| Abstract: | The low permeable reservoir in Xingshugang oilfield have some problems such as high clay mineral content,serious reservoir damage and poor water absorption capability of water injection wells. Based on the sensitivity study on the low permeable reservoirs in the oilfield, this paper studies the matching technique of reservoir protection and acidizing. Laboratory experiment and pilot test show that this technique can effectively increase the water absorption thickness of water injection wells and improve the water absorption capability of the reservoirs. It can be operated with a long effective term. |
