During the drilling of natural gas hydrate reservoirs, invasion may occur, which has an adverse impact on upward return process cuttings and control bottom-hole pressure. A multiphase fluid CFD simulation method based Eulerian model was optimized. With help Fluent 23R1 software, simulations three-phase flow fluid–cuttings–invaded in vertical section, build-up horizontal section complex annulus wellbore particle dynamics were carried out. The characteristics after revealed, impacts deposition...
An effective Max-Fire CNN model MF-SarNet for synthetic aperture radar (SAR) automatic target recognition (ATR) is presented, here. By selecting the convolution kernel of Fire module in network, parameters are reduced to obtain convolutional neural network less parameter. In view requirement deep learning large-scale data, an augmentation method proposed, which can learn features large database better. The results based on MSTAR show that and result encouraging. accuracy SAR image 98.53%.
Accurately predicting delays for high-speed railways (HSRs) is a challenging yet significant task. The historical operation data of the HSRs, implicating delay derivation rules under dispatchers' rescheduling strategies, have sparsity characteristics, resulting in heterogeneous prediction performances different scenarios. This article proposes Gaussian noise augmentation-based method to cope with sparsity. Specifically, added original based on train characteristics. Then, rather than...
Abstract Formation gravity displacement refers to the phenomenon of "overflow and leakage" in same crack due difference density between drilling fluid formation fluid. In order restrain leakage accident caused by displacement, this paper studies window, conditions puts forward corresponding solutions. summary, develops wellbore-formation experimental device, carries out gas-liquid critical point experiments, summarizes analyzes fits pressure curve window based on results constant...
