CO2 pre-injection fracturing is a promising technique for the recovery of continental shale oil. It has multiple advantages, such as oil enhancement, geological storage and water consumption reduction. Compared with conventional huff puff flooding, features higher injection rates pressures, leading to EOR improved performance. Combining physical experiments numerical simulation, this research systematically investigated performance in reservoirs. The results showed that greatly recovery; after seven cycles soaking, average factor was 39.27%, representing relative increase 31.6% compared puff. With increasing pressure, solubility grew both water, so did adsorption shale. Numerical simulation indicated ratio production stage 76.46%, which validated effectiveness terms storage.

The recovery of heavy oil is challenging due to its high viscosity. Especially in water flooding, the viscosity induces a water/oil mobility ratio, resulting frequent channeling and fingering. In present work, reduction caused by foaming agents studied. Among studied foam systems, KX-048 agent had best performance. It also shows excellent performance, including large volume, long half-life, comprehensive index. With viscosity, decreases foam/oil 0.28, which beneficial for controlling gas fingering flooding. Moreover, Foam flooding experiments heterogeneous sand-pack models indicate that has efficiency improving recovery, especially low-permeable tube. chosen could provide promising pathway recovery.

In order to develop precise hole placement technology for gas extraction, this paper combines industrial testing, the evolution law of coal rock damage permeability, and double-pore double-permeability model; establishes a coupling model deformation field matrix-fracture double diffusion seepage field; determines spacing seam by using COMSOL Multiphysics 5.6 numerical simulation software. This study shows that effective radius extraction is 4.8 m after 180 d which power function time. The permeability body affected matrix adsorption, contraction stress, influence range between boreholes under multi-hole increases with increase in spacing; at same time, we took into account positive effect change on ultimately determined optimal Dashucun Mine be 6 m, was arranged square area. good on-site test, results can provide guidance arrangement underground areas mines.

This study proposes a model for transient stability assessment, which is convolutional neural network combined with saliency map (S–CNN model). The trained on dynamic data acquired through the measurement devices of power system. Applying to visually highlights critical aspects assessment. reduces training time by eliminating unnecessary during training, thus improving efficiency. As result, proposed can achieve high performance in are configuring benchmark models, IEEE 39 and 118 bus systems, MATLAB/Simulink performing time-domain simulations. Based data, verified confusion matrix. Furthermore, an analysis effects noise interference conducted.
