摘要
针对渤海SZ36-1油田的地质特征,研究筛选了适合海上稠油油田水驱降粘开采的复合降粘体系。该体系具有用量少、成本低、降粘率高、适应性强、稳定性好等优点。岩心流动实验表明:在注入水中加入复合降粘体系,能有效改善水驱效果,采收率在常规水驱的基础上提高近12个百分点,降粘率在95%以上,可达到高效经济水驱降粘开采稠油的目的。
In accordance with the geological characteristics of Bohai SZ36-1 oilfield,a compounded system of viscosity reduction through water flooding has been chosen for offshore heavy oil field.This system is low usage volume,low cost, high viscosity reduction rate,highly adaptable and stable.Core flow test shows that,when adding the compounded system into injection water,the effectiveness of water flooding can be improved,the recovery factor improves almost 12% based on conventional water flooding,and the rate of viscosity reduction is over 95%.This is a highly efficient and economic method of recovering heavy oil by viscosity reduction through water flooding.
