Dual atomic catalysts （DAC）,particularly copper （Cu2）-based nitrogen （N） doped graphene,show great potential to effectively convert CO2and nitrate （NO3-） into important industrial chemicals such as ethylene,glycol,acetamide,and urea through an efficient catalytical process that involves C–C and C–N ***,the origin of the coupling activity remained unclear,which substantially hinders the rational design of Cu-based catalysts for the N-integrated CO2reduction reaction （CO2RR）.To address this challenge,this work performed advanced density functional theory calculations incorporating explicit solvation based on a Cu2-based N-doped carbon (Cu2N6C10) catalyst for *** calculations are aimed to gain insight into the reaction mechanisms for the synthesis of ethylene,acetamide,and urea via coupling in the interfacial reaction *** to the sluggishness of CO2,the formation of a solvation electric layer by anions （F-,Cl-,Br-,and I-） and cations (Na+,Mg2+,K+,and Ca2+) leads to electron transfer towards the Cu *** process significantly accelerates the reduction of *** results reveal that*CO intermediates play a pivotal role in N-integrated ***,the Cu2-based N-doped carbon catalyst examined in this study has demonstrated the most potential for C–N coupling to *** findings reveal that through the process of a condensation reaction between*CO and NH2OH for urea synthesis,*NO3-is reduced to*NH3,and*CO2to*CCO at dual Cu atom *** dual-site reduction facilitates the synthesis of acetamide through a nucleophilic reaction between NH3and the ketene ***,we found that the I-and Mg2+ions,influenced by pH,were highly effective for acetamide and ammonia synthesis,except when F-and Ca2+were ***,the mechanisms of C–N bond formation were investigated via ab-initio molecular dynamics simulations,and we found that adjusting the micro-environment can change the dominant side reaction,shift

岩溶储层在碳酸盐岩储层中占有重要的地位,但过去一直认为表生期碳酸盐岩地层抬升至地表受大气水潜水面控制的岩溶作用是其主要成因。本文在充分认识塔北英买2地区构造地质背景的基础上,通过岩石学、地球化学及其与岩溶成因和控制因素关系的综合分析,提出在地层沉积序列完整的内幕区也可形成大气水岩溶作用改造的缝洞型储层。以岩芯和薄片观察为基础,进行不同组构方解石的碳氧同位素、锶同位素、稀土元素、电子探针、阴极发光和包裹体等地球化学分析,综合岩石学与地球化学特征,分析了岩溶流体性质和来源,认识到大气水是主要的岩溶流体,对储层形成起决定性作用;深层热液在后期起到了改造作用。通过对英买2高陡构造和走滑断裂发育特征与演化分析,认识到构造形成和断裂的发育为岩溶作用提供了必要条件。进而,建立了一种受高陡构造和断裂控制的新型大气水岩溶作用模式,即碳酸盐岩地层虽上覆厚层碎屑岩地层,但在后期抬升形成隆起,并伴生走滑断裂发育的背景下,大量裂缝发育于隆起顶部的碳酸盐岩地层上部,大气水可沿断裂下渗并在裂缝带发生岩溶作用,从而形成大型缝洞型储层。该模式突破了暴露型潜山岩溶模式的局限,深化了地层沉积序列完整的碳酸盐岩内幕区岩溶储层成因机理的认识,扩宽了岩溶储层油气藏勘探的思路。

塔里木盆地塔中地区奥陶系碳酸盐岩油气探明储量近1.5×108t,而且仍有巨大的勘探潜力,储层属性一直被认为是礁相储层。通过76口探井的岩心观察,完井地质报告、试油成果的分析,铸体薄片的鉴定,尤其是对有工业产能的20多口探井试油井段近500个铸体薄片的详细鉴定和复核,指出塔中地区奥陶系碳酸盐岩有效储层类型复杂多样,有泥亮晶棘屑灰岩、层间古岩溶和古潜山风化壳型储层,分别与沉积间断面、平行不整合面、角度不整合面相关。虽然发育了小规模的礁丘体,但不是有效储层,更不可能形成规模效益储量。储层属性的重新认识对塔中地区勘探潜力的重新评估和勘探理念的转变均具重要的指导意义。

微生物碳酸盐岩中有机质在同生-早成岩阶段的降解既可以产生酸性流体对碳酸盐颗粒进行溶解,扩大后期成储流体通道,有利于储层发育;但也可能导致孔隙水处在碱性环境下,形成碳酸盐矿物胶结,阻碍溶蚀流体对储层的改造.因此,同生-早成岩期有机质降解对微生物岩储层储集空间的形成有重要影响,但研究薄弱.以四川盆地北部地区上震旦统灯影组四段(灯四段)微生物碳酸盐岩为例,综合岩石学和原位微区地球化学分析(LA-ICP-MS),开展了这一降解过程的地球化学示踪研究.结果显示,当微生物碳酸盐岩中的有机质处于有氧降解时,微亮晶和亮晶组构均具有Ce负异常;当亮晶组构Ce元素转变为正异常时,表明有机质进入厌氧降解阶段.此外,微生物岩亮晶组构中Cr含量高于微亮晶组构,可以作为有机质降解经过了硝酸盐还原过程的识别标志.如果有机质被Fe-Mn氧化物氧化降解,则会造成微生物岩微亮晶组构中Fe含量高于亮晶组构.随着成岩环境的还原状态进一步加强,有机质降解进入硫酸盐还原阶段,将导致微生物岩中亮晶组构相对于微亮晶组构富集Cu,Mo元素.因此,Ce,Cr,Fe,Mo,Cu等元素在微生物岩不同岩石组构中的变化可以有效识别微生物岩同生-早成岩阶段有机质降解的成岩环境并示踪有机质降解过程.

下奥陶统白云岩是塔里木盆地最现实的重点勘探领域。文中在分析塔里木盆地早奥陶世构造、沉积及古气候等地质背景的基础上,以前人对白云岩的结构分类为基础,从白云岩发育产状出发,将塔里木盆地下奥陶统白云岩划分为灰岩中零散白云石、灰岩中斑状白云石、层状白云岩和沿断裂分布白云岩4类,白云石含量层位上自下而上具有总体减少的趋势。各类白云岩在岩石学特征和发育分布上具有较为明显的差异,局部可重叠出现。灰岩中零散白云石和斑状白云石的岩石学和地球化学及发育分布特征均反映其主要由浅埋藏白云石化作用形成;层状白云岩和沿断裂分布白云岩形成于中深埋藏白云石化作用;各类白云岩的产状特征差异受控于沉积期海平面变化、海水性质及埋藏条件等因素。沿断裂分布白云岩的形成和分布与断裂密切相关,是重要的储集岩石类型。白云岩储集层的形成主要是后期改造的结果,埋藏白云石化作用并未对大规模白云岩储集层的形成起到建设性作用,伴生或后期流体再运移导致的溶蚀作用为其主要成因。
