抗230℃水基钻井液用悬浮剂的研制与性能
Development and Performance of a Water-Based Drilling Fluid Suspending Agent Resistant to 230℃
摘要
Abstract
In high-temperature and ultra-high-temperature drilling operations,the decrease in drilling fluid gel strengths causes the settling stability and the sand carrying capacity of the drilling fluid to reduce,which results in uneven dispersion of the solid particles and cuttings agglomeration in the drilling fluid.To address this problem,a quaternary polymer drilling fluid suspending agent,XFJ-3#,which exhibits temperature resistance up to 230℃,was designed and synthesized using AMPS(2-acrylamido-2-methylpropanesulfonic acid),SAS(sodium allylsulfonate),SSS(sodium p-styrenesulfonate)and MBA(methylene bisacrylamide)as the main raw materials.Fourier transform infrared spectroscopy(FT-IR),thermogravimetric analysis(TGA)and 1H nuclear magnetic resonance spectroscopy(1H-NMR)were used to characterize XFJ-3#.The results show that XFJ-3#is the target product.XFJ-3#loses only 60%of its weight at 600℃.Performance evaluation results show that a 5%Bohai drilling clay slurry treated with 1%XFJ-3#retains more than 70%of its gel strengths after aging at 230℃for 10 days.The suspending agent XFJ-3#can effectively improve the ability of a drilling fluid to maintain its settling stability for a long time under ultra-high temperature environments.关键词
