Abstract: Qikou Depression has developed many types of slope structures, which are the main enrichment areas of stratigraphic and lithologic reservoirs.Banqiao slope is a rotating tilting slope controlled by boundary faults in the western margin of Qikou Depression, and its fracture characteristics are comple...
Abstract: The study on provenance identification of Bohai Bay Basin is great significance to its evolution, the uplift and erosion process of the peripheral orogenic belt, and the material diffusion of the continental shelf sea in eastern China.K-feldspar is one of the most important petrogenic minerals in th...
Abstract: The amount of discovered resource is not in consistence with resource evaluation results at all, which leads to little significant breakthrough in tight gas exploration of the Lower Carboniferous in Marsel block of Kazakhastan.Based on the analysis of high frequency sequences, well logging, oil test...
Abstract: The western Guizhou is located at the southwest margin of the Yangtze Block.The record of 2.5 Ga magmatic events in the Yangtze Block is very little.The Hezhang quartz monzodiorite recently discovered in western Guizhou shows that the LA-ICP-MS U-Pb age of the rock is (2 542±9)Ma, which is the first...
Abstract: Based on analyzing the grain size of a red earth profile in Yong'an, which is the first discovery of red earth in western Fujian province, and comparison of grain size result in Yong'an, typical eolian deposit, modern fluvial sediment and red earth in other areas, the causes of the red earth in Yong...
Abstract: The resources of the Fuyu reservoir in the Daqing Oilfield are abundant. Due to the unclear characteristics of reservoir and lack of scientific sweet classification scheme, it is difficult to optimize the sweet in the study area. In order to clarify reservoir characteristics and sweet selection sche...
Abstract: The Tonglüshan copper-iron (gold) deposit is a typical skarn deposit in the middle and lower reaches of the Yangtze River in Hubei.In order to find the origin of skarn, the petrographic observation, microscopic temperature measurement and laser Raman analysis of the inclusions were carried out.The r...
Abstract: As a product of hydrothermal activity, seabed polymetallic sulfides have good prospects for mineralization and development potential, and it has become the focus of marine mineral exploration in various countries.Fuzzy analytic hierarchy process (FAHP), which combines fuzzy mathematics with expert k...
Abstract: In order to reveal the distribution rule and main controlling factors of crude oil from the Es3 and Es4 source rocks in Bonan Sag, group separation, gas chromatography (GC) and gas chromatography-mass spectrometry (GC-MS) and other means were used to analyze the geochemical characteristics of crude ...
Abstract: The exploration of carbonate "fault-karst" reservoirs in Ordovician strike-slip fault zone in Shunbei area of Tarim basin has become a hot spot recently.Multiple drilling wells in Shunbei area of Tarim Basin show that the fault zone and fracture development site generally have unusually high natural...
Abstract: The southeastern margin of the Yangtze block is an important Pb-Zn metallogenic belt in China, however, the systematical research of Fenghuang ore field is still in progress. Taking the deposit as the research object, the characteristics, source and composition of ore-forming fluid were studied by m...
Abstract: In order to study the residual strength of the loess-gravel interface, this paper investigated the residual strength of the loess-gravel interface with different water content by improved ring shear tests, what's more, the scanning electron microscopy (SEM) was taken to study the microstructure of t...
Abstract: In recent years, during urban engineering, there have been frequent karst collapses in Wuhan city, which seriously affects urban development and citizens security. In order to ascertain the susceptibility zone of ground collapse in karst area and put forward prevention measures, the Baishazhou karst...
Abstract: Drawing up scientific zoning maps of landslide susceptibility can effectively reduce the loss caused by disasters.Taking Mangshi City, Yunnan Province as the research area, the researchers used certainty factor (CF) method to calculate the sensitive values of each factor, and used them as classified...
Abstract: Deformation and failure of reservoir landslide are affected by creep properties and environmental factors ofits rock and soil.Therefore, it is of great significance to study the creep properties and stability of landslide.In order to study the creep characteristics and stability of landslide rock an...
Abstract: Taking shallow groundwater of shayang-jiukou area in Jianghan plain as the research object to evaluate shallow groundwater vulnerability of Jianghan plain, is directed against the shortcomings of the traditional DRASTIC model, suchas strong relevance and weight subjectivity of evaluation indexes, di...
Abstract: Shallow confined aquifer is the main groundwater exploitation layer in the West of Dongting Plain, but it is faced with serious water shortage owing to worse water quality, among which ammonium anomaly is the most typical.However, its source and enrichment mechanism has been poorly understood at pre...
Abstract: Eleven sandstone samples from Benxi Formation of Upper Paleozoic in Gaoqiao area of Ordos Basin were selected.The lithological characteristics and pore structure characteristics of the reservoir were analyzed based on rock slices and scanning electron microscopy.The distribution data of nuclear magn...
Abstract: In the construction and operation of tunnels such as highways, railways, water conservancy and hydropower, and mines, it is inevitable to encounter geological disasters such as collapse and water inrush. The instability and destruction of surrounding rocks and seepage sudden change are the direct ca...
Abstract: The fracture type, development and distribution characteristics of organic-rich mud shale are important factors that affect the accumulation and dissipation of shale gas.Based on core observation and high resolution micro-resistivity image logging (FMI), the fracture development characteristics of t...
