摘　　要：以吐哈油田LSl井为实例,介绍了低渗透裂缝性泥砂岩储层的试油技术。由于本井储层特殊,试油中难点较多,具体施工中,针对储层渗透性差、微裂缝发育、泥质含量高的不利因素,制定了与之相适应的技术措施,从强化射孔、地层测试、排液求产到酸化压裂改造都采用了较为先进的手段,有效地保护了储层,探索了一条特殊储层试油的新路子。Taking Well LSI of Tuha oil field as an example, this paper presents oil production testing technology for low permeability fractured shaly sandstone reservoir. Many difficulties encountered in the course of oil production testing of the well due to its special reservoir. Aiming at unfavorable factors in practical operation such as: poor reservoir permeability, mature mierofractures, high shale content, we chose proper technique measure, adopted more advanced means of enforced perforation, formation test, flowing back for production, acidizing and fracturing and have explored a new approach of special reservoir oil testing.
