“…The water loss of water-based drilling fluids is crucial to the hydration of boreholes and can cause serious engineering problems (e.g., fracture development, formation leakage, and borehole collapse) [49,50]. Therefore, drilling technologists and engineers created a thin film (which is also called a mud cake) on the surface of each borehole, using the difference in the drilling pressure to reduce the water loss of the water-based drilling fluid.…”

As an important industrial material, bentonite has been widely applied in water-based drilling fluids to create mud cakes to protect boreholes. However, the common mud cake is porous, and it is difficult to reduce the filtration of a drilling fluid at high temperature. Therefore, this paper endowed bentonite with a thermo response via the insertion of N-isopropylacrylamide (NIPAM) monomers. The interaction between NIPAM monomers and bentonite was investigated via Fourier infrared spectroscopy (FTIR), isothermal adsorption, and X-ray diffraction (XRD) at various temperatures. The results demonstrate that chemical adsorption is involved in the adsorption process of NIPAM monomers on bentonite, and the adsorption of NIPAM monomers accords with the D–R model. With increasing temperature, more adsorption water was squeezed out of the composite when the temperature of the composite exceeded 70 °C. Based on the composite of NIPAM and bentonite, a mud cake was prepared using low-viscosity polyanionic cellulose (Lv-PAC) and initiator potassium peroxydisulfate (KPS). The change in the plugging of the mud cake was investigated via environmental scanning electron microscopy (ESEM), contact angle testing, filtration experiments, and linear expansion of the shale at various temperatures. In the plugging of the mud cake, a self-recovery behavior was observed with increasing temperature, and resistance was observed at 110 °C. The rheology of the drilling fluid was stable in the alterative temperature zone (70–110 °C). Based on the high resistance of the basic drilling fluid, a high-density drilling fluid (ρ = 2.0 g/cm3) was prepared with weighting materials with the objective of drilling high-temperature formations. By using a high-density drilling fluid, the hydration expansion of shale was reduced by half at 110 °C in comparison with common bentonite drilling fluid. In addition, the rheology of the high-density drilling fluid tended to be stable, and a self-recovery behavior was observed.

“…The change rule occurs at performance evaluation experiments of nearly all filtrate reducers. 4,9,13,14,[18][19][20] In our experiments, the FL API30min of 36.4 ml in fresh-water base fluid is realized by building the "house of cards" micromechanism of edge-to-face and edge-to-edge attractions among exfoliated clay particles. 7,33 The addition of various chloride salts can increase the anti-pollution and clay-swelling inhibitive capacities of the drilling fluids when encountering salt beds underground.…”

“…For example, adsorption groups of vinyl copolymers are normally nonionic acylamino and ammonium cation, and they are derived from the monomers of acrylamide (AM), N-vinyl pyrrolidone (NVP), dimethyl diallyl ammonium chloride (DMDAAC), and so on, while hydration groups which mainly include anionic COO À and SO 3 À are supplied by the monomers such as itaconate, acrylic acid (AA), 2-acrylamide-2-methyl propane sulfonic acid (AMPS), styrene sulfonate, and so on. [13][14][15][16][17][18][19][20] Recently, research hotspots have been focused on how to synthesize filtrate reducers with unique molecular structure (appropriate copolymerization ratio, functional group distribution along the polymer backbone and magnitude and distribution of molecular weight), aiming to the sustainable optimization of filtration properties of drilling fluids. It is beyond doubt that the preparation of novel filtrate reducers is becoming more and more difficult due to the lack of raw material source and the bottleneck of polymerization and modification technology development.…”

The water-bentonite drilling fluids incorporating the terpolymer of acrylic acid, acrylamide, and 2-acrylamide-2-methyl propane sulfonic acid were prepared by common mechanical agitation of industrial community with superposition of ultrasound. Various performances of the drilling fluids in the absence and presence of ultrasonic oscillations were evaluated, including fluid loss, rheology, mud cake thickness, and surface appearance, adsorptive capacity of terpolymer on bentonite clay as well as clay particle size and distribution. The results showed that the filtrate volume and mud cake thickness as well as rheological values presented downtrend with the increase of ultrasonic time or power. Scanning electron microscope showed that the more smooth-faced and compact mud cake was formed after ultrasonic oscillations. The analysis of clay particle size confirmed that ultrasonic oscillations could reduce the average particle diameter and broaden the particle size distribution, along with the appearance of ultra-tiny clay particle components. Adsorbed amount of terpolymer on bentonite was enhanced with introduction of ultrasonic oscillations (as confirmed by total organic carbon analysis). The ultrasound-induced dispersion and adsorption stemmed from acoustic cavitation and could cooperate with each other, together improving filtration properties.

“…(2) Cationic monomer DMDAAC was used to enhance the attraction force between PNS and shale matrix through electrostatic interaction. (3) It has been well-studied that the use of the monomers of the ST and AMPS could increase the thermal stability of polymeric drilling fluid additives (Wu et al, 2001;Huo et al, 2018;Mohamadian et al, 2019) because the rigid side-chain of ST and hydrolysis resistant group (-SO 3 H) of AMPS are beneficial to temperature resistant property of polymeric additives. (4) In order to further improve the thermal stability of PNS in WBM, the cross-linking agent MBA and the silane coupling agent KH550 were used to form double cross-linked structure to decrease the mobility of polymer chains.…”

Nanoscale plugging agent is essential to wellbore stability of troublesome shale formation in the drilling of oil and gas wells. In this paper, polymeric nanospheres (PNS) with a double cross-linked structure were synthesized using monomers of styrene (ST), acrylamide (AM), 2-Acrylamide-2-methylpropanesulfonic acid (AMPS), and dimethyl diallyl ammonium chloride (DMDAAC). PNS were characterized by FTIR, SEM and TGA. The plugging performance of PNS was analyzed using nitrogen adsorption experiments and SEM. And compatibility with water based drilling fluid (WBM) was studied. Experimental results showed that PNS had a mean particle size of 133 nm, and could retain about half of the original size after high temperature treatment under 150-200 • C. TGA showed that the initial decomposition temperature of PNS is around 315 • C. After plugging by PNS, both the specific surface area and pore volume of the shale cuttings decreased substantially compared with those of shale samples treated with water. Thus, PNS was thermal stable in WBM under high temperature and could effectively plug shale pores. Besides, PNS was beneficial to reduce both API and HTHP fluid loss of WBM.
