| 1 | Sequence sedimentary evolution and reservoir distribution in the third and fourth members of Sinian Dengying Formation,Gaomo area,Sichuan Basin,SW China显示文摘Based on comprehensive analysis of cores,thin sections,logging and seismic data,the sequence stratigraphy and sedimentary evolution of the third and fourth members of Sinian Dengying Formation(Deng 3 and Deng 4 members for short)in the Gaomo area of Sichuan Basin were investigated,and the favorable zones for reservoir development in the Deng 3 Member and Deng 4 Member were predicted.(1)Two Type I and one Type II sequence boundaries are identified in the Deng 3 and Deng 4 members.Based on the identified sequence boundaries,the Deng 3 and Deng 4 members can be divided into two third order sequences SQ3 and SQ4,which are well-developed,isochronal and traceable in this area;the SQ3 thins from west to the east,and the SQ4 thins from northwest to southeast.(2)The sedimentary environment from the depositional period of SQ3 to SQ4 has experienced the evolution from mixed platform to rimmed platform,and the platform rimmed system on the west side is characterized by the development of platform margin microbial mound and grain shoal assemblages.The intraplatform area is a restricted platform facies composed of a variety of dolomites,and there are local micro-geomorphic highlands of different scales and scattered intraplatform mounds and shoals.(3)The Deng 4 Member reservoirs,with obvious facies-controlled characteristic,are mainly distributed in the upper part of high-frequency upward shallow cycle and the high-stand systems tract of the third-order sequence vertically,and are more developed in the platform margin belt than in the intraplatform belt,and more developed in the Gaoshiti platform margin belt than in the west Suining platform margin belt on the plane.(4)Three types of favorable reservoir zones of Deng 4 Member have been finely delineated with 3D seismic data;among them,the mound and shoal facies zones developed in the ancient highlands of the intraplatform are the first choice for the next exploration and development of the Deng 4 Member. | TAN Lei LIU Hong CHEN Kang NI Hualing ZHOU Gang ZHANG Xuan YAN Wei ZHONG Yuan LYU Wenzheng TAN Xiucheng ZHANG Kun | 2022 | Petroleum Exploration and Development2022，49，5： | 1 |
| 2 | Effect of Straw Mulching on Vineyard Ecology and Fruit Quality of Southern Jiangsu Province显示文摘[Objectives] The ecological environment of orchard has a direct impact on fruit quality,and straw mulching can effectively improve the physicochemical indicators of orchard soil,so as to achieve environmental protection and yield increase.[Methods]Tests were carried out for 3 consecutive years of mulching straw in vineyard of southern Jiangsu Province.[Results]The results showed that mulching straw continuously could effectively improve soil physicochemical properties,weed controlling effect,and the photosynthetic rate of leaves,as well as the yield and quality of grapes.The contents of total nitrogen,available phosphorus,quickacting potassium and organic matter increased up to 91.67%,259.76%,442.39% and 34.30%,respectively.Soil bulk density decreased by 7.15%,and the weed plant control effect reached 87.45%.The increased of fresh weight was up to 93.55%,and the increase of the leaf parenthetical rate was up to 18.24%.The increases of soluble solids content and single grain weight reached up to 8.82% and 12.75%.The rate of dehiscent fruit was decreased by 50.89%.The grape could pick for sale 3 days ahead,and the increase of unit area yield reached up to 13.16%.[Conclusions]Straw mulching cultivation in vineyard is a good model for efficient recycling of crop straw and safe production of quality grape,and it provides a new technical approach for straw utilization,promising with good economic and ecological benefits. | Youmei WANG Jinfang HE Wenzheng ZHANG Honghai ZHANG Junyi FU Zhizhong LYU Qin DONG | 2018 | Agricultural Biotechnology2018，7，6： | 0 |
