Electrical submersible pumps (ESPs) face enormous challenges in the petroleum industry while handling gas–liquid two-phase flow. The major difficulty is caused by accumulation of gas bubbles inside ESP-impellers, which results mild to severe degradation pump performance. Therefore, analyze influence entrainment and bubble size, a combination experimental numerical analysis performed on five-stage mixed-flow ESP present study. experiments are first conducted performance under pure water...
Abstract The staged and layered fracturing technology plays an important role in unconventional tight reservoirs. And the gas well completion integration is core component to realize process, which can of acid later drainage production so as reduce secondary pollution reservoir. packer rubber barrel’s performance directly affects long-term effective sealing reliability itself high temperature pressure environment. In this paper, constitutive model tested from curing kettle simulate...
Due to the strong noise, high dimensionality and time-varying characteristics of industrial process data, data-driven modeling faces challenges in feature extraction model interpretability. To address these issues, this paper proposes a new prediction based on adaptive variational empirical mode decomposition-guided (AVEMDG) graph convolutional networks (GCNs). First, each sensor signal is decomposed into high-frequency low-frequency features using decomposition (EMD) effectively capture...
A novel surface morphology for pipelines using transverse microgrooves was proposed in order to reduce the pressure loss of fluid transport. Numerical simulation and experimental research efforts were undertaken evaluate drag reduction performance these bionic pipelines. It found that vortex ‘cushioning’ ‘driving’ effects produced by vortexes main reason obtaining a effect. The shear stress microgrooved reduced significantly owing decline velocity gradient. Altogether, achieved both pipeline...
In order to evaluate the physical and chemical properties of polymer surfactants analyze their oil displacement mechanisms, three types poly-surfactant used in Daqing field were chosen be researched, effects studied using poly-surfactants different viscosity, dehydrating rate, core permeability. The main purpose is determine reasonable range characteristic indexes polymeric surfactant flooding. effect 15 cores was analyzed, rate emulsion, permeability on EOR (Enhanced Oil Recovery) analyzed....
Drill-string axial vibration at the surface technology is proposed to reduce friction between drill-string and borehole wall, improve load transfer efficiency, rate of penetration (ROP), extended-reach limit a horizontal well. An analytical framework utilizing “soft-string” model constructed. The results obtained from numerical simulations reveal that during slide drilling operation, experiences an stick–slip motion, weight on bit (WOB) undergoes periodic oscillations. conventional...
Axial excitation tools (AETs) have the ability to improve slide-drilling efficiency by reducing friction between drillstring and wellbore wall. However, drag-reduction effects are not always satisfactory, excessive vibration may cause failures of downhole in some cases. Thus, a mathematical model was proposed simulate responses drillstring. In model, velocity-dependent is adopted calculate friction-reduction effect. The effect joints on weight bit (WOB) first investigated. simulation results...
Abstract A brand new impact hammer–Axial & Torsional hammer (producing high-frequency axial and torsional forces simultaneously)–has been developed to improve the penetration rates eliminate stick-slip vibrations in deep ultra-deep wells. This paper presents its rock-breaking mechanism evaluates field application effects. Based on finite element method, a numerical model was first proposed investigate processes of single PDC tooth under axial, respectively. The simulation results show...
With high international oil price, the exhaustion of onshore resources and declination gas production in shallow sea, deep water has become important succeeding area worldwide gas. During deepwater development, riser must be used to isolate seawater, circulate drilling fluid, compensate heaving movements string so on. However, with operating depth increasing, loads waves ocean currents on more complex, leading extremely construction risk funds deep-water operations. In this paper,...
The numerical simulation efficiency of large-scale natural gas pipeline network is usually unsatisfactory. In this paper, Graphics Processing Unit (GPU)-accelerated hydraulic simulations for networks are presented. First, based on the Decoupled Implicit Method Efficient Network Simulation (DIMENS) method, presented in our previous study, a novel two-level parallel process and corresponding method proposed. Then, implementation GPU introduced detail. Finally, some experiments provided to test...
