| 摘 要： | 河南桐柏吴城碱矿采卤生产井堵漏问题一直困扰着该地区采卤井钻井速度,多年来未取得突破性进展。经过在SP08井现场进行水泥注浆堵漏试验,得出该地层漏失特性为遇水可溶的裂缝性漏失。根据这个特性,结合室内试验,从堵漏材料选择、工艺两方面较为系统地总结出该地区堵漏技术,制定出以高失水材料为主,配合桥堵材料综合技术措施及承压工艺方法。为今后该矿区快速、高效堵漏提供了有效的技术支持。

| Abstract: | The effect of leakage stoppage has been affected the drilling speed of brine extraction well of alkali mine in Tongbai of Henan.By the leakage stoppage test with cement grouting in well SP08,it was found that the leakage characteristic of this stratum is fractured loss.Based on this characteristic and according to the laboratory test,a leakage stoppage technology for this region was systematically summed up in choice of leakage stoppage material and technology.A comprehensive technical measure and pressure sealing method mainly with high water loss material matching bridging blockage material was made to provide technical support in this mining area. |

| Keywords: | water soluble fractured formation loss saturated saltwater slurry high water loss pressure sealing |
