摘　　要：分析苏皖油田金湖—来安凹陷地层 ,一些井在实施改性钻井液的屏蔽暂堵保护油气层的不科学、不合理的基础上 ,有针对性地指出在设计和施工中认识观点的 9个误区。基于该区域油气储层岩石孔喉特征 ,结合该技术原理和技术要点 ,提出了技术准备。In Jinhu Laian depressed formation of Suwan Oilfield,some wells are executed temporary blocking reservoir protection technique of modified drilling fluid.Through analysis,it is unreasonable and unscientific.In this paper,nine misconceptions of recognition are proposed in design and construction.On the basis of rock pore feature of oil and gas reservoir in Suwan Oilfield and combination the technical principle and main point,technical design and main point of executing the technique are proposed.
