| Abstract: | Yi 185 well was an important appraisal well, and it was located on the fifth fault block of Ji Yang Downwarp in Bohai Bay Basin. The total depth was 4700m. The length of open well was 3200m and abtra- gung cave ftequently occurred because of crack in the second interval. Bottomhole temperature was high- er than 180~C and the drilling fluid density was heavy, so exploratory drilling difficulty was great. After impervious and polymer drilling fluid and polyamine and anti-high temperature drilling fluid were applicat- ed and the corresponding maintenance and handling technics was asisted, the well was finished successful- ly. Down-hole troublesome condition didn＇t occurred during the course of drilling. At last, the success ex- ploration provided technology support to others well in the oilfield. |
