杭锦旗区块是鄂尔多斯盆地近年来的重点开发区域,位于鄂尔多斯盆地北部,横跨伊盟隆起、伊陕斜坡和天环向斜三个一级构造单元。该区块平面构造复杂、断裂发育、易漏层纵向分布。尤其刘家沟组发育高角度天然微裂缝及水平层理缝,且横向连通,渗漏情况严重。文章简要论述了杭锦旗区块防漏堵漏技术,尤其是对速封堵漏、雷特堵漏、KPD堵漏等堵漏方法在现场的应用情况进行了深刻剖析,旨在为杭锦旗区块提供更好的防漏堵漏技术。
The Hangjinqi Block is a key development area in the Ordos Basin in recent years. It is located in the north of Ordos Basin and covers three first-grade tectonic units, including the Yimeng Uplift, the Yi-Shan Slope and the Tianhuan syncline. The block plane structure is complex, fracture development, easy vertical distribution of leakage layer. In particular, the Liujiagou Formation developed high-angle natural microcracks and horizontal bedding fractures with lateral connectivity and serious leakage. The article briefly discusses the block leakage blocking technology of Hangjinqi block, especially the application of plugging methods such as speed sealing and plugging, Leite plugging, KPD plugging and so on in the field, Block provides better leak-proof plugging technology.
