冻胶在塔河九区碎屑岩油藏水平井堵水中的应用

塔河油田九区三叠系底水砂岩油藏以水平井开发为主。由于底水能量充足，非均质性严重，开发过程中易沿高渗段脊进形成水侵优势通道，导致油井部分水淹，含水迅速上升。采用具有强封堵性和强油水选择性的冻胶封堵出水孔道，降低含水，堵剂即使进入油水同出通道，也能因其强油水选择性实现堵水而少堵油，该技术在现场实践中取得了较好的效果。

Gels to plug water in horizontal wells in clastic rock reservoir in district 9 of Tahe Oil Field

Horizontal wells, as one of the most efficient ways, are applied to develop the Triassic bottom water sandstone reservoir in district 9 of the Tahe Oilfield. Because of sufficient bottom water energy and serious heterogeneity, water coning can be formed along hypertonic paragraph, resulting in quick increasing of water content. Gels with strong plugging capacity and strong oil-water selectivity are used to block water channels. Water is blocked much more than oil even though gels enter into oil-water passage due to strong oil-water selectivity. This technology applies well in practice testing.
