准噶尔盆地南缘台13井区侏罗系油藏表征与建模

Junggar Basin has a large amount of recoverable reserves, However, due to the unfavorable factors, such as bad seismic data quality, complex structure with many faults and less wells, the exploration of oil and gas is still relatively limited, so advanced theoretical guidance and effective technical supports are desirable. Based on the theories of sedimentology, as well as comprehensive studies of outcrops, seismic data, drilling data and setting of this area, the paper establishes the isochronous correlation framework, and analyzes the sedimentary facies types and provenance direction, and obtains the profile and plain maps of the sedimentary facies combined with the logging constrained inversion. Then the paper analyzes the reservoir controlling factors, reservoir lithology attribute, 4-property relationship and sensibility based on the sedimentary facies research, and sets up a 3D geological model using facies controlled modeling. Finally, the paper optimizes some target areas with the conclusions of reservoir, structure and reservoir formation.Firstly, the paper establishs the isochronous correlation framework by the seismic data, drilling data and setting of this area. The sedimentary facies in Tai13 well block are braided river and meandering river according to the analysis of the lithology attribute, logging facies and sedimentary structure attribute of outcrop. The concept of “wetland” is put forward for the first time. The provenance direction of Badaowan and Qigu formation is obtained by the geology setting, sedimentary setting and paleocurrent direction. The paper obtains the profile and plain maps of the sedimentary facies from the sand value of the wells and the sand thickness maps from the logging constrained inversion. Then, this paper takes characteristics and control factors of the Jurassic reservoirs analysis on thin section observation, scanning transmission electron microscope observation and find out the petrology characteristics of reservoir, space types of reservoir and lithofacies division. In this area, primary pores dominate in the reservoir pores, which believed that sedimentation played the most important roles of the reservoir quality and diagenesis is the minor factor influencing secondary porosity. Using stochastic modeling technique，the paper builds quantitative 3-D reservoir Parameter. Finally, combined the study of structure and reservoir formation, the reservoir distribution regularity is concluded: (a) structures control the reservoir formation and accumulation. (b) Locating in the favorable sedimentary facies belt. And the area which meets these conditions mentioned above is a good destination for exploration.

淡水湖泊水体中溶解有机氮测定方法的对比

溶解有机氮（Dissolved Organic Nitrogen，DON）是天然水体中氮的重要组成部分，目前研究相对很少．本文对淡水中测定DON的两种常见方法即过硫酸钾湿氧化法（Persulfate Oxidation，PO）和高温催化氧化法（High Temperature Cataytic Oxidation，HTCO）进行了对比研究．结果表明：两种方法各有特点，湿氧化法相对较为理想．湿氧化法对不同氮标准化合物的回收率较高，平均为96．0±3．O％以上（杂环氮化合物除外）；对湖泊淡水样品，用PO法测定溶解有机氮的相对标准偏差范围为6．2％-12．5％．高温催化氧化法对不同氮标准化合物的回收率较低，平均为68．4±13．6％，需作进一步条件优化.
