“…Water-based lubricants have been at the vanguard of recent research for a wide range of industrial applications due to the abundance and total eco-friendliness of water [1,2]. The idea of using water-based lubricants emerged from the global industry interest in replacing fossil oil-based lubricants with renewable sources (i.e., water or bio-derived oils).…”

Recent green manufacturing demands have boosted the development of new biodegradable lubricants to replace petroleum-based lubricants. In this regard, water-based lubricants have been at the vanguard of recent research for a wide range of industrial applications, including metalworking fluids (MWFs). In this work, we present an experimental investigation on the performance of novel green MWFs based on aqueous nopal mucilage solutions. For this, fully biodegradable solutions with different mucilage concentrations (2.29, 4.58, and 6.85 mg/mL) were evaluated in terms of rheological, tribological, thermal stability, and turning (minimum quantity lubrication) performance and compared to a commercial semisynthetic oil-based MWF (Cimstar 60). Mucilage solutions exhibited viscoelastic shear-thinning behavior, which was enhanced along with mucilage concentration. The solution with the highest mucilage content studied resulted in the lowest wear, friction, and temperature in comparison to the other solutions and neat water in extreme pressure four-ball tests and a similar level of lubricity as compared to the commercial MWF in cutting tests. This performance is associated with the enhanced viscosity and elasticity of the solution, as well as the contents of lipids with fatty acids in the mucilage. Overall, the present results reveal the relevance of the viscoelastic behavior of the lubricant, elasticity in particular, in lubrication processes and point to nopal mucilage as an effective green additive to produce innocuous MWFs.

“…In the initial exploiting stage of the horizontal section, the lubrication effect of the above-mentioned lubricants is obvious, usually making the viscosity coefficient of the mud cake less than 0.2. But in the middle and late stages of drilling, as the in solid-phase content in the drilling fluid increases, the effect of asphalt and oil-based liquid-phase lubricants is not significant, and the wellbore mud cake appears weaker as a result of using excessive oil-based liquid-phase lubricants, which can easily cause stuck drilling. , Meanwhile, traditional liquid lubricants are prone to foam, have poor stability, have fluorescence effects, and even affect the rheology of the drilling fluid, while solid lubricants are generally difficult to degrade and are prone to environmental contamination and reservoir damage, thus limiting their use in horizontal wells. − In addition, when the solid content of drilling fluid is high, adding liquid lubricants thickens the outer oil film of solid particles, reducing the stacking density of solid particles on the wellbore wall, thickening the wellbore mud cake, reducing its strength, increasing the difficulty of flushing, causing serious weak interface phenomena in cementing, and resulting in a decrease in the quality of interface bonding. In order to solve the problem of the poor quality of mud cake leading to weak cementing interface, mud cake removal method and mud cake modification method are mainly developed .…”

In view of the problems in which the solid content of drilling fluid increases in the middle and late stages of horizontal well drilling, the lubricity of mud cakes on the borehole wall decreases, and the friction of pipe string increases due to the gradual thickening of mud cakes, which leads to the sticking and the obvious decrease of cementing strength at the second interface, a mud cake improver Mul-GX with lubrication and interface enhancement effect was studied in this paper. Based on the hydration and filling mechanism, the lubricity of the mud cake was improved, its thickness was reduced, and its strength was improved through synergistic effects of solvated water film lubrication and buffering, hardening and crystallization of gelled substances, and filling and dispersion of elastic particles. The mud cake improver Mul-GX is composed of the metasilicate GX-ZQ, polymer copolymer GX-JB, and polymer GX-TX, and the mass ratio of each component was GX-ZQ: GX-JB: GX-TX = 15:1:0.5. The effect of Mul-GX was evaluated through the performance determination of the mud cake and interface cementing simulation experiments. In addition, the microscopic characterization by SEM and XRD were carried out to analyze the mechanism of Mul-GX. The experimental results showed that when Mul-GX was added to the water-based drilling fluid with the 1.0%−1.5% adding quantity, the mud cake lubricity improved by more than 60%, its thickness reduced by 53.9% on average, and its strength increased by 54.3% on average. At the same adding quantity, the interfacial bonding strength was 4.4 times more than the data before adding Mul-GX. All of the results showed that Mul-GX has obvious mud cake lubrication effect and interface enhancement effect.

The ever‐increasing consumption of fossil energy highlights the urgent need to develop technologies to ensure the efficient drilling and exploration of oil and gas resources mainly distributed in deep and ultra‐deep layers. The complex geological conditions in deep formations with the feature of high temperature, high pressure and high salinity result in some very high requirements for the performance of drilling fluids. Various additives were demonstrated to decide the physicochemical properties and functional characteristics of water‐based drilling fluids that have been widely used to drill over 80% of wells. As one of the most crucial and most widely used additives in water‐based drilling fluids, various polymeric filtrate reducers play an important role in minimizing fluid loss, maintaining wellbore stability, ensuring drilling safety and efficiency as well as avoiding formation damage. Herein we comprehensively summarized the design, preparation and applications of polymer‐based filtrate reducers for fluid loss control in drilling operation. The spotlight is centered on the design strategies and structure‐property‐performance relationships of polymeric filtrate reducers to minimize fluid loss under high temperature, high pressure, and high salinity conditions in the deep formation. Future perspectives for achieving excellent comprehensive performance are also discussed to motivate new strategies and technologies to design and develop high‐performance water‐based drilling fluids with optimal rheological and filtration properties.This article is protected by copyright.
