在牛庄、民丰、利津等洼陷多口水平井获得峰值日产油超百吨的良好效果。利用普通薄片、阴极发光、包裹体分析、同位素地球化学分析以及氩离子抛光扫描电镜等测试手段,分析了纹层状亮晶方解石的成因机制及其储集意义。结果表明,纹层状亮晶方解石分为重结晶的晶粒方解石纹层和生排烃形成的纹层状亮晶方解石脉。重结晶的晶粒方解石纹层是湖泊自生沉淀的泥晶方解石纹层在早成岩阶段原地重结晶形成的,其形成过程与浅埋藏期硫酸盐细菌还原作用密切相关,方解石晶体呈粒状,形态不规则,纹层厚度稳定,分布连续;纹层状亮晶方解石脉的形成则与有机质热演化成熟时期的生排烃密切相关,有机酸溶解了页岩中的泥晶方解石形成富碳酸盐流体,这些流体在生烃压力的作用下顺纹层间裂缝运移后再次结晶沉淀形成方解石脉体,纹层相对较厚,呈透镜状,平面上断续分布。2种亮晶方解石纹层中广泛发育层间缝(层理缝)、晶间缝和晶间孔、溶蚀孔,宏孔占比高,连通性好。亮晶方解石纹层与富有机质泥质纹层呈“层偶状”频互层,构成富有机质纹层状亮晶泥质灰页岩、富有机质纹层状亮晶灰质泥页岩2种岩相类型,“源储”一体,页岩品质好,是济阳页岩油富灰型页岩中最为有利的岩相类型。
