摘要
原油中的有机氯主要来源于油田开发过程中使用的各种油田化学药剂,原油中有机氯含量升高,对原油品质和后续加工的影响极大。按照Q/SHCG 39—2012《油田化学剂中有机氯含量测量方法》,对采油药剂中有机氯含量进行测定。同时,选取四个典型区块,按照GB 18612—2011《原油有机氯含量的测定方法》,实验室模拟现场加药情况,考察了单种不同类型药剂及多种药剂共同作用时对原油有机氯含量的影响。结果显示,采油助剂的有机氯含量对原油的有机氯含量影响明显,特别是油溶性采油助剂,大部分有机氯可转移至原油中,使原油中的有机氯含量增加,导致后续加工工序复杂。因此,要彻底避免原油开采过程中混入有机氯,必须限制或限量使用各类含有有机氯的油田化学助剂,尤其是含有有机氯的油溶性采油助剂。目前,胜利油田根据药剂使用以及与原油接触情况,基本消除了原油处理以及水处理等化学药剂中的有机氯含量。
The organic chloride in the crude oil mainly comes from various oilfield chemicals used during oilfield development.The increase of organic chloride content in the crude oil has a great impact on the quality and subsequent processing of the crude oil.The content of organic chloride in the oil producing additives is determined according to Q/SHCG 39—2012 The Measuration of Organochlorine Content in Oil Field Chemicals.At the same time,four typical blocks are selected,and the additives used in the field production are simulated and then the effects of different kinds of additives individual and combination on the content of the organic chloride in the crude oil are researched according to GB/T 18612 —2011 Determination of Organic Chloride Content in Crude Oil.The research results show that the content of organic chloride in the oil producing additives have a great effect on the organic chloride in the crude oil,especially in the oil soluble oil producing additives,most of the organic chloride can be transferred to the crude oil and make the increase of the content of organic chloride in the crude oil,which results in the subsequent processing more complex.Therefore,the oil additives,especially oil soluble additives with organic chloride must be used limitedly to avoid the organic chloride mixed into the crude oil in the exploitation completely.At present,Shengli oilfield has removed the organic chloride from the oil treatment chemicals and other water treatment chemicals according to the situation of oil additives application and their contact with the crude oil.
