The corrosion behavior of P110 casing steel in simulated concrete liquid and annulus fluid was investigated to reveal the pattern protective properties products two environments. Potentiodynamic polarization curves, electrochemical impedance spectroscopy (EIS), Mott–Schottky tests, noise (EN) tests were used study saturated with CO2. Scanning electron microscopy (SEM) combined Energy-Dispersive Spectrometer (EDS) mapping characterize morphology elemental distribution steel. results show that...
Interlayer contradiction (high-pressure oil that prevents low-pressure from being extracted) has always been the main factor affecting oil-recovery efficiency of many oil-bearing series in shale wells Eastern Shandong, China. If steps to deal with interlayer are not taken, Shengli Oilfield’s will be significantly reduced after a certain period exploitation. Furthermore, as drilling depth increases, formation-fluid supply capacity Oilfield becomes worse and further increases difficulty...
Due to the widespread application of new technologies such as increased production and injection, output many old wells has improved, but this also led varying degrees sand production. Increased affected oil well production, equipment wear, wellbore plugging, safety risks. To increase particle transport performance within wellbores, indoor experiments have been conducted study characteristics, transformation relationships, critical flow velocities for fluid carrying sand. The experimental...
<title>Abstract</title> Traditional corrosion inhibitors are constrained in their sustainable development due to high costs, significant environmental toxicity, poor degradability, and inadequate dispersibility. Although environmentally friendly carbon dot-based hold potential as alternatives, precise controllable synthesis, well high-yield production, remain challenging existing technical bottlenecks. This study employs a "synthesis-modification" stepwise approach. Initially, basic...
Addition of melamine formaldehyde (MF) as a crosslinker containing hydroxymethyl to partially hydrolyzed poly(acrylamide) (HPAM) generated covalently crosslinked in situ gels through chemically nucleophilic attack by groups amide an HPAM backbone, which was demonstrated FTIR spectrum analysis and rheological studies. NH4Cl could act catalyst reduce the gelation time from 7 days dilute water 8 h presence 0.8 wt % NH4Cl. Compared high-temperature HPAM/phenol/formaldehyde HPAM/Cr3+ gel systems,...
Conventional preformed particle gels suffer from insufficient salt tolerance and weak mechanical properties after water absorption, which reduce the shutoff effect in mature oilfields. In this paper, a nanocomposite gel (NCPG) is synthesized by copolymerization of acrylamide (AM) 2-acrylamido-2-methylpropane sulfonic acid (AMPS) using laponite RD (LPT) as physical cross-linker N,N-methylene-bisacrylamide (MBA) chemical via situ free radical polymerization. Compared with NCPG without LPT,...
The calculations of friction pressure drop is the most complicated in multiphase flow. Understanding pipes are great importance for many industry problems. existing models generally based on low gas and liquid velocities horizontal vertical pipes. In this paper, a two-phase flow experiment inclined pipe was performed. We report effect superficial drop, results indicate that increases with increase velocity velocity. According to experimental analysis assuming fluid contact wall at high...
To improve the understanding of relationship between silica source and organic matter accumulation, origin its implications for enrichment in Upper Ordovician-Lower Silurian (O3w-S1l) black shale western Hubei Province middle Yangtze area, were investigated through geochemical petrological analyses. The results show that O3w-S1l is mainly composed five lithofacies with varying graptolite abundance, total carbon (TOC), contents. Biogenic terrigenous siliciclastic input constitute main sources...
Based on the mechanistic model of two-phase swirling annular flow behavior, a calculation method for effective distance vortex tool is obtained by taking Kelvin–Helmholtz instability into account. The rationality proposed validated comparing predicted liquid film thickness and pressure under non-swirling with commonly used correlations. Then, influences gas–liquid ratio, helix angle, hub diameter thickness, drop, have been analyzed. Results show that presence causes decrease in increase...
The gelation process of organically polymer gel was investigated by dynamic thickening measurements. Rheological measurements were used to evaluate the viscosity gel. During process, high temperature resulted in higher rate crosslinking. Rigid and stable formed neutral alkaline media, pH value, faster process. However, could not be acid condition. Moreover, crosslinking increased with increase concentration crosslinker. addition NH4Cl elongated time significantly, but played a negative role...
In this study, a self-degrading hydrogel was formed by free-radical-initiated copolymerization, which can be used for oil and gas well strip pressure operations. Fourier transform infrared spectroscopy (FTIR), nuclear magnetic resonance (1H NMR), scanning electron microscopy (SEM), thermogravimetry–mass spectrometry (TGA-MS) were to study the reaction mechanism as microstructure of gels. Then, effects four factors their interactions on gel degradation time determined central composite design...
With the progression of many shale gas wells in Sichuan-Chongqing region China into middle and late stages exploitation, problem sand production these is a primary factor influencing production. Failure to implement measures remove from will lead sharp decline after certain period exploitation. Moreover, As amount produced well increases, layer be potentially buried by sand. To boost improve efficiency, novel downhole jet sand-washing device has been developed. Upon analyzing device's...
