摘　　要：文章以储层微观机理研究为切入点,从粘土矿物成分、微粒粒径分布、速敏等方面,研究了苏里格气田是否存在着微粒运移可能性、微粒运移引起孔喉堵塞程度。并提出了预防微粒运移技术对策,重点对粘土稳定剂的防膨长效性评价方法进行了探讨性的试验研究。为进一步完善苏里格气田压裂液体系的性能,确定压裂后排液及合理的生产参数提供理论依据。With the study of reservoir microscopic mechanism, according to the components of clay mineral, the distribution of fine-grain size, and the rate sensitivity etc., the possibility of fine-grain migration is studied and the pore-throat plugging level caused by fine-grain migration is investigated for Sulige gas field. The countermeasures are proposed to prevent fine-grain migration. The experimental study is conducted emphatically for the evaluation method of anti-swelling durability of clay stabilizer. The article provides the theoretical basis for Sulige gas field to improve the performance of fracturing fluid system and determine the flowing back and the reasonable production parameters after fracturing.
