“注好水、注够水”是水驱稳产的基础,近年来,实施大量增注措施,平欠水量得到一定控制,但由于受油层污染、层间干扰等因素影响,喇嘛甸油田水驱平欠水量依然较大。本文通过分析注水井平欠因素,确定欠注原因,通过不同措施治理平欠层,通时防止了周期平欠现象发生。 In recent years, the implementation of a large number of incremental injection measures, the amount of water owed to some control, but due to reservoir contamination, inter-layer interference and other factors, Lamadian Oilfield Water flooding owed less water is still large. In this paper, by analyzing the factors that affect the horizontal well of water injection well, the reason of under-injection is determined, and the leveling is controlled by different measures.
