Abstract: The Standard Lattice Model predicts that under high stress, the outer most electrons of the Si-O bonds of a rock get ejected into the lattice's interstitial space. This loosely bound exoelectron cloud will, in a battery's electric field, have a direct current (DC) I; it will also absorb electromagne...
Abstract: In order to find out the in-situ stress state near the Penglai coast, hydraulic fracturing in-situ stress measurement was conducted in two boreholes (less than 200 meters in depth). The results were compared with the in-situ stress state of three boreholes off Changdao. Regression analysis was adopt...
Abstract: Crustal stress is an important index of reservoir reconstruction scheme design and improvement to oil and gas exploration and development efficiency. Due to the complex environment in which tight reservoirs are located, the multi field coupling of temperature, stress and seepage should be considered...
Abstract: The understanding of seepage characteristics of low-permeable reservoir is of great significant for oil and gas production and reservoir reconstruction. Therefore, the micro CT scanning technology was used to scan the tight sandstone samples so as to establish a microscopic model that can accurately...
Abstract: Fracture is an important factor affecting the high and stable yield of reservoir, which lies in a complex geological environment. The formation and development of fractures are influenced by numerous factors; therefore, it is of great significance to study the effect of coupling among factors on res...
Abstract: Reservoir rock brittleness evaluation is important foundation work for the design of reservoir fracturing reconstruction scheme, which has great influence on reservoir fracturing reconstruction effect. Taking the deep tight sandstone reservoir in the central part of the Junggar Basin as the research...
Abstract: The Gonghe Basin is rich in hot dry rock geothermal resources. In order to enhance the theoretical understanding of the genesis of hot dry rock geothermal resources in the Gonghe Basin and further promote the exploration of hot dry rock resources, a comprehensive analysis of the genesis of hot dry r...
Abstract: Evaluation of reservoir fractability is an important basis for reservoir reconstruction, and the main factors affecting the fracability of tight sandstone are natural fracture, sandstone brittleness, horizontal stress difference, fracture toughness and so on. Taking Jurassic tight sandstones in Well...
Abstract: The Ordovician reservoirs in H gas field of Bachu uplift in Tarim Basin are carbonate reservoirs with low porosity and low permeability. The fracture system, as reservoir percolation channel, is characterized by complex spatial distribution and main control factors, and features of multi-stage super...
Abstract: The velocity, accumulation characteristics and energy conversion are important factors in the study of the disaster-causing mechanism of high-speed and long-stance landslide; however, model test and field investigation can't fully reveal the mechanism. In this study, the landslide in Sanxicun was si...
Abstract: Due to special geological conditions and regional geotectonic settings, several strong earthquakes occurred in Xiji county, Ningxia province in history, which induced a large number of loess-mudstone interface landslides, and brought serious threat to the safety of local people's life and property. ...
Abstract: Shaanxi Province is one of the provinces with the most serious geological disasters in China, especially the Qinling-Daba mountain area in south Shaanxi Province. Therefore, it is of great significance to conduct geological hazard assessment to guide disaster prevention and reduction. Taking Qinling...
Abstract: There are a large number of potentially dangerous loose slag accumulation bodies in Xuanhua area of Zhangjiakou. The representative Xiangshuigou loose slag accumulation bodies in the area is taken as the research object, and the laboratory tests are made on particle composition, mineral composition ...
Abstract: The cross-Bohai Strait passage is not only an important traffic and transportation project which connects Shandong Peninsula and Northeast regions, but it is also of vital significance for promoting the economic development of the Bohai-ring and revitalizing the northeast old industrial base. For th...
Abstract: There exist a number of Jinningian magmatic rocks in Xixiang county, Shaanxi Province, which is an important "fingerprint" to study and understand the evolution of the Yangtze craton basement. This paper focuses on gabbro body, granite and albitophyre dikes from Longwangtang region, aiming to unders...
Abstract: The paper reports a mid-Cambrian granitic magmatic activity which is comprised of gneissic granodiorite and monzogranite in Maeryang area of Tashkurgan massif, West Kunlun. LA-ICP-MS zircon U-Pb dating yields the emplacement ages of ca. (506.0±6.8) Ma and (514.0±9.3) Ma, respectively. The granites a...
