“…River migration patterns are of great significance in guiding the reconstruction of ancient channels. Migration patterns determined in this study are comparable to the results of other studies that have investigated using Google Earth maps and outcrops (Nami 1976;Ghinassi et al 2014;Lin et al 2018). These migration patterns include six planform migration models, which have been successfully used to reconstruct a modern fluvial system by (Shan 2017).…”

“…geomorphology, and other physical processes (Güneralp et al 2012). Previous studies have characterised meandering channel migration behaviour and shape (Brice 1974;Hickin 1974;Hooke 1984;Gutierrez and Abad 2014;Schwendel et al 2015;Lin et al 2017) and predicted meander evolution by analytical and numerical models (Johannesson and Parker 1989;Abad and Garcia 2006;Frascati and Lanzoni 2009;Kasvi 2015;Langendoen et al 2016). Field-based studies using terrestrial LiDAR for bank morphology can also help to interpret river bed and planform morphology (Abad et al 2013;Konsoer et al 2016).…”

Reconstructing meandering paleo-channels is attracting global research attention. We implemented a novel method by comprehensively integrating migration models and sedimentary structures. Firstly, the migration architectures of the corresponding characteristics in planform and cross-sectional models were summarised as expansion, translation, expansion and translation, expansion and downstream rotation, constriction and downstream rotation, and expansion and countercurrent rotation models. Secondly, full continuous core data from 270 dense drilling wells were collected from the Daqing Oil Field in the Songliao Basin, China, providing information on rock textures, sedimentary cycles, and boundary information for the two layers being studied. Through a comprehensive analysis of dense drill cores and logging data, the abandoned channels and the initial and final channel centrelines were identified. Consequently, four profiles, including one longitudinal and three transverse sections, were constructed to reveal the cross-sectional structures and planform migration architecture. Profile interpretation revealed the evolution from the initial channel centreline to the final centreline. Using a method of rational interpolation, we were able to reconstruct the migration architecture of the meandering channels. The results showed that the average ancient bankfull width (W c ) was approximately 100 m, a single meandering belt was 800 m, the radius of the curvature was 250 m, the length of the channel bend was 700 m, the average meander wavelength was 1300 m, the sinuosity was 3.0, and the annual average discharge rate was 450 m 3 /s. Furthermore, we compared the results from empirical equations, which verified that our reconstruction is both feasible and potentially widely applicable.

“…By characterizing and analyzing the rules of migration architecture of meandering rivers, it will be easier to guide and understand the distribution characteristics of underground sand bodies (Sui, 2006;Willis & Tang, 2010;Mithun, Dabojani, & Misbah, 2012;Lin, 2017). Although an increasing amount of literature focus on the ancient and modern fluvial system, the evolutional process analysis of geomorphology of meanders remains an issue (Willis & Tang, 2010;Ielpi & Ghinassi, 2014;Debnath, Pan, Ahmed, & Bhowmik, 2017;Lin, Shan, & Chen, 2017a). This paper crucially aims to focus on four targets, (1) A comprehensive scheme for characterizes the morphological elements of planform architecture of meandering rivers; (2) New method of characterization factors, including descriptive elements and dynamic parameters; (3) Geomorphology process and migration characteristics of different meandering channels; (4) a comprehensive set of model for channel migration structure of meandering rivers.…”

The meandering process has always been the topic through years and still remains a lot of unsolved mysteries. One of the most important focus is the migration architectures and models that the meandering channels follow. This article chooses the Nowitna River as the study object of the typical meandering river with high migratory processes. Though the high-resolution historical satellite images by the techniques of Google Earth and ACME Mapper, 50 meanders in the river is studied and 6 of which are chosen for meticulous characterization. During the process, the planform structure of meandering channel is re-examined and 29 kinds of architecture elements are systematically established. More importantly, in order to make a fine quantitative characterization of the channel structure of meandering river, 5 kinds of characterization parameters are proposed, extraordinarily, the parameters of the difference of along-current deflection angle, a difference of counter-current deflection angle, and expansion coefficient, these three are firstly brought forward and applied introduction. In addition, the conception of sinuosity index and curvature are also different from the original definition. Though these architectures elements the meandering process and migration structure of the Nowitna River is demonstrated. 6 kinds of planform migration structures is revealed with the quantitative characterization of characterization parameters and 9 species of meandering channel migration patterns are concluded and discussed.

“…The thin interlayer is comparatively non-infiltrative layers unstably distributed in sandstone, which can prevent or control fluid running. Through the practice of oilfield, the thin interlayer in the reservoir plays an important role in fluid seepage of each layer (Wang, Xu, & Zhong, 2010;Miall, 2014;Lin, 2017;Lin, Shan, & Chen, 2017a;Matapour & Karlsen, 2017).…”

This paper investigates the reservoir architecture of thin interlayer within meandering river monosandbody in the thick-bedded oil layers. The thin interlayer within the monosandbody of the terrestrial reservoir is one of the dominant factors which form the reservoir heterogeneity of fluid motion. It is of equal importance in comparison with the rhythmic distribution of permeability, and it is also the important content of the elaborate representation of reservoirs. However, previous researches of the heterogeneity of reservoir focus mostly on the theory of distribution disparity of the permeability and neglect the influence of thin interlayer on the heterogeneity. Therefore, taking the PⅠ2 individual reservoir at the Putaohua reservoir formation in Daqing oilfield as an example, this paper analyzes the distribution, formation, and the three-dimensional construction of the internal thin interlayer of the monosandbody from a new point of view, on the basis of which a set of cycle research technique about it is put forward. With the method of configuration parameter extraction, which is most important before establishing interlayer configuration in three dimensions, this study clarifies the classification, causes of formation and the differences of distinct monosandbodies. Ultimately, four categories of thin interlayer according to the characteristics of the studied area is divided and two dominate causes for thin interlayer formation is discussed: argillaceous and arenaceous rock interlayer through deposition and interlayer in process of sedimentary diagenesis.For the convenience of the study, here mainly focuses on the thick -thin interlayer. Techniques are taken the use of determining the obliquity of the thin interlayer superface based on the configuration of paired wells and abandoned channel surface. The causes for thin interlayer and their classification, distribution and the three-dimensional construction are entirely revealed, which would possess important geologic meaning for taking affective engineering measures in the aspects of the elaborate representation of oil reservoir, and the research of remaining oil formation and distribution.
