Analysis of contaminants in water produced from formation with polymer flooding and the mechanism of their damage to formation;
系统分析了大庆南三区东部聚合物驱产出水处理前后各组分的含量及分布 ;根据油层损害机理及该区油层的孔渗特征 ,研究和确定了污染物质和污染机理 ;认为聚合物驱产出水中硫酸盐还原菌是主要污染物质 ,向萨尔图、葡萄花油层的低、中渗层及高台子油层回注时 ,固体悬浮物和原油也是主要污染物质 ,而聚合物仅对低渗层造成损害 ;固体颗粒在孔喉中形成“桥塞” ,为油珠进一步堵塞孔喉提供了条件 ,渗透率的降低远比只含有固相颗粒或油珠的流体严重 ;硫酸盐还原菌因大量繁殖聚积而产生沉淀 ;高分子聚合物主要是以吸附方式堵塞低渗透地
