为系统研究碱湖页岩中黏土矿物的发育特征及转化模式，并探究在碱湖沉积环境中黏土矿物发育情况，利用扫描电镜观察、X射线衍射分析等实验，对准噶尔盆地玛湖凹陷风城组页岩在不同沉积环境下黏土矿物的组合特征及动态转化规律进行研究。结果表明：在碱湖沉积中心，发育少量以蒙脱石及伊/蒙混层组合特征为主的黏土矿物（<5%），同时，大量碎屑黏土矿物（蒙脱石等）在强碱性的成岩环境下发生溶蚀，转化为钾长石等自生硅酸盐矿物，且由于CO32-/HCO3-存在导致沉积中心出现黏土矿物转化迟滞现象。边缘斜坡区的黏土矿物含量比沉积中心高（平均为11.57%），以伊利石、绿泥石、伊/蒙混层发育为主，其成岩环境经历了强碱性向弱碱—弱酸性的转变，原始碎屑黏土矿物在该种成岩环境下未发生溶蚀转化，随着地层温压的升高发生伊利石化和绿泥石化。黏土矿物在转化过程中会生成大量的自生石英等脆性矿物，同时会产生次生孔缝，对后续页岩油气的压裂开发具有积极影响。

有机质丰度是页岩油富集的重要物质基础,是页岩油甜点预测和资源评价的关键指标.与海相沉积相比,陆相湖盆页岩层系有机质丰度变化大,非均质性强,其形成和保存受水体盐度影响更明显.因此,揭示水体性质及其影响因素是揭示陆相有机质差异富集的关键科学问题.鉴于此,本文通过对比典型淡水(鄂尔多斯盆地长7段)与咸化碱湖(准噶尔盆地玛湖凹陷风城组)沉积与地球化学特征,揭示了淡水与咸化湖盆水体盐度具有动态变化的特征,淡水湖盆在有机质富集层段具有水体逐渐变咸的趋势,而咸化湖盆也具有水体变淡的特点.全球尺度上古气候的冷暖影响淡水与咸化湖盆的古生产力条件,是陆相湖盆富有机质沉积的主控因素;同时,陆相湖盆有机质多形成于缺氧含铁的水体环境,淡水湖盆咸化层段比咸化碱湖有机质保存效果更好.淡水湖盆长7段有机质水体分层不明显,火山活动等关键地质事件携带的硫酸盐会引起水体盐度发生快速变化,引起湖盆底部水体由长期铁化向硫化快速转变,利于有机质的保存;咸化碱湖玛湖凹陷风城组水体分层显著,火山或热液活动会导致底部水体盐度频繁硫化至甲烷厌氧氧化阶段,对有机质可能具有消耗作用.本研究可加深对陆相页岩油富集规律的认识,对指导页岩油勘探具有一定的理论意义.

Currently， significant hurdles lie ahead in China’s lacustrine shale oil exploration and exploitation， particularly due to the high clay mineral content， which severely impacts pore development in organic-rich shales. In this study， we take the medium- to high-maturity shale of the Qingshankou Formation (K2qn) in the Gulong Sag， Songliao Basin， China， as an example and analyze the dynamic evolution of the clay minerals and their effects on pore development by core observations， scanning electron microscopy， X-ray diffraction， physical property and nitrogen adsorptions to provide a valuable reference for the effective evaluation of lacustrine clay-rich shale oil reservoirs. Our findings reveal that the dynamic transformation of clay minerals in the Qingshankou Formation is classified into three stages based on diagenesis， thermal maturity， and mineral characteristics: the initial stage (vitrinite reflectivity (Ro) 1.3%). Clay minerals play crucial roles in controlling shale reservoirs during the rapid transformation process， which is evidenced by the formation of shrinkage fractures， enhanced pore connectivity， increased porosity， and expanded space for shale oil adsorption and storage. In addition， authigenic quartz can form during the transformation of clay minerals， contributing to increased reservoir brittleness and improving the potential for reservoir fracturing.

Due to the depletion of conventional hydrocarbon resources,both China and Russia are giving more attention to the exploration and production of unconventional oil and gas resources,especially those generated and accumulated within source *** an attempt to further understand the mechanisms of these resources,detailed mineralogical,lithological,and geochemical studies were performed to compare source rock samples from i)the Longmaxi Formation of the Lower Silurian in the Sichuan Basin(China),and ii)the Semiluksk Formation of the Frasnian Stage of the Upper Devonian in the Volga-Ural region of the East European Platform(Russia).The results showed that the main mineral of the source rocks of both formations is chalcedony that formed during an outpouring of deep fluids onto the sea *** thermal analyses of this mineral indicated similar thermophysical properties to those of the hydrothermal-sedimentary chalcedony from ***,a direct relationship between the chalcedony content and the total organic matter content in the samples from the two formations was *** presence of biophilic chemical elements in the siliceous component of the source rock samples indicate that high total organic content values were likely due to the presence of biophilic chemical elements in deep fluids,which led to the large-scale development of biota and subsequent accumulation of organic matter during *** findings also revealed that the organic matter in the source rocks of the two regions was at different stages of *** organic matter in samples from the Volga-Ural region was less mature and only at the early stage of oil generation,whereas the organic matter in samples from the Sichuan Basin reached both oil and gas generation *** Longmaxi Formation is already in the shale gas exploration and development stage,and the Semiluksk Formation could also be regarded as an exploration target for shale oil reservoirs.

Two-dimensional（2D） direct numerical simulations on the dynamics of three identical ferrofluid droplets suspended in a non-magnetic ambient fluid under a rotating uniform magnetic field are conducted, and the motion and deformation of the three ferrofluid droplets are studied in this paper. Results show that there are four modes(i.e., the three droplets' direct coalescence（TC）, the coalescence of two droplets and the subsequent planetary motion with the third droplet（CAP）, the three droplets' planetary motion（TP）, and the independent spin（IS）) for the three ferrofluid droplets, dependent on the magnetic Bond number（Bom） and the initial distance（d0） between two of the droplets. It is found that the decrease in d0and the increase in Bomcan make the droplets' mode change from the IS to the planetary motion, and then turn to the ***, reducing Bomor d0is helpful for the droplets to become merged.
