Title (EN) THICKENED OIL ACTIVATING AGENT AND PREPARATION METHOD AND USE THEREOF
(FR) AGENT D'ACTIVATION DE PÉTROLE ÉPAISSI ET PROCÉDÉ DE PRÉPARATION ET UTILISATION CORRESPONDANTS
(ZH) 一种稠油活化剂及其制备方法与应用
Abstract:
(EN) Disclosed are a thickened oil activating agent and a preparation method and the use thereof. The thickened oil activating agent is a polymer as shown in a structural formula such as formula (I), where x, y, z, m and n are respectively mass fractions of corresponding chain segments in the polymer, m is 0.75 to 0.85, y is 0.20 to 0.24, and x, z and n are all 0.001 to 0.01; and p is a natural number between 2 to 9. The activating polymer provided in the present invention has the effects of increasing aqueous phase viscosity and reducing the crude oil viscosity at the same time, and can be used as both a flooding agent and a viscosity reducer, thus achieving the aim of one substance acting as two agents. The activating polymer can increase the aqueous phase viscosity, has the function of displacement, can emulsify and disperse the crude oil, and increases the flowability of the mixed phase. Moreover, the dispersed crude oil continues to react with non-contacted crude oil. At the same time, the aqueous phase reacts not only with the mixed oil phase, but also with the new oil, one after another, thereby continually activating more crude oil. The activating polymer of the present invention has a low interfacial tension and a certain oil-washing ability.
(FR) La présente invention concerne un agent d'activation de pétrole épaissi et un procédé de préparation et l'utilisation correspondants. L'agent d'activation de pétrole épaissi est un polymère tel que présenté dans une formule développée telle que la formule (I), où x, y, z, m et n représentent respectivement des fractions massiques de segments de chaîne correspondants dans le polymère, m vaut 0,75 à 0,85, y vaut 0,20 à 0,24, et x, z et n valent tous 0,001 à 0,01 ; et p représente un nombre naturel compris entre 2 et 9. Le polymère d'activation selon la présente invention a pour effet d'augmenter la viscosité de la phase aqueuse et de réduire la viscosité de pétrole brut en même temps et peut être utilisé à la fois comme agent d'injection et comme réducteur de viscosité, ce qui permet d'atteindre l'objectif d'une substance agissant en tant que deux agents. Le polymère d'activation peut augmenter la viscosité de phase aqueuse, a la fonction de déplacement, peut émulsionner et disperser le pétrole brut et augmente la fluidité de la phase mixte. De plus, le pétrole brut dispersé continue à réagir avec du pétrole brut non mis en contact. En même temps, la phase aqueuse réagit non seulement avec la phase de pétrole mixte, mais également avec le nouveau pétrole, l'un après l'autre, ce qui permet d'activer en continu davantage de pétrole brut. Le polymère d'activation de la présente invention présente une faible tension interfaciale et une certaine aptitude au lavage de pétrole.
