一种耐酸耐碱高强树脂的合成及性能
Synthesis and performance test of an acid and alkali resistant high strength resin
摘要
Abstract
Secondary cementing of small casing is a new type of cementing technology.At present,due to the brittleness of cement itself,it is easy to gas channeling and water channeling,and it is an alkaline solidified body,which is easy to produce cracks under pressure,and it is also easy to be damaged by acidic medium.An unsaturated polyester resin was synthesized by using D-33 diol and maleic acid as raw materials and styrene as dispersant.The introduction of fillers in the resin system improved the toughness and compressive strength of the product.The resin was characterized by FTIR.The performance of the resin system was evaluated by universal testing machine.The results indicated that the target product contained the characteristic peaks of aldehyde group,carbon-carbon double bond and p-benzene ring structure.The curing system was dibenzoyl peroxide/N,N-dimethylaniline,and its dosage at 50℃,60℃ and 70℃ was 0.2％/0.02％,0.1％/0.02％and 0.1％/0.01％,respectively.The test results of universal testing machine showed that the compressive strength after curing at 50℃,60℃ and 70℃ for 24h was about 50MPa,70MPa and 90MPa,respectively.A cementing material with adjustable polymerization time,low viscosity,high pressure resistance,acid and alkali resistance was obtained in the experiment,which was expected to be widely used in horizontal well refracturing.关键词
