Abstract

本发明涉及一种去除原油中复合驱油剂的方法，该方法利用复合驱容易吸附在亲水热表面的特点，采用沙粒做吸附介质加热到合适温度来实施的。其技术方案是：将40‑20目的沙粒油浴加热到80℃‑90℃，取出后立即分散在含复合驱的原油中，机械搅拌5‑10min，最后过滤、水洗去除沙粒表面的复合驱油剂。该发明解决了复合驱得到的原油地面集输时换热器效率下降或失效问题。

Description

一种去除原油中复合驱油剂的方法
技术领域
本发明涉及一种去除原油中复合驱油剂的方法。
背景技术
复合驱油剂是非单一种类的驱油剂，通过复配共同提高采油效率的混合物，目前井场上应用最多的是三元复合驱、二元复合驱还有多元复合驱。不论是二元、三元还是多元复合驱油体系，表面活性剂和聚合物常常被复合使用。随着油井采油时间的增长，油藏渗透率开始逐渐下降，而采出液中水含量明显增高。为了克服上述不利条件，疏水性更强的表面活性剂和聚合物被广泛使用。疏水缔合水溶性聚合物和多疏水链段的表面活性剂得到使用，并取得了优异的效果。但由于强的疏水特性使其易在原油中残留，给地面集输操作带来困难，直接体现在原油中的聚合物和表面活性剂附着在加热器表面，且随着继续加热形成固体膜，导致换热器传热效果变差或者失效。
发明内容
本发明的目的在于：针对复合驱得到的原油地面集输换热器失效问题，特提供一种去除原油中复合驱油剂的方法。
为了达到上述目的，本发明采用以下技术方案：首先将沙粒油浴加热到80℃-90℃，取出后立即分散在含复合驱的原油中，机械搅拌5-10min，最后过滤、水洗沙粒达到去除复合驱的目的。
一种去除原油中复合驱油剂的方法包括以下步骤：
在室温条件下，称取100g含复合驱油剂的原油加入500mL的烧杯中，在搅拌条件下加入40-20目的沙粒10-20g，搅拌混合5-10min。然后将上述含有沙粒的原油进行真空过滤，滤液为去除复合驱油剂的原油，滤饼为表面吸附了复合驱油剂的沙粒。沙粒用水搅拌洗涤，再过滤可循环利用，洗涤液中通过测定黏度和表面张力估算聚合物和表面活性剂含量。
该发明的意义在于解决了含复合驱油剂的原油在地面破乳和集输时导致加热器或管道表面析出，致使换热器效率显著下降或失效问题。
附图说明
图1 是本发明从原油中去除复合驱油剂的流程图。
具体实施方式
下面通过实施例对本发明进一步说明。
实施例1
在室温条件下，称取大庆油田含复合驱油剂原油100g加入500mL的烧杯中，在搅拌条件下加入40-20目的沙粒12g，搅拌混合5min。然后将上述含有沙粒的原油进行真空过滤，滤饼沙粒用水搅拌洗涤、再过滤，洗涤液采用旋转黏度计测得黏度为82mPa.s，采用界面张力仪测得表面张力48.7N.m-1。
实施例2
在室温条件下，称取大港油田含复合驱油剂原油100g加入500mL的烧杯中，在搅拌条件下加入40-20目的沙粒12g，搅拌混合5min。然后将上述含有沙粒的原油进行真空过滤，滤饼沙粒用水搅拌洗涤、再过滤，洗涤液采用旋转黏度计测得黏度为128mPa.s，采用界面张力仪测得表面张力51.1N.m-1。
