Sedimentary Microfacies and Sand Body Characteristics at Segment 2 of the Sangonghe Formation in Oilfield A on the South Slope District of the Mahu Depression

The South Slope District of the Mahu Depression in the Junggar Basin, a major favorable zone for middle and superficial oil–gas exploration, has experienced industrial gas flow. However, research on the sedimentary microfacies characteristics of Segment 2 of the Sangonghe Formation, the main oil-bearing formation, remains lacking. In this study, the rock type, sedimentary tectonics, and sedimentary microfacies of Segment 2 of the Jurassic Sangonghe Formation in the South Slope District of the Mahu Depression were thoroughly investigated through 3D seismic, rock core, and logging data. Moreover, the sedimentary modes and distribution characteristics of the sand bodies in the study area were further analyzed. Results showed that subfacies at the front edge of the braided river delta are developed at Segment 2 of the Sangonghe Formation, which can be further divided into four microfacies types, namely, underwater distributary channel, sheet sand, estuary dam, and interdistributary bay. The estuary dam is only developed at local positions in the work area. The vertical evolutionary laws from Segment 2 of the Sangonghe Formation to Segment 3 of the Sangonghe Formation are explicit and manifest as retrogradation from the subfacies at the front edge of the braided river delta to the prodelta. The sand bodies formed by frequent swings of the underwater distributary channels are the main reservoir bodies, and the lithology is mainly fine-grained feldspar lithic sandstone, and sedimentary tectonics have diverse forms. On the basis of deposition microphase analysis, the sand bodies’ planar distribution characteristics under phase-controlled conditions were analyzed using a seismic model inversion technology to provide theoretical guidance for oilfield expansion, exploration, and exploitation.

The study aims to analyse whether the unemployment, poverty and education factors affect gross Regional domestic product (GDP) in Merauke Regency in 2010-2018. The data used in this study is secondary data. The method of collecting data using secondary data from the official data is issued by the Department of Statistics Central of Merauke District. For data processing is done using SPSS 21 program.
 The results of this study showed the variables of unemployment, poverty and education for the four districts studied; The slope district, Kurik District, Naukenjerai District and Sota district are simultaneously affecting the value of the gross Regional domestic product (GDP) of Merauke Regency. Result coefficient of determination (R²) 91.7% indicates that the variables of unemployment, poverty, and education have a significant influence on the improvement of the gross Regional domestic product (GDP). From the results of this research can also be concluded that the unemployment variables that affect the change in the value of gross Regional domestic product (GDP) in Merauke District lower education impact on the gross Regional domestic product value ( GDP) is because awareness of the importance of education in this district is still minimal especially in four districts that are carefully

다중 배제분석을 이용한 강원도 내 풍력발전단지 유망후보지 선정

Promising onshore wind farm sites in Gangwon province of Korea were investigated in this study. Gangwon province was divided into twenty five simulation regions and a commercial program based on Reynolds averaged Navier-Stokes equation was used to find out wind resource maps of the regions. The national wind atlas with a period 2007-2009 developed by Korea institute of energy research was used as climatologies. The wind resource maps were combined to construct a wind resource map of Gangwon province with a horizontal spatial resolution of 100m. In addition to the wind resource, national environmental zoning map, distance from substation, residence and automobile road, Beakdudaegan mountain range, terrain slope, airport and military reservation district were considered to find out promising wind farm sites. A commercial wind farm design program was used to find out developable wind farm capacities in promising wind farm site with and without excluding environmental protection regions. The total wind farm capacities with and without excluding the protection regions were estimated to be 46MW and 598MW, respectively, when a 2MW commercial wind turbine was employed.

Early Image Representation by Slope Districts

Based on the topographic description of slope districts, images can be segmented into a set of regions that is invariant to uniform monotonic scalings of the image. Whereas most previous work relating to slope districts has been restricted to ideal continuous smooth surfaces, this paper describes a robust technique for extracting slope districts from discrete images which is insensitive to variations in the topology of the image. In addition, the image is smoothed over a range of scales to produce a hierarchical description in terms of linked slope districts. At each scale the slope districts are described by attributes such as their image curvature, edge location, and gray-level volume. This image representation is intended as input to subsequent stages of image analysis such as feature grouping and model matching.

Early image representation using regions defined by maximum gradient paths between singular points

A representation for images is described that is intended to be interposed between the pixel data and Marr's primal sketch. The image is segmented into regions named slope districts which are defined by maximum gradient paths between singular points. A rich data structure is formed containing the regions, their boundary components, overall attributes, and relationships with their neighbours. This representation provides a framework to simplify the interaction between bottom-up and top-down processes. Examples are given using simple grouping rules to construct more complex elements like those in the primal sketch.

Three-Dimensional Shape Description Using the Symmetric Axis Transform I: Theory

Blum's two-dimensional shape description method based on the symmetric axis transform (SAT) is generalized to three dimensions. The method uniquely decomposes an object into a collection of sub-objects each drawn from three separate, but not completely independent, primitive sets defined in the paper: width primitives, based on radius function properties; axis primitives, based on symmetric axis curvatures; and boundary primitives, based on boundary surface curvatures. Width primitives are themselves comprised of two components: slope districts and curvature districts. Visualizing the radius function as if it were the height function of some mountainous terrain, each slope district corresponds to a mountain face together with the valley below it. Curvature districts further partition each slope district into regions that are locally convex, concave, or saddle-like. Similarly, axis (boundary) primitives are regions of the symmetric surface where the symmetric surface (boundary surfaces) are locally convex, concave, or saddle-like. Relations among the primitive sets are discussed.

Two-Dimensional Critical Point Configuration Graphs

The configuration of the critical points of a smooth function of two variables is studied under the assumption that the function is Morse, that is, that all of its critical points are nondegenerate. A critical point configuration graph (CPCG) is derived from the critical points, ridge lines, and course lines of the function. Then a result from the theory of critical points of Morse functions is applied to obtain several constraints on the number and type of critical points that appear on cycles of a CPCG. These constraints yield a catalog of equivalent CPCG cycles containing four entries. The slope districts induced by a critical point configuration graph appear useful for describing the behavior of smooth functions of two variables, such as surfaces, images, and the radius function of three-dimensional symmetric axes.
