Based on the latest drilling cores,thin sections,and 3D seismic data,types,features,and evolution processes of Cambrian-Ordovician carbonate platforms in the Gucheng and Xiaotang areas are studied,and favorable exploration zones in this area are also *** are two types of carbonate platforms developed in the Cambrian-Ordovician in the Gucheng-Xiaotang area,namely,carbonate ramp and rimmed platforms,and the evolution process of the platform in the Gucheng area is different from that in Xiaotang *** the Early Cambrian,the study area was a homoclinal carbonate *** the Middle to Late Cambrian,it evolved into a rimmed platform,with 5 phases of mound shoals *** the southern area,mound shoals were in progradational arrangement and the third and fourth stages of mound shoals suffering exposure and further developed abundant karst *** the northern area,the mound shoals appeared in a superposition of aggradation-weak progradation,the third,fourth,and fifth stages of mound shoals suffered exposure and dissolution,and the platform slope developed gravity flow *** the Early to Middle Ordovician,the southern area gradually evolved into a distally steepened carbonate ramp,where retrogradational dolomitic shoal developed;while the northern part experienced an evolution process from a weakly rimmed platform to a distally steepened carbonate ramp,and developed two or three stages of retrogradational mound *** high-frequency oscillation of sea level and local exposure and dissolution were beneficial to the formation of mound or shoal reservoirs in platform margin and ramp,and the configuration of these reservoirs with low energy slope-basin facies source rocks could form good oil-gas enrichment *** dolomitic shoal in the Ordovician platform ramp is the practical exploration field for increasing reserve and production in the Gucheng *** mound shoal at the Cambrian rimmed platform margin is the key exploration object in the X

Based on the latest drilling core, thin section, 3D seismic, well logging data as well as exploration results, the sequence stratigraphy and sedimentary microfacies of the Middle-Lower Ordovician carbonates in Gucheng area, and their controlling effects on the development of reservoir were examined by the theories and methods of fine carbonate *** results show that the Middle-Lower Ordovician in Gucheng area is a set of typical carbonate ramp deposits, which can be divided into 10 microfacies in 4 subfacies as follows: back ramp, inner shallow ramp, outer shallow ramp, and deep ramp. The back ramp subfacies consists of muddy-dolomitic flat and dolomitic lagoon microfacies;it is dominated by lamellar micrite dolomite tight in lithology. The inner shallow ramp subfacies includes dolomitic shoal and dolomitic flat in shoal top and dolomitic flat between shoals microfacies;it is mainly composed of crystal dolomite with metasomatic residual structure, as well as abundant karst vugs and intercrystalline pores. The crystal dolomite has an average porosity of 4.36%. The outer ramp subfacies includes medium-high and low energy grain shoal and inter-shoal microfacies;it is dominated by sandy limestone,oolitic limestone, and micrite limestone with few pores. The deep ramp subfacies is dominated by low-energy argillaceous deposits, with local presences of storm shoal microfacies. The Lower-Middle Ordovician has six third-order sequences from bottom to top, among which sequence(SQ3) represents the third member of Yingying Formation. The main reservoir has three fourth-order high-frequency sequences. Apparently, the favorable reservoir in the study area is jointly controlled by sedimentary microfacies and high frequency sequence in the carbonate ramp. The former controls the primary pore structure, and the latter controls the intensities of karstification exposure and dolomitization in the penecontemporaneous period. The dolomitic shoals and top dolomitic flats of d

The programmable CRISPR-Cas genome editing technology,adopted from prokaryotic adaptive immune systems,has revolutionized genome engineering in plants(liu et al.,2022a).Many efforts have been made to improve the activity,specificity,and protospacer adjacent motif(PAM)variants of Class 2 Cas nucleases,such as Cas9,Cas12a,and Cas12b(liu et al.,2022a).However,their large size(∼1000–1400 amino acids)poses a challenge in scenarios requiring a compact Cas nuclease,particularly in urgent situations like plant virus-induced genome editing(Cheuk and Houde,2018;Li et al.,2021;Varanda et al.,2021).

