Abstract

本发明涉及一种抑制稠油中沥青聚集析出和吸附功能的沥青抑制剂及其制备方法。首先制备了2,2‑双(4‑羟苯基)丙烷‑乙烯基苯共聚物，然后其苯羟基上接枝了环氧氯丙烷；然后将其与乙烯基吡啶与乙烯吡咯烷酮共聚物进行接枝交联，生成一种对原油沥青具有较强亲和力的大分子。该大分子通过∏‑∏相互作用与稠油中的沥青分子产生分子间结合，阻止沥青分子之间以及沥青分子与胶质分子间的聚集，防止沥青分子在油层岩石界面以及输油管线内的吸附，进而降低稠油的流动阻力，提高稠油的采收率和输送效率。制备方法科学合理，工艺简单，成本低廉，提供了一种制备沥青稳定剂的新途径。

Description

一种高效沥青聚集抑制剂及其制备方法
技术领域
本发明属油田化学助剂领域，特别是涉及一种稠油开采、输送用助剂及其制备方法。
背景技术
目前的技术和成本因素使得石油开采行业面临着巨大的压力和挑战，尤其是稠油油藏。伴随着稠油开采量的不断增加，高密、高粘、流动性差的特性给稠油开采和输送带来了极大困难，大大增加了生产成本。稠油开发、输送的关键在于防止稠油中的沥青在油层和输油管道中聚集吸附，特别是防止沥青在油层内的聚集吸附。
本发明研制了一种具有高效抑制沥青聚集析出和吸附功能的沥青抑制剂，该抑制剂能够与稠油中沥青分子产生稳定的结合，阻止了沥青分子之间以及沥青分子与胶质分子间的进一步聚集，同时阻止了沥青分子在油层岩石界面以及输油管线内的吸附。进而降低了稠油的流动阻力，提高稠油的采收率和输送效率。
发明内容
本发明涉及一种抑制稠油中沥青聚集析出和吸附功能的沥青抑制剂及其制备方法。利用环氧氯丙烷作为交联剂，将乙烯基吡啶与乙烯吡咯烷酮共聚物与2,2-双(4-羟苯基)丙烷-乙烯基苯共聚物连接，生成一种对原油沥青具有较强亲和力的大分子。该大分子通过∏-∏相互作用与稠油中的沥青分子产生分子间结合，阻止沥青分子之间以及沥青分子与胶质分子间的聚集，防止沥青分子在油层岩石界面以及输油管线内的吸附，进而降低稠油的流动阻力，提高稠油的采收率和输送效率。
下面通过具体实例进一步说明本发明。
具体实施方式
实施例1
(1)将0.05mol2,2-双(4-羟苯基)丙烷加入三口反应瓶中，通N2，驱尽空气，升温至160℃融化后，缓慢加入1克98％浓硫酸，搅拌均匀，搅拌下缓慢滴加0.3mol苯乙烯，控制滴加速度，使反应温度保持在170～175℃，滴完后继续保温2h，降温至25℃，得无色透明粘稠液体，上述产物加100ml无水乙醇稀释溶解，再加入2克氢氧化钾和0.05mol环氧氯丙烷，升温至35～40℃，强力搅拌3h，冷却，备用；
(2)将0.05mol4-乙烯基吡啶和0.01mol乙烯吡咯烷酮置入反应瓶中，加入50g乙醇和水的混合溶液中，其中乙醇：水＝1:3，然后再加入0.05g过氧化苯甲酸，搅拌溶解均匀，通N2，驱尽空气，升温至70℃，在70-75℃温度下反应5h，生成浅黄色粘稠透明液体，冷却至25℃，备用；
(3)将步骤一的生成物加入步骤二生成物中，充分搅拌均匀成一相，加热至65～70℃，搅拌反应3h，降温，得深红色粘稠液体。
实施例2
(1)将不同量的沥青溶解于甲苯中，配置出不同浓度沥青质的甲苯溶液。25℃下用UV7501型紫外分光光度计在350nm波长下测定不同浓度沥青质甲苯溶液的吸光度，见表1。绘制吸光度-沥青质浓度标准曲线。曲线为一过坐标原点、斜率为0.405的直线，方程式为：Y＝0.405X，式中X为甲苯溶液中沥青质浓度(mg/L)，Y为沥青质甲苯溶液的吸光度(％)。
表1不同浓度沥青质甲苯溶液的吸光度(25℃)
沥青质浓度，mg/L 0 30 50 70 100 120 150 200
溶液吸光度，％ 0 12.14 20.26 28.36 40.48 48.58 60.77 80.98
(2)按(1)中同样的方法，25℃下，配置出浓度分别为50mg/L、100mg/L和150mg/L的三种沥青质甲苯溶液；每种浓度的溶液均按以下浓度加入实施例1中的产物：0、1、3、5、7、10mg/L，充分振荡使溶液均匀；然后往各种溶液中加入等体积的正庚烷，振荡1小时，静止24小时；取上层清夜用0.45um微孔滤膜过滤，在350nm波长下测定不同药剂加量下滤液的吸光度，用方程式Y＝0.405X计算不同药剂加量甲苯溶液的沥青质浓度。按下列公式计算药剂的沥青质抑制率：抑制率＝[(X0-X)/X0]×100％，式中X0和X分别为空白(加药量为0)和加入药剂的甲苯溶液的沥青质浓度。结果见表2。三种溶液药剂加量大于7mg/L时沥青质抑制率均超过了90％。
表2不同药剂加量下的沥青质抑制率(25℃)
实施例3
25℃下，将不同量的沥青溶解于甲苯中配置出浓度为150mg/L的沥青质甲苯溶液；分别按以下浓度加入实施例1中的产物：0、1、3、5、7、10mg/L，充分振荡使溶液均匀。然后每25ml上述溶液中分别加入10克粒径为0.1～0.3mm的天然岩心颗粒，密封、静止浸泡7天。取上层清夜用0.45um微孔滤膜过滤，在350nm波长下测定滤液的吸光度。用方程式Y＝0.405X计算甲苯溶液的沥青质浓度。按下列公式计算不同加量药剂作用下天然岩心对沥青质的吸附量和吸附率：吸附量＝(150-X)×0.025，式中X为处理后甲苯溶液的沥青质浓度，吸附率＝吸附量/(150×0.025)，结果见表3。浸泡7天后，天然岩心颗粒对未加药甲苯溶液中沥青质的吸附率高达49.3％，而当加药量为7mg/L时，天然岩心颗粒对沥青质的吸附率小于0.5％。

加药量，mg/L 0 1 3 5 7 10
天然岩心吸附量，mg 1.85 0.18 0.10 0.06 0.01 0
沥青质吸附率，％ 49.3 4.8 2.7 1.6 0.3 0
实施例4
按照实施例3，将10克天然岩心颗粒更换为一A3钢片(规格：76mm×13mm×1.5mm)，密封、静止浸泡30天。同样的方法测定并计算A3钢片对甲苯中沥青质的吸附率。结果见表4。浸泡30天后，A3钢片对未加药甲苯溶液中沥青质的吸附率高达27.7％，而当加药量为5mg/L时，A3钢片对沥青质的吸附率小于0.5％。
