甘肃文县阳山矿区复杂地层用冲洗液研究

Study on Washing Fluids for Complex Formation in Yangshan Mining Area of Gansu

摘要:

介绍了甘肃文县阳山矿区泡沫冲洗液和HJ-YS系列冲洗液的研制与应用。以42线ZK706孔和51线ZK3002、ZK3016、ZKN3084、ZK0204钻孔为例，首先介绍了泡沫冲洗液在孔壁失稳地层的应用效果；其次介绍了低固相植物胶HJ-YS系列冲洗液对破碎强烈、多溶洞、易漏失、水敏性强、采心困难的复杂地层所具有的良好的润滑减阻和护壁堵漏效果。

Abstract:

The paper discussed the development and application of foam washing fluid and HJ-YS series washing fluid for Yangshan mining area of Gansu. With the cases of ZK706 in 42 exploration line, and ZK3002, ZK3016, ZKN3084 and ZK0204 in 51 exploration line, the application effect of foam washing fluid to hole wall instability is firstly introduced; then the application effect of HJ-YS series washing fluid are introduced. This low solid plant gum has lubricating resistance-reducing and wall protection effects in serious broken, multi-karst cave, leakage, high water-sensitivity and difficult coring formations.
