摘　　要：通过室内实验对坨 12 8区块的储层损害因素进行分析研究 ,优选出保护油层MMH钻井液和油溶性暂堵剂的类型 ,制定了钻井施工中的油层保护方案 ,在该区块三口井实施后 ,与未采用油层保护井对比 ,增油效果明显 。Based on lab experiments,the factors causing reservoir damage in Tuo 128 Tract were analyzed and studied the types of MMH drilling fluids and oil-soluble temporary plugging agents for minimizing reservoir damage were optimized and a plan for controlling reservoir damage was also worked out.By performing the plan in 3 wells in the tract and comparing them with other wells,oil production was obviously increased.This study has better directive significance for the work of reservoir damage control to be carried out in the future.
