摘　　要：针对新疆油田公司百21井区百口泉组砾岩油藏调剖(驱)效果逐年变差、控制产量递减速度难度较大等问题,在分析了油藏存在的主要问题和油藏历年的调剖(驱)措施效果基础上,明确了百21井区百口泉组砾岩油藏对调驱体系要求,即调剖体系应具有较强的抗剪切能力以及建立有效沿程阻力的能力。就常用的非线性聚合物和常规HPAM聚合物,通过分析微观结构以及岩心流动实验,研究了其抗剪切性能和建立残余阻力系数的能力,并提出了适合于砾岩油藏"垫、堵、调、驱相结合"的深部调驱治理思路。According to the problems, such as poor profile control effect, difficult to control the production decline of the conglomerate reservoir in Baikouquan oilfield, 21th well area, combined with the analysis of the main issues existent in the reservoir and the past profile control effect, the requirement of conglomerate reservoir for profile control system was put forward, that is the profile control system should have a strong anti-shear capacity and effective resistance capacity. The shear resistance capability and establishing residual resistance factor capability of the nonlinear polymer and conventional HPAM polymer were studied by analyzing their microscopic structure and core flow tests, and the deep profile control and oil displacement measures suited for conglomerate reservoir were proposed.
