Based on the characteristics of injection-production units in fractured-vuggy carbonate reservoirs, nine groups experiments were designed and performed to analyze interference their influencing factors during water flooding. percolation theory, an inversion model for simulating waterflooding interferences was proposed study influence laws different characteristics. The results show that well spacing, permeability ratio, cave size, location all affect When is located high fractures, or small...
Steam-assisted gravity drainage (SAGD) is one efficient and mature technology for recovering heavy oil bitumen resources. The key underlying mechanism the growth of steam chamber after injecting steam. However, due to complex geological environment, thief zones exist have a prejudicial effect on development chamber, thus impacting ultimate heavy-oil recovery. In this work, our objective investigate top-water zone (i.e., water overlies sand) SAGD performance further understand crucial...
Clothing adjustment by building occupants is a highly effective and prevalent thermal adaptation behavior aimed at achieving comfort. This paper aims to quantify the impact of climate-responsive indoor clothing on heating/cooling energy consumption. A temperature control strategy based rural residents’ was proposed integrated into simulations. Indoor insulations were obtained using predictive model from author’s prior research. These values used calculate setpoint temperatures in terms PMV...
Abstract China is developing rapidly, but there an obvious imbalance in the development level between urban and rural areas. Differences economics, living conditions life style contribute to differences indoor thermal environments, may result perceptions of comfort Clothing insulation as one most important parameters that affect studied this research. A field study conducted areas Lankao, China. total 384 valid samples were acquired. 54.97% researched houses suffered extreme cold...
Composite modified hard asphalt (CMHA) was prepared by four-step high-speed shearing method adding crumb rubber, styrene-butadiene-styrene (SBS) copolymer, and to QHD AH-70 neat asphalt. The high-temperature performance microstructure of CMHA were evaluated rotational viscometer, fluorescence microscopy, infrared spectroscopy, through which the modification mechanism proposed. results show that time had great influence on CMHA. A significant variation in phase morphology during preparation...
The relationship between atmospheric precipitation and water vapor sources is close, so it of great significance to carry out the identification interaction region influenced by different summer monsoons China. Based on wind direction data Global Data Assimilation System, provided National Centers for Environmental Prediction, this study introduces backward trajectory model Hybrid-Single Particle Lagrangian Integrated Trajectory track source rainy season in Southwest It not only quantifies...
Based on the similarity criterion, volcanic rock samples were taken from outcrops to make experimental models. Water flooding experiments of five-spot well pattern, nine-spot relationship between relative and fracture positions, injection rate in dissolution vug-cave reservoirs with/without fractures carried out analyze variation regularities development indexes, find characteristics water with different patterns sort optimal mode. For without fractures, pattern waterflooding has very small...
Abstract LD27-2 block, located in the Bohai Bay, is a heavy oil reservoir with bottom water, average thickness of zone 18m and water five times zone. As viscosity at temperature 1000mPa·s, thermal recovery methods are necessary. Steam flooding has been widely used for worldwide, it can produce significantly faster than cyclic stimulation process, but also have significant economic impact. In order to investigate effect steam experiment simulations performed this study. study, parameters...
Abstract This paper presents an effective decomposition method for multicomponent seismic wavefields. It is assumed in this that the changes of amplitude and phase wavefields adjacent traces are small. In case vertical horizontal components both longitudinal shear waves determined by their different polarization slowness during propagation. Under least square constraint, each wave can be estimated from input data. Therefore, converted reconstructed then separated. accurate. Not only...
Summary Full waveform inversion (FWI) can provide high-resolution velocity models and find more details in velocities than ray-based tomography technologies. However, FWI requires a relatively accurate initial model, data with good low-frequency signal content, an source signature. In our case we successfully apply deep water area of offshore Angola. Our benefits from model created by high-definition variable-depth streamer data, which has accurately estimated signature near-field hydrophone...
Inverse vulcanized polymer materials have received considerable attention as a way to use sulfur, an industrial by-product, starting material for synthesis. The resulting high-sulfur content polymers also been investigated because their properties give rise promising applications like infrared imaging, energy storage, and heavy metal capture due unique structure. However, synthesis of flexible sulfur network which shows good mechanical combining high strength, elongation, toughness is still...
