The theories involved in gravity flow deposits have become a hot and difficult topic of international sedimentology research. Compared with submarine fan reservoirs, the study on the single sandbody architecture of sublacustrine fan reservoirs is relatively weak, especially the study on quantitative architecture models is still rarely reported. Based on the integrated analysis of the core, well logging and production data, the architectural characteristics of Triassic Chang-6 oil-bearing interval in Heshui area of Ordos Basin were investigated, and the distribution of the single sandbody of sublacustrine fan in depression lacustrine basin was determined. The results show that 6 architecture elements are identified in sublacustrine fan, including main channel, branch channel, lobe, lobe edge, inter-channel and inter-lobe. Based on the single sandbody boundary recognition mark of exploration wells and horizontal wells, the boundary of single sandbody was divided. The lobe complex is composed by multiple individual lobes as the compensational superimposition pattern, which is related to the short-term base-level changing. The single lobe is tongue-shaped on the plane and narrower in the proximal region while wider in the distal region. There is an obvious linear positive correlation between maximum width and maximum thickness, with the aspect ratio ranging from 100 to 160. Finally, according to the analysis results of the architecture in the study area, the three-dimensional architecture model of sublacustrine fan in the depression lacustrine basin is established. The research results have important guiding significance for the adjustment of the oilfield development program and the exploitation of remaining oil. [ABSTRACT FROM AUTHOR]

【Objective】 The study aimed to estimate the harvest loss rate of sweet potato, explore its influencing factors and offer proposes on reducing the loss. 【Method】 This paper measured the loss of sweet potato harvest in Sichuan and Henan, China, using a combination of field survey, questionnaire survey and empirical research. 237 rural households from the Rural Fixed Observation Point of the Ministry of Agriculture were included in the questionnaire survey.【Result】 The loss rate of manual harvest was 2.28 %, the loss rate of mechanical harvest was 4.94 %, and the comprehensive loss rate was 2.97 %, while the manual harvest loss rate estimated by farmers was 4.7 %. At the same time, the results showed that sweet potato varieties, harvesting models, harvesting methods, harvesting time, soil type, farmers’ age, education level, total annual household income, pest level, whether planting in the next season after harvest and whether intercropping, had a great effect on sweet potato harvest losses. 【Conclusion】 Therefore, this paper suggests that farmers should adjust the depth of operation according to different varieties and topography and choose the appropriate type of machine. Besides, the government should promote the knowledge of reducing the loss of sweet potato harvest to farmers. [ABSTRACT FROM AUTHOR]
