摘要
Abstract
The water injection of some oil wells in Zhenbei oilfield and Huaqing oilfield is not enough due to reservoir property and water injection mode. According to the analysis of reservoir property and present water injection state,it is held that the acidization of the superlow-permeability reservoirs is needed. The acidizing liquid system was developed by laboratory experiments, and the acidizing technology is optimized. It was injected into core and can make the permeability of the core increased 30% . It can remove the damage of water injection to cores,and makes the permeability of the cores recovered. The field acidizing tests of 15 wells show that the effectiveness ratio of the acidizing construction is 93. 3% ,and that water injection pressure declines 2. 9 MPa and single-well water injection increases by 15 m /d on average.关键词
