摘　　要：义189是一口重点探井,本井技套较浅,三开裸眼井段长,地层压力上高下低,沙四段稳定性差,掉块严重,夹盐膏层、含H2S,地层裂缝发育,累计漏失500m3泥浆。总结了该井所采取的钻井液技术措施。Yi189 is a key exploration well, has a short the intermediate casing, long uncorrected well with third opening, high pressure in upper formation and lower pressure on the bottom formation. In Sha4 section it has a poor stability, dropping blocks seriously, has salt gypsum layer and H2S, developed formation fractures, cumulative leakage 500m3 mud. The paper summarized drilling fluid tech- nical measures for the well.
