油气运聚是源外层系规模性成藏的关键之一。利用渤海湾盆地渤中地区丰富的三维地震和钻井数据分析,从断裂带深层垂向输导、馆陶组二次汇聚及明化镇组下段(明下段)侧向分流3个主要运聚环节分析入手,对明下段砂体烃柱高度进行分析。研究认为,烃源超压-断层活动耦合作用是断裂带垂向输导的关键,在烃源充足条件下断裂带分形维数大于0.7时,油气垂向输导能力较强;富砂型层系形成的早期油藏控制油气二次汇聚能力,利用馆陶组圈闭面积和有效幅度等计算汇聚系数,当馆陶组汇聚系数大于700 km3时,对应明下段具备发育大、中型油田的基础;断层的泄压控制浅层砂体侧向分流环节,利用砂体高部位和低部位断-砂接触面积计算泄压系数,当明下段砂体泄压系数大于2.0时,砂体烃柱高度可超过30 m。3个主要运聚环节紧密配合,是富生烃凹陷源外层系高丰度油藏形成的必要条件。

Calcium carbonate crystallization was performed in hydrogel of hydroxypropylmethyl cellulose (HPMC). Results showed that the polyhydroxy functionalities in HPMC gel network facilitated the nucleation of aragonite which was not found in experiment without HPMC hydrogel and in experiment using methylcellulose (MC) hydrogel as template. On the other hand, due to the unique assembly of the macromolecules in HPMC hydrogel network, which was different from other hydrogels used in some previous reports, particular crystal morphology, corncob-like CaCO_3, was obtained for the first time.

断裂体系发育是珠江口盆地文昌A凹陷西部地区新生代构造演化的重要表现形式。利用最新的三维地震资料,在精细刻画断裂体系静态特征的基础上,结合断层活动速率计算恢复断裂体系的动态演化过程,明确了文昌A凹陷西部地区新生代断裂体系发育的时空差异;并结合区域应力背景分析,探讨了断裂体系演化的成因机制,认为新生代以来三大板块间俯冲、碰撞及古南海俯冲消亡、新南海扩张共同造成的南海北缘区域伸展应力场顺时针旋转控制了断裂体系演化的时空差异。研究表明,文昌A凹陷西部地区断裂体系的发育演化经历了裂陷、拗陷与构造活化三个阶段,分别发育了NE(NEE)向、近EW向以及NW(NWW)向三组优势方向断裂,揭示了区域应力场伸展方向由NW—SE向到近SN向再到NNE—SSW向顺时针转变的过程;依据断裂的组合及沿承关系可将其划分为早期发育的NE向与后期发育的NW向两组交叠断裂带,NE向断裂带活动强度大、具有强烈伸展性质,NW向断裂带与基底先存断裂密切相关,活动强度弱、叠加一定走滑性质。文昌A凹陷西部新生代断裂体系演化的时空差异是对南海北缘区域应力场顺时针旋转的响应。

Here we presented a novel technology to achieve a Super-hydrophobic coating with microscopic roughness on copper surface. First, make a layer of verdigris grow on the fresh pure copper surface. Gain it by exposing the copper to air and the mist of acetic acid solution. The green coating is a mixture of basic copper（II） carbonate and copper（II） acetate. Second heat the coating and make it decompose to CuO. Lastly, form an n-octadecanethiol self-assembled monolayers coating on the outermost surface. Contact angle test, scanning electron microscope analysis and electrochemical testing were carded out to characterize the surface, and a heat transfer experiment for dropwise condensation of steam was performed also. Results show that the modified surface bears a few Super-hydrophobic features, the static contact angle is higher than that in literatures, reaching 153.1±1.7°. The microscopic roughness can be seen in SEM images, differing much from H2O2 etched surface and bare copper surface. The condensation of steam on the surface is a typical form of dropwise condensation, in the measured range of temperature difference, under 0.1 MPa, the average convection heat transfer coefficients of the vertical surface are 1.7-2.1 times for those of film condensation. At the same time, the inhibition efficiency of surface is improved to some extent comparing with the same kind of SAMs, which suggests that the lifetime of maintenance dropwise condensation would have the possibility to surpass the existing record.

为明确含油气盆地中断裂体系结构特征与油气藏分布的关系,文章以珠江口盆地珠三坳陷文昌A凹陷西部地区为研究对象,在对各层系断裂精细解析的基础上,通过对断裂网络体系的节点、分支类型分析及分维值计算,定量表征了研究区断裂网络体系的拓扑结构及分形特征,并就断裂网络体系拓扑结构、分形特征与油气藏分布的关系进行了探讨。研究结果表明:受控于区域拉张应力顺时针方向的转变,研究区断裂发育以NE向为主转变为以NWW向为主;不同层系断裂体系的拓扑结构具有差异性,珠三南断裂、珠三6号断裂和珠三2号断裂附近拓扑值较高,由深至浅断裂体系的I节点的比例逐渐增大,Y、X节点的比例逐渐减小,I-I分支的比例逐渐增大,I-C、C-C分支的比例逐渐减小,连通性由好变差;不同层系断裂体系的分形特征具有时空差异,NE向断裂带和NW向断裂带交汇区分维值较高,由深至浅断裂体系的分维值先增大后减小,复杂程度先增强后减弱;断裂体系的拓扑结构、分形特征与与油气藏分布具有良好的耦合关系,高拓扑值与高分维值的叠合区是油气成藏的有利区。

植被恢复可促进重构土壤发育,调控生物地球化学循环和发挥生态系统功能。因此深入研究露天矿区植物恢复下土壤丰富和稀有微生物类群变化对改善矿区生态环境至关重要。采集内蒙古准格尔旗黑岱沟露天矿东排土场裸地(CK)、苜蓿(GL)、沙棘(BL)、油松(CF)、杨树(BF)和杨树+油松(MF)6种复垦样地土壤,利用高通量测序、共现网络和相关性分析等探测植被类型对土壤丰富、稀有细菌和真菌群落结构组成和多样性的影响机制。结果表明:①不同植被恢复类型对土壤理化性质和酶活性影响存在显著性差异(P<0.05),有机质(SOM)、铵态氮(AN)和亮氨酸氨基肽酶(LAP)酶活性等均显著高于CK。BL对土壤SOM、硝态氮(NN)和有效磷(AP)积累有优势,显著提高了脲酶(URE)、LAP和碱性磷酸酶(ALP)酶活性(P<0.05)。②植被类型显著影响了土壤丰富和稀有微生物群落结构组成(P<0.05),丰富和稀有细菌种类多于真菌,但真菌丰度变化更为显著,尤其是稀有真菌。不同植被恢复类型的丰富和稀有细菌,及稀有真菌群落Shannon指数高于CK,且与CK的群落结构间存在显著差异(P<0.05)。③不同植被恢复类型均提高了丰富和稀有细菌、真菌的网络拓扑参数和复杂度。移除节点改变自然连通性的幅度测试结果表明BL增强了土壤丰富细菌、丰富和稀有真菌网络的稳定性和对外界干扰的抵抗力。④土壤URE、SOM和ALP是土壤微生物群落结构变化的主导因子。BL处理组中pH、SOM、AP、BG(β-葡萄糖苷酶)、URE和ALP均显著影响丰富和稀有微生物群落(P<0.05)。综上认为,BL恢复模式对矿区复垦土壤质量改善效果更好,研究结果可为植被修复受损矿山复垦土壤及微生物资源的开发利用提供理论依据。
