摘　　要：川东地区发育多套储层,既有典型的致密砂岩和碳酸盐岩储层,也有异常发育的孔隙型储层。裂缝不同程度地发育,垂直裂缝、高角度裂缝常见。碳酸盐岩储层粘土矿物以伊利石为主,具有明显的水敏性、速敏性、盐敏、碱敏性和酸敏性。基块的应力敏感性属弱—中等,裂缝岩样属中—强。固相侵入、水相圈闭损害是产能损失的主要原因。研制屏蔽暂堵钻井完井液配方,保护储层屏蔽暂堵技术在现场应用,取得了预期效果。There are many reservoirs in East Sichuan area, consists of not only the close sand and the carbonate formation, but also the pore morphology reservoir of structural abnormality The fractures with structural abnormality, vertical and high angle are common. The illite is the key sial lite in carbonate formation, and the carbonate formation has the feature of water sensitivity, rapid sensitivity, salt sensi tivity and acid sensitivity. The stress sensitive of the block is weak?moderation, and the rock sample is moderation ?powerful. The invasion in solid phase and trap damage in water phase are main reasons of productivity impairment. The expected value on Research the dispensation of screen bridg ing in drilling and completion fluid and application of the reservoir protection and screen bridging technology on sitefield is good
