一种疏水缔合聚合物稠化剂的合成及压裂液性能评价
Synthesis of a hydrophobically associating polymer thickening agent and evaluation of the f racturing fluid properties
摘要
Abstract
A hydrophobically associating polymer thickening agent HAPAM‐18 for fracturing fluid was synthesized by the aqueous solution free‐radical copolymerization of AM ,AMPS and a cationic hydrophobic monomer MD‐18 .The thickening ability and interactions with surfactant of HMPAM‐18 were studied as well as the fracturing fluid properties .Result shows that the apparent viscosity of HAMPAM‐18 solution increased with increasing concentration and its critical aggregation concentra‐tion is 0 .15 g/L .The interactions between HAPAM‐18 and surfactants fitted the three stage model and the interactions between HAPAM‐18 and SDBS is more intensive than that with CTAB .The frac‐turing fluid system composed of 0 .6 g/L HAPAM‐18 + 0 .5 mmol/L SDBS + 2 g/L KCl reached a temperature resistance of 101 ℃ and showed good shear resistance and viscoelasticity .The fracturing fluid system can be completely broken with unmeasurable insoluble residuals by ammonium persulfate as the gel‐breaker w hich means this system can be taken as clean fracturing fluid .关键词
