泥浆不落地技术在DY-4井中的应用

Application of drilling mud non-landing technology in Well DY-4

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。

Abstract:

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.
