Analytical Solution of Steady-state Temperature Field of Asymmetric Frozen Wall Induced by Directional Seepage

工程科学与技术, 2022
Due to the superposition of convection heat transfer of water flow and heat conduction of freezing pipes, the shape of the artificial frozen wall was obviously asymmetrical under the action of the seepage field. To solve the difficulty in the calculation

Principle of relationship between seepage movement and action

Scientific Reports, 2022
The seepage is completed under the control of the action. There is a definite relationship between the seepage and its controlling factors. The recharge flow, seepage flow and water level change are unified.

TAMNet: Temporal and adaptive‐frequency network with MixStyle for cross‐region oil and fluid production forecasting

Deep Underground Science and Engineering, EarlyView.
This paper presents temporal and adaptive‐frequency network with MixStyle (TAMNet), a deep time‐series modeling framework for accurate and robust multi‐well oil productivity forecasting. TAMNet integrates transformer and long short‐term memory architectures to capture both short‐ and long‐term temporal dependencies, enhanced by a temporal gate unit ...

Mechanistic study on the effect of seepage force on fracture propagation behavior in multi-cluster fracturing of horizontal wells

Petroleum Research
During multi-cluster fracturing of horizontal wells, low-viscosity fracturing fluid permeates extensively along the fracture walls into the rock pores, exerting seepage forces on the rock skeleton.

Multi‐factor coupling effects in hydraulic fracturing of laminated shale: Experimental insights and physics‐informed neural network‐driven optimization

Deep Underground Science and Engineering, EarlyView.
This study establishes a multi‐factor coupling framework for predicting breakdown pressure in laminated shale by integrating experimental hydraulic fracturing tests, physics‐informed neural networks (PINNs), and Sobol sensitivity analysis. It reveals how differential stress, the bedding dip angle, and the injection rate interact to influence fracture ...

Exponentially‐constrained Gaussian mixture model for quantifying vertical development of water‐conducting fracture zones in lithologically stratified mining roofs

Deep Underground Science and Engineering, EarlyView.
This study proposes an exponentially‐constrained Gaussian mixture model (EcGMM) to quantify vertical fracture heterogeneity in stratified roof strata. The model integrates a piecewise exponential decay term capturing global stress dissipation with Gaussian components representing localized fracture intensification at lithological interfaces.

Sotka Dam Seepage; Evaluation and Possible Remediation

Sulaimani Journal for Engineering Sciences, 2016
One of the most important analysis that should be done before the construction of an embankment dam is the seepage analysis. Inaccurate analysis of the seepage through the foundation or the dam body will lead to inaccurate design of the seepage control ...
