Abstract：Study and summarize the technology and method of well completion,Packer use,pumping and other key links,sum up experience and lessons,accumulate multi-layered precision pumping drilling technology and experience.Through the analysis of the theoretical foundation of drilling design,engineering geological foundation of drilling,typical well bore structure of drilling,and the basic process of multi-layer pumping drilling,this paper studies and summarizes the multi-layered fine pumping construction technology.According to the drillability of rock in drilling construction,using reasonable combination of drilling tools to improve drilling efficiency,using effective means to prevent hole deviation,reasonable selection of drilling pressure,rotating speed and pump volume in drilling,drilling hole after drilling,the benefit is improved and the construction risk is reduced by timely hydrogeological logging and casing fixing,water sealing and water pumping in the non-pumping section.
