水平井技术在正韵律厚油层次生底水油藏挖潜中的应用

水平井技术是挖潜特高含水期正韵律厚油层顶部剩余油富集区最有效的方法。羊二庄油田经过30多年的开发，已进入“双高”开发后期阶段，由于受储层非均质性和长期注水冲刷的影响，油层水淹严重，剩余油分布零散，挖潜难度大。水平井技术在羊二庄正韵律厚油层次生底水油藏的成功应用，为同类型油藏剩余油富集区水平井挖潜提供了借鉴。

Application of Horizontal Well Tech in Digging Potential to Oil Reservoir with Hypo-Produce Bottom Water and Positive Gradus Thick Oil Layer

Horizontal well tech is an effective way to dig potential of residual oil enrichment part above normal rhythm thick oil layer with high water content. Through 30 years of development for Yang'erzhuang oilfield, it already turns into double high later exploited period. Because of the influence from heterogeneous nature and washing out of water for a long time, the oil layer is water flooded seriously and residual oil distribution is scattered that is difficult to dig potential. The successful application of horizontal well tech in Yang erzhuang oilfield provides a reference for digging potential to the same type of reservoir.
