Abstract This study presents the validation of a dynamic test system to simulate high‐speed train passing bridges under seismic excitation. The comprises scaled models CRH380A and an 11‐span simply supported bridge on shake table array. innovative apparatus combines loading with moving load replicate train‐track‐bridge interaction (TTBI) during earthquakes. It allows investigation various speeds excitations, providing invaluable insights into TTBI. First, detailed similarity design principle...
In order to prevent steam breakthrough and improve thermal efficiency in the process of SAGD development oil sands by real-time adjustment on injection-production temperature difference (Subcool) according growth situations chamber along wellbore, a series studies were conducted coefficients optimization proportional-integral-derivative (PID) control equation for steam-liquid level intelligent model. According heat conservation material balance principles, mathematical model determining PID...
Wormlike micelles formed by amidosulfobetaine surfactants present advantage in increasing viscosity, salt-tolerance, thermal-stability and shear-resistance. In the past few years, much attention has been paid on rheology behaviours of that normally bear C18 or shorter tails. Properties oil displacement performances wormlike counterparts bearing long carbon chain have not well documented. this paper, various properties C22-tailed surfactant EHSB under high salinity (TDS = 40g/L) are...
Abstract Compared with conventional hydraulic fracturing, radial-drilling fracturing presents remarkable advantages and can effectively develop low-permeability reservoirs. The radial borehole reduce formation fracture pressure guide the initiation propagation. Due to large azimuth or strong anisotropy of reservoir, single may not efficiently researchers proposed multibranched fracturing. However, research on is inadequate. Radial boreholes usually need certain dip angles avoid penetrating...
Abstract Steam assisted gravity drainage (SAGD) process is widely used in super heavy oil and sands projects. These projects generally have higher steam to ratio poor economy, partly because un-uniform chamber along the horizontal section forms it hard adjust, affecting by reservoir heterogeneity including muddy interlayer thief zones. Therefore, desirable explore realistic promising technology measures for SAGD at low price. In this paper, almost all were extensively deeply investigated...
The pulse effect of near-fault ground motion has asevere threat to high-speed railway train running on bridge. Current research generally relies numerical simulation and lacks physical test data. In this paper, a scale indoor bridge is conducted dynamic characteristics train–track–bridge system under pulse-type are explored. the excited by shaking table with lateral inputs motion, pulse-free far-field motion. A corresponding model established validated Then, influence regularities response...
Abstract Non-uniform steam chamber caused by reservoir heterogeneity, shale interlayer, local mobile water, undulating well trajectories and improper operation, etc., severely restricts oil sands SAGD performance. Inflow control devices (ICD) achieved great success in controlling conventional water or gas coning. Inspired this, liner then retrofitting tubing deployed ICD have been tested since 2009 soared recent years. Therefore, this paper made a systematic review of design, operation...
Hot solvent-assisted gravity drainage (HS-AGD) is an effective way to exploit oil sands and heavy both economically environmentally. The visualized microscopic seepage experiments two-dimensional (2-D) macroscopic simulation of HS-AGD are carried out, the results compared with that steam-assisted (SAGD) in detail for first time order compare their development effects sand reservoir. MacKay River bitumen taken as sample experiments, n-hexane solvent. Micro characteristics hot solvent steam...
Abstract Compared with conventional wet saturated steam, both enthalpy and specific volume of superheated steam are much larger. Combination as injected media SAGD process is expected to improve development effect oil sands less consumption. In this paper, performance in certain project considering aquathermolysis reactions mechanism was evaluated compared by physical simulation, theoretical analysis numerical simulation for steam. Superheated enhances recovery a little under the same heat,...
The existence of the bottom oil–water transition zone (BTZ) greatly impairs performance conventional steam-assisted gravity drainage (SAGD) process and its mitigation measures are very limited. In order to accelerate oil production decrease Steam-to-Oil Ratio (SOR), a promising technology involving steam drive (SDGD) by placing dual-horizontal wells with high permeability in BTZ was systematically studied. This paper conducted two-dimensional (2D) three-dimensional (3D) physical simulations...
With further progress of Steam-Assisted Gravity Drainage (SAGD) technology, a growing number oil sands or heavy reservoirs were put into production in an efficient way. However, owing to the existence muddy laminae within reservoirs, there are challenges associated with expansion steam chamber and drainage during SAGD process. The purpose this study is evaluate adverse impact on conventional performance introduce improvement strategy multilateral well patterns reduce improve performance. In...
Abstract Steam assisted gravity drainage (SAGD) using parallel dual-horizontal wells made great success in developing heavy oil or sands projects. However, the performance may be greatly impaired when shale laminae with high frequency exist. In order to enhance production and decrease steam ratio (SOR), this paper conducts feasibility study of offset well pair drive develop project by overcoming laminae. Physical simulations pairs under three horizontal distance were first carried out...
