Previously, we showed that high-energy metabolites (lactate and ketones) “fuel” tumor growth experimental metastasis in an vivo xenograft model, most likely by driving oxidative mitochondrial metabolism breast cancer cells. To mechanistically understand how these affect cell behavior, here used genome-wide transcriptional profiling. Briefly, human cells (MCF7) were cultured with lactate or ketones, then subjected to analysis (exon-array). Interestingly, our results show treatment increases...
The oil production rate decreases rapidly after a short period of high yield from acidizing or fracturing in low-permeability reservoirs. In this paper, nanospheres are applied before the step, which possess ability to absorb water and expand layer, reducing flow capacity bottom finally enhancing recovery. plugging performance is investigated by nanosphere displacement experiments cores sand-packs, explores effect oil-water transition zones, layer zones. addition, nuclear magnetic resonance...
Abstract In regions of the nitrogen limited low latitude ocean, phosphate can also be depleted to levels initiating stress responses in marine microbes. Here, we associate a broad region depletion subtropical North Pacific with different phosphorus stress. Nutrient and aerosol addition experiments demonstrated primary limitation bulk phytoplankton community, supply aerosols relieving this limitation. At northern sites phosphate, alkaline phosphatase activities were enhanced, indicating...
Robustness of complex networks has attracted much attention in diverse disciplines. Most previous studies did not consider the attack cost. In this paper, network robustness is studied with consideration cost, different models and indices. It found that cost function budget, best strategy changes. When budget low attacking hubs costs more than an unimportant node, then high-degree (HDA) performs worse low-degree (LDA) strategy. On contrary, HDA always a better when high. Therefore, there...
Abstract Huge oil reserves are located in low-permeability reservoirs the Ordos basin China. These have three key characteristics: low reservoir quality (10 to 13% porosity), permeability (0.3 2.0 md), and pressures (pressure gradients of 0.0075 0.009 MPa/m). Fracture stimulation is essential for commercial production these reservoirs. To better understand fracture growth behavior optimize treatment designs, microseismic monitoring modeling were performed pilot wells areas. In some basin,...
Abstract The Changqing field is one of the largest fields in China, yet it characterized by low permeability, initial pressure, and reservoir quality. During past few years, technological advancements within oil industry, horizontal drilling, hydraulic fracture stimulation have helped create a development boom this field, with total production barrel equivalence (BOE) reaching 50 million tons 2013. Located Ordos basin primary pay formation Triassic, which features complicated sedimentary...
Traditional methods to identify the important nodes are suitable for single networks. However, many real-world networks coupled together, which can be modeled by multi-layer Therefore, traditional identification may not In this paper, we propose a new method in logistic network. Considering dynamic of network, routing strategy based on greedy algorithm and iterative is proposed. The betweenness centrality closeness modified according show traffic condition topology characteristics each node....
Abstract When cold fluid is injected into low-temperature, low-pressure, low-permeability reservoirs containing wax-bearing heavy oil, cryogenic paraffin deposition and oil condensation will occur, thus damaging the formation. Moreover, formation pressure coefficient low working flowback efficiency low, which affects fracturing stimulation effect. Therefore, an in situ heat/gas clean foam system proposed. This can ensure that conventional create fractures carry proppant reservoir, generate...
Abstract The Changqing field consists of many individual oil fields that stretch across a large area in the Ordos Basin north central China. Oil reservoirs typically consist stacked sand/shale deposits with majority target zones having low permeabilities 0.05 to 0.3 mD. All wells completed these tight are fracture stimulated achieve commercial production. Fracture stimulation is also commonly done injection enhance injectivity under waterflooding. In successful water program, it critical...
URTeC 1578201 Ultra-low permeability reservoirs in the Changqing Oilfield exhibit low reservoir quality (porosity of 9-12%), (0.05 to 0.3 mD) and pressure (about 75 85% normal hydrostatic pressure). Due these conditions restrictions well spacing waterflooding patterns, it is not effective achieve economic production by simply increasing fracture lengths using conventional stimulation techniques. An operator has conducted theoretical studies pilot field trials, integrated characteristics into...
Abstract The Chang7 group in Ordos Basin usually shows low brittleness index, high differential principle stress and little natural fracture, which makes it difficult to generate complex fractures with traditional rate hydraulic fracture practice. During a geomechanical test on core samples, were unexpectedly found inside the sample due fatigue failure after cyclical loading below gradient. Based cyclic tests cores large-scale mockups, fracturing technology was developed specific operation...
The coupling relationship between the deformation field, diffusion and seepage field is an important factor in fluid transport mechanisms long-term coalbed methane (CBM) exploitation process. A mathematical model of gas–water two-phase fluid–structure a double-porosity medium coal reservoirs established this paper. Taking Hancheng Block, typical production block Qinshui Basin, as geological background critical desorption pressure, reservoir permeability anisotropy considered model. COMSOL...
During froth flotation, the separation of chalcopyrite from molybdenite is hindered by their similar surface properties. Therefore, it imperative to develop an efficient selective collector with innovative minerophilic groups and reduce use inhibitors. In this study,5-methyl diethyl dithiocarbamate-1,3,4-oxadiazole-2-thione (MDCODT) was first introduced as a in flotation molybdenite. Micro-flotation experiment results expressed that selectively could be realized without addition inhibitor....
