“…It is considered one of the crucial parameters that leads to completing a well in an efficient way. [3][4][5] With the increase in downhole temperature, the conventional mud additives including biopolymers and cellulose derivatives degrade, resulting in the deterioration of mud properties. 6,7 In order to address these identied limitations, investigations are currently in progress aimed at identifying substitute materials in lieu of the conventional mud additives.…”

“…9: 220385 reducers could improve their high temperature and salt resistances [29][30][31][32]. Wang et al [33] prepared a nanocellulose filtrate reducer that reduced the filtration of 25.0 wt% brine-based mud to 18.6 ml after hot rolling at 180°C with the dosage of 2.0 wt%. Its performance was better than that of sulfonated lignite (SMC).…”

In drilling deep complex formations, most drilling fluid additives have insufficient temperature and salt tolerance, resulting in the decline of drilling fluid performance. This study used 2-acrylamide-2-methylpropane sulfonic acid, acrylamide, dimethyl diallyl ammonium chloride and modified nano-laponite to synthesize a nanocomposite filtrate reducer (ANDP) with excellent temperature and salt resistance, which can maintain the performance of drilling fluid. The structure of ANDP was analysed by a transmission electron microscope and an infrared spectrometer. The thermal stability of ANDP was studied by thermogravimetric analysis. The performance of ANDP was evaluated in a water-based drilling fluid. The mechanism was analysed per clay particle size distribution, Zeta potential, filter cake permeability and scanning electron microscopy imaging. The results show that ANDP has good thermal stability and the expected molecular structure. The filtration of freshwater drilling fluid after ageing at 200°C is 10.4 ml and that of saturated brine drilling fluid is 6.4 ml after ageing at 150°C. Mechanism analysis suggests that the ANDP increases the thickness of clay particle hydration layer and maintains the colloidal stability of the drilling fluid. ANDP inhibits the agglomeration of clay particles and significantly reduces the filtration by forming dense mud cake.

Synthesis and properties of a high-performance environment-friendly micro–nano filtration reducer

Abstract: In this research study, we modified hydroxyethyl cellulose to obtain hydrophobically associating hydroxyethyl cellulose, and grafted it onto the surface of nano-calcium carbonate to obtain a graft copolymer.
