Nanofluid of graphene-based amphiphilic Janus nanosheets produced high-efficiency tertiary oil recovery at a very low concentration (0.01 wt %). The more attractive way is to use nanofluid during the secondary stage, which can eliminate stage and save huge amounts water, especially times when price low. Here, we continue report our findings on application same in recovery, increased efficiency by ≤7.5% an ultralow (0.005 Compared with nanofluids homogeneous nanoparticles, achieved higher...
Traditional methods of exploiting oil shale such as mining or in situ electric heating cause environmental pollution, and they have huge energy losses high costs. These problems can be solved by combining microwave with hydraulic fracturing for the exploitation shale. In this study, an experimental apparatus was manufactured laboratory experiments. Different weight proportions iron oxide nanoparticles (0.1, 0.5, 1 wt %), output power (600, 800, 1000 W), ultimate reaction temperatures (550,...

Abstract A new three‐dimensional fluid‐solid coupling fracture propagation model of synchronous fracturing was established to study the dynamic process simultaneous hydraulic fracturing. In this paper, we used an improved boundary element method and a finite difference method, respectively, for calculating deformation reservoir rock flow fluid during process. The interaction between fractures nature also considered. Sensitivity analysis showed that fracturing, wells attracted each other...
Occurrence and transport are two important nanoscale behaviors in the exploitation of shale gas. Nanopores a realistic organic matrix composed kerogen molecules, which will have great impact on surface-gas interactions gas nanoconfined behavior. Although there previous studies, physics through systems remains ambiguous. In this work, cylindrical nanopore models representing different pore sizes organic-rich were constructed. By applying molecular dynamics simulation method, occurrence...
A new gas transport model for fractal-like tight porous media is proposed by simultaneously considering the microstructural complexity of real media, compressibility gas, and slippage effect. This clarifies mechanisms in media: total flow volume governed weighted addition viscous flow, distribution weighting factor depends on capillary diameter mean free path gas. Based model, a permeability was derived media. The does not have any empirical constants, every parameter has clear physical...
