项目标书摘要：本年度是项目立项研究的第二年。重点完成塔里木、四川和华北三大陆块中新元古界—寒武系地质资料、地质样品的采集整理，开展储层样品常规和微观分析，建立多维多尺度储层非均质性表征与评价技术，明确超深层白云岩储层孔隙分布特征；研究了华北中元古界、四川盆地新元古界和塔里木新元古界—寒武系微生物碳酸盐岩发育过程，主要取得了如下进展:1、提出华北中元古代微生物岩有三个发育阶段;2、首次明确了奇格布拉克组的微生物礁建造、沉积特征及展布范围，建立成岩作用序列，明确了孔隙类型及物性特征;3、初步划分了碳酸盐岩(微生物岩为主)微孔隙的主要类型，微孔隙大小分布及连通性等特征；并以蒸发瀉湖—潮坪相碳酸盐岩(微生物岩为主)为例，详细研究了微相、结构特征、孔隙类型及物性参数关系，提出了米级旋回下储集体发育特征。本年度发表/接收论文8篇,SCI/EI收录8篇，课题编号第一标注6篇，第二标注2篇。整体来看，本年度，课题在基础研究、图件编制、知识产权和人才培养等方面均取得突出成就，获显著社会和经济效益，有力支撑了项目进展和目标任务的实施。

Application Abstract: This is the second year of our project research.We focus on the compilation of the Neoproterozoic-Cambrian geological data and geological samples in the Tarim,Sichuan and North China continental blocks,and carry out routine and microscopic analysis of reservoir samples to establish multi-dimensional and multi-scale reservoir heterogeneity characterization and evaluation.The technology is used to define the pore distribution characteristics of ultra-deep dolomite reservoirs.The development process of the Mesozoic Paleozoic in North China,the Neoproterozoic in the Sichuan Basin and the Neoproterozoic-Cambrian microbial carbonate rocks in the Tarim Basin has been studied.The main progress has been made as follows:1.It is proposed that the Mesozoic microbial rocks in North China have three developmental stages;2.The microbial reef construction,sedimentary characteristics and distribution range of the Chigbrak Formation are identified for the first time,and diagenesis sequences are established,and pores are defined.Type and physical characteristics;3.Preliminary classification of the main types of micropores of carbonate rocks(mainly microbial rocks),micropore size distribution and connectivity;and evaporation of lagoon-tidal flat carbonates(microorganisms)Taking rock as the main example,the relationship between microfacies,structural features,pore types and physical parameters was studied in detail,and the development characteristics of reservoirs under the rice-level cycles were proposed..This year,8 papers were published or accepted,8 of them were SCI/EI paper.The subject number was firstly marked in 6 papers and secondly marked in 2 papers.In summary,this year,we made outstanding achievements in basic research,map compilation,intellectual property and personnel training,and achieved significant social and economic benefits,which strongly supported the progress of the project and the implementation of the target tasks.