基于最新钻井岩心、薄片和三维地震等资料,对塔里木盆地古城—肖塘地区寒武系—奥陶系碳酸盐台地类型、发育特征与演化过程进行研究,并探讨油气勘探的有利相带。研究结果表明,寒武纪—奥陶纪研究区发育碳酸盐缓坡和镶边台地两类台地,古城地区和肖塘地区台地演化过程存在明显差异。早寒武世研究区为一均斜缓坡,中—晚寒武世逐渐演变为镶边台地,发育5期台缘丘滩,南部古城地区丘滩呈进积型排列,第③、④期丘滩遭受暴露,溶蚀孔洞发育,北部丘滩呈加积—弱进积叠置,第③、④、⑤期丘滩发生抬升暴露溶蚀,台缘斜坡重力流沉积发育。早—中奥陶世南部演变为远端变陡的缓坡,发育退积型云化滩;北部肖塘地区经历弱镶边台地—远端变陡的缓坡演化过程,发育2~3期退积型台缘丘滩及颗粒滩。海平面升降和局部暴露溶蚀促使台缘丘滩及台内云化滩相优质储集层发育,加之其与低能斜坡—盆地相烃源灶的有效配置,形成良好的油气富集区带;奥陶系缓坡台地云化滩是古城地区增储上产现实领域,寒武系镶边台缘丘滩是肖塘地区勘探重点领域,寒武系斜坡重力流沉积可作为研究区潜在风险勘探领域。

为评估交通管控策略的环境效益,提出有效融合微观交通仿真模型和微观车辆排放模型的方法。利用VISSIM平台构建案例微观交通仿真模型,提出基于轨迹数据的不同速度区间的加减速特征,应用K-means聚类方法划分4种驾驶行为,通过驾驶特性标定仿真模型全局参数,描述了参数总敏感度以及参数之间相互作用的敏感度。利用DBSCAN(density-based spatial clustering of applications with noise)聚类分析并标定局部参数值,优化了参数标定流程。计算仿真轨迹工况,本地化MOVES(motor vehicle emission simulator)微观排放模型,得到交叉口不同流向和不同驾驶行为下的HC、CO、NO_(x)、CO_(2)排放。研究表明:仿真模型优化效果显著,所提方法可精确识别高排放的空间位置,解析排放与驾驶行为之间的联系。应用DBSCAN聚类分析参数寻优值有助于实现自动化标定流程,全局参数标定将速度分布χ^(2)误差由0.6327降至0.1306,加速度分布χ^(2)误差由0.1441降至0.0528,对于环境视角下仿真模型构建至关重要。

食品微生物污染导致的食品安全和腐败问题是食品工业的难题。如何在不改变食品质量及口感的情况下延长食品保质期是食品加工技术的研究重点。目前报道的一些抗菌物质,如纳米金属粒子、抗菌肽和植物提取物等,具有良好的抗菌活性,在较低浓度下就可杀死大量的致病菌,若采用合适的方法将其制备成食品包装材料则会增加其应用范围。静电纺丝技术反应条件温和,包封效率高,可以更好地保持抗菌物质的抗菌活性等优点,使其在食品工业的应用研究日益增多。本文介绍静电纺丝技术的原理以及纺丝条件对纳米纤维形态的影响,阐述不同抗菌纤维膜的制备方式、抗菌效果和机制以及应用现状,为静电纺丝抗菌材料的工业化制备和应用提供参考。

基于最新钻井岩心、薄片、三维地震和测井资料以及近年勘探实践,采用精细碳酸盐岩沉积学理论方法对塔里木盆地古城地区中—下奥陶统碳酸盐岩层序地层和沉积微相进行深入研究,并探讨二者对有利储集层发育的制约作用。结果表明,古城地区中—下奥陶统为1套典型的碳酸盐缓坡相沉积,进一步可细分为内缓坡、浅缓坡内带、浅缓坡外带、深缓坡共4种亚相及10种微相。内缓坡亚相由泥云坪和白云质潟湖微相组成,岩性以纹层状泥粉晶白云岩为主,岩性致密;浅缓坡内带亚相发育云化滩、滩顶云坪和滩间云坪微相,主要由具交代残余结构的晶粒白云岩组成,晶间孔及溶蚀孔发育,平均孔隙度达4.36%;浅缓坡外带由中—高能滩、低能滩和滩间海微相组成,岩性为砂屑、鲕粒灰岩和薄层泥晶灰岩等,孔隙欠发育;深缓坡以低能静水泥沉积为主,局部发育风暴滩沉积。中—下奥陶统自下而上依次发育6个三级层序,其中主力储集层SQ3层序鹰山组三段发育3个四级高频层序。研究区有利储集层发育明显受碳酸盐缓坡沉积微相和高频层序双重控制,前者控制原生孔隙结构,后者控制准同生期白云石化作用和暴露溶蚀强度。不同时期浅缓坡内带云化滩及滩顶云坪纵向叠置、横向拼接,可构成一定规模的似“台缘带”优质储集层,是碳酸盐缓坡相有利勘探相带。
