裂缝孔隙型储层钻井完井保护技术

Formation Protection Technique for drilling and Completion in Fractured Porous Reservoirs in Xiaoguai Oilfield, Xiujiang

文中对小拐油田的储层特征进行了分析，并研究了桥堵规律及处理剂损坏因素，尤其重点研究了单条裂缝岩心桥堵规律，在此基础上探讨了小拐油田现场应用的钻井完井液体系配方．并在配方中引用了一种新研制的多功能油层保护剂J－QD。

This paper analyzes the reservoir features of Xiaoguai oilfield and studies bridging regularities and damaging factors of additives with focus on core bridging regularity of single fracture. On base of these studies, this paper discusses the damaging factors of the drilling and completion fluid systems used in Xiaoguai oilfield and provides a modified formulation of drilling and completion nuid system in which a newly developed multifunctional oil layer protective agent JQD is used.
