A systematic CT-scan-aided laboratory study of N2 foam in Bentheimer sandstone cores is reported. The aim the was to investigate whether can improve oil recovery from clastic reservoirs subject immiscible gas flooding. Foam generated situ water-flooded by coinjecting and surfactant solution at fixed quality. It stabilized using two surfactants, namely, C14–16 α-olefin sulfonate (AOS) mixtures AOS a polymeric fluorocarbon (FC) ester. effects concentration, injection direction, preflush, core...
Summary A detailed laboratory study of nitrogen-foam propagation in natural sandstones the absence oil is reported. The goal this was to elucidate further mechanisms foam mobility control. C14–16 alpha-olefin sulfonate (AOS) surfactant selected stabilize foam. X-ray computed-tomography (CT) images were taken during map liquid saturation over time. Effects concentration and total injection velocity examined detail because these are key parameters for controlling strength under field...
For the purpose of investigating dynamic deformational behavior and failure mechanisms magnesium under high strain rates, Split Hopkinson Pressure Bar (SHPB) was used for mechanical properties extruded Mg-Gd-Y Magnesium alloy at ambient temperature (300 K), 200 °C (473 K) 300 (573 temperature. The samples after compression were analyzed by scanning electron microscope (SEM) metallographic microscope. Dynamic properties, crack performance plastic deformation mechanism along extrusion...
Abstract We present an experimental and numerical study of the mechanism hydraulic fracturing in unconsolidated rocks. performed experiments on loose sand samples under various confining pressures. have developed a large biaxial set up which cylindrical dimensions 0.4×0.51 m can be tested stress to 40 MPa. prepare sample by pouring into vessel, is filled with water obtain fully saturated sample. There borehole (injection system) open section middle vessel. The closed during preparation....
Abstract A systematic CT scan aided laboratory study of N2 foam in Bentheimer sandstone cores is reported. The aim the was to investigate whether can improve oil recovery from clastic reservoirs subject immiscible gas flooding. Foam generated in-situ water-flooded by co-injecting and surfactant solution at fixed quality. It stabilized using two surfactants, namely C14-16 alpha olefin sulfonate (AOS) mixtures AOS a polymeric fluorocarbon (FC) esther. Effects concentration, injection...
Impact force refers to a transient phenomenon with very short-acting time, but large impulse. Therefore, the detection of impact vibration is critical for reliability, stability, and overall life mechanical parts. Accordingly, this paper proposes method indirectly characterize by using an stress wave. The LS-DYNA software utilized establish model ball impacting steel plate, response point are obtained through explicit dynamic finite element analysis. In addition, on basis, correspondence...
Abstract We have conducted laboratory tests to investigate the containment of hydraulic fractures in unconsolidated, layered formations. varied both permeability and strength layers samples. The fracture evolution was observed with X-Ray CT scanning by excavating sample after test. found that is dominant factor containment, if stress contrast small. With a three four between two there strong tendency for propagate low layer. Difference much less important containment. A numerical propagation...
Optimizing alloy composition is an effective way to improve the microstructure and properties of superalloys. Herein, influence carbon content (0.071, 0.105, 0.136 wt%, respectively) on mechanical GH3230 formed by laser melting deposition investigated. The results indicate that contents affect quantity, morphology, distribution carbides in matrix alloy. As increases, number morphology at grain boundaries changes from discontinuous blocks chains, finally into strips. Three alloys with high...
In this study, experiments were conducted to make a comparison in bromate formation between KMnO4/O3 combined oxidation and single ozonation. The effect of KMnO4 dosage, temperature, pH NOM on during was investigated. Result shows that, is 26% lower the process oxidation. optimal dosage suggested be 1mg/L considering balance inhibition residual manganese concentration. When 1.0mg/L, initial bromide concentration than 80 μg/L, temperature below 25°C, can under maximum contaminant level 10...
Coiled tubing (CT) has been widely used for oil and gas exploitation, however corrosion of CT under high pressure temperature (HPHT) environment was often reported, also induced failures welds were observed to occur during service. Corrosion related behaviors are not clear. Therefore, a study the resistance HPHT is carried out. In order efficiently evaluate welds, some test samples obtained by linear cutting out CT110 in service on site. The water from field as reagent simulate actual...
To solve the existing problems of traditional bridge vibration (BV) data compression methods, on basis deep analysis for wavelet transform (WT), a method combined with LZW coding is proposed in this paper. In accordance characteristics and properties transform-based multi-resolution analysis, Donoho threshold algorithm adopted to quantify high-frequency decomposed components. Then are compressed improved coding. justify method, several groups actual sampling simulated. The results indicate...
