During ultradeep oil and gas drilling, fluid loss reducers are highly important for water-based drilling fluids, while preparing high temperature- salt-resistance with excellent rheology filtration performance remains a challenge. Herein, micro-crosslinked amphoteric hydrophobic association copolymer (i.e., DADC) was synthesized using N,N-dimethyl acrylamide, diallyl dimethyl ammonium chloride, 2-acrylamido-2-methylpropane sulfonic acid, monomer, pentaerythritol triallyl ether crosslinker....
Shale hydration is the main reason causing wellbore instability in oil and gas drilling operations. In this study, nanoscale laponite as a shale inhibitor was employed to stabilize wellbores. The inhibition property of suspensions evaluated by an immersion experiment, linear swelling measurement, recovery test. Then mechanism studied using capillary suction time (CST) thixotropy plugging performance evaluation, related theoretical analysis. Evaluation experiment results showed that had...
Abstract High-performance water-based drilling fluids (HPWBFs) are essential to wellbore stability in shale gas exploration and development. Laponite is a synthetic hectorite clay composed of disk-shaped nanoparticles. This paper analyzed the application potential laponite HPWBFs by evaluating its inhibition, plugging lubrication performances. Shale inhibition performance was studied linear swelling test recovery test. Plugging nitrogen adsorption experiment scanning electron microscope...
Summary The rapidly increasing global oil/gas demand and gradual depletion of shallow reservoirs require the development deep geothermal reservoirs. However, drilling suffers from drilling-fluid failures under ultrahigh temperature, which cause serious accidents such as wellbore collapse, stuck pipe, even blowouts. In this study, we revealed role polymeric additives in improving ultrahigh-temperature tolerance bentonite-based fluids, aiming to provide practical efficient solutions failure...
With increasing global energy consumption, oil/gas drilling has gradually expanded from conventional shallow reservoirs to deep and ultra-deep reservoirs. However, the harsh geological features including high temperature salinity in have become a critical challenge faced by water-based fluids (WDFs), which seriously deteriorate rheology fluid loss properties, causing accidents, such as wellbore instability formation collapse. In this study, novel temperature- salt-resistant micro-crosslinked...
The ever-mounting drilling operations in the petroleum industry have been accompanied by a tremendous amount of wasted fluid, polycyclic aromatic hydrocarbons (PAHs), which poses huge threat to human health and ecosystem. In this study, novel oxygen-rich defective photocatalyst with multiheterostructure was fabricated two-step deposition, exhibits impressive photocatalytic activity toward naphthalene pyrene under full-spectrum irradiation. Fourier transform infrared spectroscopy, Raman...
Exploitation and utilization of urban underground space resources is gaining increasing attention in cities’ sustainable development. Due to the attributes fragility irreversibility, can be extremely vulnerable damage it often difficult restoring their original state once damaged. Therefore, scientific reasonable evaluation vital importance planning This paper first describes content methods for resources, introduces digitalization technologies handle problems strong subjectivity, low...
Nanoscale plugging agent is essential to wellbore stability of troublesome shale formation in the drilling oil and gas wells. In this paper, polymeric nanospheres (PNS) with a double cross-linked structure were synthesized using monomers styrene (ST), acrylamide (AM), 2-Acrylamide- 2-methylpropanesulfonic acid (AMPS) dimethyl diallyl ammonium chloride (DMDAAC). PNS characterized by FTIR, SEM TGA. The performance was analyzed nitrogen adsorption experiments SEM. And compatibility water based...
Drilling fluids face failure during drilling deep reservoir with high temperature and salt. The experimental results show that salinity reduce the negative charge on surface of bentonite in fluid cause coalescence particles. As a result, particles coalesce, grid structure is destroyed, rheological properties, rock-carrying capacity filtration properties are lost. To resolve foregoing, this study, 0.05-wt% carbon nanotubes introduced into 4% under conditions where concentration added NaCl...
