摘要
油气藏在注水过程中会受到不同程度的污染,注水压力也会相应上升。清水压裂技术为解除近井地带污染、降低注水压力、提高注水量提供了一个新的途径。总结了清水压裂技术的机理和选井原则,并根据油田实际生产情况,对4口注水井实施清水压裂措施,成功率达到100%。截至2006年12月累积增加注水量6 500 m3,增注效果明显,显著提高了注水开发效果,为油田下一步注水开发提供了有力的技术支撑。
In the course of waterflood development,the oil and gas reservoir may be contaminated,which can make the waterflood pressure aseend.Waterfrae treatment technique offers a new method for discharging contamination near wells, decreasing waterflood pressure and enhancing injection rate. This paper sums up the waterfrae mechanism and principle for selecting well. According to the actual condition of the oiffield production,waterfraes techniques are applied in 4 wells with a success ratio of 100%. Up to December in 2006, the accumulative increased injection rate has been 6500 m^3, achieving a good injection effect.The field practice shows this technique can improve the development effect and provide an important technical tool for next waterflood development.
