| 摘 要： | 针对裂缝－孔隙型储层特征和钻井施工要求，从储层潜在损害因素分析入手，确定了裂缝暂堵剂，即以超细碳酸钙和改性石棉纤维为主复配而成的纤维状暂堵剂LF－1，以及以油溶性树脂和液体石蜡为主复配而成的油溶性软化封堵剂EP－1，并优选出了钻完井配方。现场试验表明，该钻完井液体系基本满足钻井施工要求，储层保护效果明显，可使表皮系数下降54．4％。

| Abstract: | Based on the fracture pore type reservoir characteristics and drilling engineering requirements, and starting from the analysis of potential reservoir damage factors, temporary bridging agents are determined for fracture pore type reservoir protection. These are the fibrous temporary bridging agent LF 1 mainly containing superfine calcium carbonate and modified asbestos fiber and the oil soluble soft temporary blocking agent EP 1 basilally composed of oil soluble resin and fluid paraffin wax. The drilling and completion fluid formulations are optimized therefore. The field test indicates that the system basically meets the drilling engineering requirements, and reservoir protection gains obvrious effects, that is to say, the decline of skin factor is 54.4%. |
