摘要(Abstract)：

结合大庆长垣外围油田低渗透储层的地质特征,对酸化工艺进行了研究。筛选出了OP-7和TDC-10两种较为理想的粘土稳定剂,并通过实验确定了其最佳使用浓度,用岩屑称重法和岩心实验法优选了土酸配方,制定了土酸酸化注入程序。通过现场施工观察,收到了较好的增产、增注效果。
Acidization technology is studied according to the geological characteristics of low permeability reservoirs around Daqing Placanticline. Two kinds of satisfactory stabilizing agents for clays, OP-7 and TDC-10, have been screened, and the optimum concentration has been determined through experiments. Mud acid prescr iption is optimized by using the cutting weighting method and the core test met hod and the program of mud acid injection is made. Through field application, improvements have been gained in oil production and water injection.
