摘　　要：通过对水基和油基泥浆不落地系统的研究分析,总结了2种不落地系统的处理流程与核心技术,结合DY-4井的实际情况,设计了一套基于普通固控系统的泥浆不落地处理方案,并完成了方案的实施。改造后的不落地系统,由于舍去了泥浆池和沉淀池,整个泥浆循环、净化、回收过程均未发生泥浆外渗,十分环保。Through the research and analysis of the water-based and oil-based mud non-landing systems,the treatment process and core technology of two non-landing systems are summarized.In light of the actual situation of Well DY 4,a mud non-landing treatment plan based on the ordinary solid control systems has been designed,and implemented.Through modification,the non-landing system eliminated the mud pit and the settlement tank,avoiding any leakage from the whole mud circulation process of mud circulation,purification and recycling;hence,very environmentally friendly.
