雷公油田极复杂断块内注水试验研究

为实现极复杂断块注水开发，提高采收率，在百色盆地雷公油田极复杂断块内进行了注水试验，并取得了成功。针对雷公油田的水质及水敏导致注水压力高的问题，通过在井口安装精细过滤器提高注入水水质、投转注水前注前缘保护液、酸化等措施提高了水井吸水能力，实现了正常压力下稳定注水。在雷公油田极复杂断块内转注雷4-10井与雷3-6井，周围4口油井均取得了增油效果，证明了极复杂断块内是可以进行注水开发的。

Water Flooding Experiment of Extremely Complex Fault Zones in Leigong Oilfield

In order to put the super complex fault zone into waterflood development and improve the recovery efficiency, an experiment of injection was done in Leigong Oilfield in Baise Basin,and a success was taken. A elaborate filter has been installed at the wellhead, the protective liquid of the leading edge has been poured into the water well before formal water injection, and the acidification has been used in order to solve the problems of the water quality and the property ,which cause the high injection pressure in Leigong Oilfield and improve the water absorbing capacity of the layers,making the steady water flood under normal pressure become reality.After turning Well L4-10 and Well L3-6 into water well in the super complex fault zone of Leigong Oilfield, four wells around them all get the water flooding effects, demonstrating that the waterflood development in the super complex fault zones is advisable.
