三元复合驱硅垢防垢剂SY-KD的合成及应用
Synthesis and Application of Silicon Scale Inhibitor SY-KD Under the ASP Flooding System
摘要
Abstract
By analyzing silica scale formation mechanism under the alkaline/surfactant/polymer( ASP) floo-ding system, we designed and synthesized a new type of scale inhibitor SY-KD. SY-KD inhibitor is a complex mixture that made by the polymer( CAABS) which is copolymerized by acrylic acid( AA) and p-methyl allyl oxybenzene sulfonate(MBS) &2-phosphate-1,2,4-tricarboxylic acid(PBTC). The carboxyl functional groups of SY-KD can link to the orthosilicic acid molecules or its dimer acid through hydrogen bonding interactions, since the molecular chain of SY-KD's steric effect would prevent further polymerization that the orthosilicic acid molecules or its dimer acid form silica dioxide. Laboratory experiments studies have shown that SY-KD is a good inhibitor for ASP flooding, each component of SY-KD can achieve the silicon scale inhibition ability mainly through the polymerization inhibition, the adsorption and dispersion, and the dissolution of insoluble SiO2 . Field tests have shown that SY-KD scale inhibitor delays the average pump detection period of scaled wells from about 50 d to 300 d.关键词
