The lacustrine shale of the Upper Cretaceous Qingshankou Formation is principal prospective unconventional target lithology, acting as source, reservoir, and seal. Lithofacies associated storage capacity are two significant factors in oil prospectivity. This paper describes an investigation lower based on detailed description analysis cores, lithofacies characteristics, depositional setting, stacking patterns. Seven recognized organic matter content, sedimentary structure, mineralogy, all...
The pore structure and oil content of shales have an important influence on the mobility enrichment. In this study, lacustrine shale samples from Qingshankou Formation (Q1) Songliao Basin were selected. TOC, pyrolysis, XRD nitrogen adsorption performed original extracted samples. Then mineral composition organic matter (OM) development nano-scale pore, phase states analyzed. Q1 can be sub-divided into three types according to isotherm characteristics. Type A are characterized by high kerogen...
Enhancing our understanding of the excess adsorption capacity in shale gas reservoirs is paramount for accurately predicting production capabilities and refining extraction processes. A significant factor this calculation accessible volume, which can only be measured indirectly using helium as a proxy. In study, hybrid grand canonical Monte Carlo/molecular dynamics (GCMC/MD) simulations were employed to scrutinize volume quantify capacities various gases kerogen matrices, characterized by...
The behavior of oil and water in tight rocks can change the distribution or pores, which affects production crude oil. Nuclear Magnetic Resonance (NMR) method is an effective non-destructive tool for evaluating with comparison analysis both quantitatively qualitatively. In our study, 20 MHz NMR Relaxometry used as a key technique to study changes behaviors Chinese lacustrine Qingshankou shales under different saturated states (imbibition evaporation without pressure). results show that...
Organic matter (OM) hosted pores are crucial for the storage and migration of petroleum in shale reservoirs. Thermal maturity macerals type important factors controlling development therein. In this study, six lacustrine samples with different thermal maturities from first member Qingshankou Formation Songliao Basin, which vitrinite reflectance (Ro) ranging 0.58% to 1.43%, were selected a comparative analysis. Scanning electron microscopy (SEM) reflected light combined investigate organic...
Describing the organic-inorganic pore evolution influenced by mineral composition is crucial for characterizing shale oil storage capacity and flow in shale, it also helps predict sequestered CO2. Using laboratory pyrolysis experiments to artificially mature samples at relatively high temperatures short times, this study compares a series of natural with different thermal maturations, which can better reflect real underground evolution. A total 30 shales spanning from low maturity were...
As an unconventional resource, shale reservoirs recently have attracted considerable attention in the petroleum industry. Shale plays are highly heterogenous vertically and laterally characterized by rapid changes mineral composition. Thus, identification of dominant lithofacies is a key issue development oil gas reservoirs. In this study, various existing section as target unit Qingshankou Formation divided based on organic matter content, sedimentary structure, To delineate electrofacies...
On the basis of sorting out current understanding solid bitumen (SB) in shales and taking organic-rich first member Cretaceous Qingshankou Formation Songliao Basin as an example, definition, classification, occurrence evolution path SB are systemtically studied, indicative significance reflectance (Rob) on maturity its influence development reservoir space discussed summarized. The results show that difference primary maceral types is primarily responsible for different paths SB. Most...
The Lucaogou Formation (Fm) in the Jimusaer depression is first large-scale development of a terrigenous clastic sedimentary shale oil reservoir China. Nearly one billion tons resources have been discovered. However, current exploration and concentrated eastern part sag. limited geological understanding western area has restricted prediction "sweet spots" for oil. To help rectify this, we studied petrology, geochemistry, content, pore properties second member (Mbr) Fm (P2l12) typical well...
摘要: 截止目前古龙凹陷页岩油的开发已见成效,总结古龙页岩油富集的地质条件对下一步的勘探开发工作尤为重要.对当前古龙页岩油基础地质特征及勘探成果进行了梳理总结,归纳了规模见产可能面临的科学技术问题,并探讨了下一步科研攻关方向.松辽盆地北部青山口组一段页岩具有机质丰度高(TOC为2.0%~3.0%,平均2.7%)、类型好(以Ⅰ型干酪根为主,生烃母质为层状藻类体)、成熟度高(Ro为1.20%~1.67%)、黏土矿物含量高(大于35%)等典型特征.受益于较高的地温梯度,古龙凹陷青一段有机质达到高成熟阶段,油质轻(地面密度小于0.8 g/cm3)、气油比高(大于50 m3/m3),具备高熟页岩油规模开发潜力.页岩油甜点评价标准的厘定、单井EUR预测存在不确定性及规模效益开发配套技术欠缺是古龙页岩油勘探开发目前面临的主要挑战.黏土矿物对油水赋存状态乃至含油饱和度的影响、复合润湿性对压裂液渗吸置换效率的控制等陆相页岩油特有机理研究的突破,将会推动国家级开发示范区产油目标的快速实现,并有望在轻质油带开发基础上向稀油带扩大古龙页岩油勘探开发成果. 关键词: 松辽盆地 / 青山口组 陆相页岩油...
Large volumes of heavy oil were distributed in the pre-Jurassic strata Tainan sag, Turpan Hami Basin, China. The geochemical characteristics and origins are great significance to future exploration region. In this study, we classified crude using data on its physical properties, group composition, biomarker compounds. Further, distribution different types horizontal vertical directions clarified.
