Abstract: Hongliugou-Lapeiquan ophiolitic mélange belt, which is exposed in the northern margin of the Qinghai-Tibet Plateau, has been providing significant information for the deep study of Early Paleozoic tectonic framework and evolution of North Altun. On the basis of detailed geological mapping and struct...
Abstract: The eastern Junggar Basin has undergone multiple tectonic movements. Its tectonic characteristics, formation and evolution mechanism are of great guiding value for oil and gas exploration and development in this area. By using high-resolution 2-D and 3-D seismic and well logging data, ten geological...
Abstract: The continuous collision and compression between the Indian plate and the Eurasian plate during the Cenozoic period led to a strong intraplate deformation of the Asian continent, which resulted in the formation of a triangle deformation area and strong earthquake activity area, namely the Xinjiang-T...
Abstract: The theory of elastic mechanics is applied to find out distribution and dynamic evolution of stress field in the forming process of fold structure. The analytical expression of stress field when a single fold starts is deduced, through which the relationship between fold wavelength and the thickness...
Abstract: Ground stress is the basic parameter for oil and gas reservoir evaluation. The traditional solution of ground stress of single well usually relies on logging data and rock mechanics experiments, without considering the effect of formation rock heterogeneity on ground stress in the whole mechanical m...
Abstract: The development of the Cenozoic cap rock in the western Bohai sea area is closely related to hydrocarbon accumulation. In order to clarify the control of cap rock on hydrocarbon enrichment, based on the drilling data, logging data and coring analysis data, the development characteristics of the Ceno...
Abstract: The Delingha depression is an area with prospects for Carboniferous exploration in the Qaidam Basin. The Main tectonic movement periods in the Qaidam Basin were obtained based on the comprehensive regional survey, balanced profile inversion, and vitrinite reflectance. Base on the basin simulation te...
Abstract: Shale gas exploitation requires large-scale artificial hydraulic fracturing of resevoirs. In order to study the variation law and mechanism of shale permeability during fracturing, fluid-solid coupling physical simulation experiments on two shale samples with and without filled natural fractures wer...
Abstract: The article aims to analyze the organic geochemistry and inorganic mineral characteristics of the Lower Cambrian Niutitang Formation shale in northwestern Hunan Province. The main research methods include carbon-sulfur measurement method, rock pyrolysis method, chloroform asphalt "A" measurement met...
Abstract: Located in the geothermal anomaly area along the southeast coast of China, the Heyuan fault zone in Guangdong Province owns abundant geothermal resources. To investigate its potential, the mechanics and tectonic relationship to the geothermal field of the Heyuan fault zone in Guangdong Province are ...
Abstract: Buried ground-fissrues have the potential disaster effects and the randomness of expansion, and surface water is one of the factors that induce the expansion of buried ground-fissrues. Based on field investigation data, two main expansion mechanisms, hydraulic pressure and the loess collapsibility, ...
Abstract: The pollution of geomaterials is one of the key problems in construction. Considering proportion of lignin fibre, laboratory mechanics experiments and SEM tests were applied to natural red clay and lignin fibre-adding red clay. Variation laws of strength characteristics and effects were studied when...
Abstract: Hefei is located in the north bank of the middle and lower reaches of the Yangtze river and Xiashu loess is widely distributed. Through the analysis of lithology, oxide content and geochemical weathering parameters of BK2 borehole section in Hefei area, the geochemical characteristics and climate ch...
Abstract: The mafic-ultramafic rocks in Paleo-Tethys domain of East Kunlun are not well documented. Researches on petrography, geochronology and geochemistry of the olivine pyroxenolite in Xiwanggou mafic-ultramafic intrusion, located in the Eastern Section of East Kunlun in Qinghai Province, can provide new ...
