| Abstract: | The completed well depth of Yun’an 7-1 well was 5810m.Its sidetracking point was the deepest of the directional well in Sichuan area. And it was one of the recent deep directional wells in Chuandong area whose hole conditions were the most complicated.This paper mainly discussed the designation and operation of directional sidetracking and well track control.Meanwhile,it discussed the major technological measures to prevent the occurance of downhole troubles in deep directional wells,such as lost circulation,well blowout,well slough and drillpipe sticking. |
