摘要:
在海上进行工程地质钻探作业时,对砂粒、松散岩、风化岩等地层需采用泥浆护壁,采用淡水配置泥浆才能达到最佳效果。创建一种海水造浆双流程模型,一级流程装置输出的初纯水满足高性能泥浆用水标准;二级流程去除水中残存的盐类,制成适于饮用的超纯水。设计的实用海水造浆装置,包括海水预处理、反渗透装置、EDI分离器及维护控制系统等,从而突破了海上勘探受制于平台空间、载荷、淡水成本等因素制约,有效地降低了勘探成本。

Abstract:
For engineering geological drilling operations at sea, mud protection is necessary in sand, loose rock and weath-ered rock stratum, and the best effects can only be achieved by using the mud prepared with fresh water.By establishing a two-process model of mud making with seawater, primary pure water produced by the first-stage process device can meet the water standards for high-performance mud;ultrapure water suitable for drinking is output by the second-stage process with the residual salts being removed.The designed seawater mud making device, including seawater pretreatment and reverse osmosis devices, EDI separator and maintenance control system, breaks through the the restriction of platform space, load, fresh water cost and other factors in the offshore exploration, the exploration cost is effectively reduced.
