某区水平井堵水效果评价

Effect evaluation of water plugging in horizontal wells in the District

随着水平井开发技术的广泛应用,水平井堵水成为了水平井生产中一个非常关键问题。水平井大量出水会使产油量骤减,含水上升,降低采收率。2012年对某区2口水平井实施堵水,含水下降明显,产油率明显提高,效果明显。

With the wide application of horizontal well development technology,horizontal well water shutoff has become a very important problem in horizontal well production.A lot of water will make the horizontal well oil production decreased suddenly,water content increased,oil production decreased. After water plugging was carried out in the horizontal wells,the water content decreased sinerely,the oil production rate is obviously improved,the effect is obvious.
