| Abstract: | There are lots of high and steep structures in east Sichuan with vast exploration prospect.But the complicated geologic features of those high and steepstructures will bring much trouble to drilling engineering,especially making itdifficult to drill to narrow target areas,for which "fanning the bottom" drilling technology is usually used to ensure wellbore quality thus severely influencing the improvement of penetration rates and drilling benefits.Outstanding technical economical benefits have been obtained when drilling to targets using formation natural deflecting laws and offsetting well locations.By analyzing geologic structural features and drilling geologic features of high-steep structures,natural deflecting laws of high-steep structure in east Sichuan are illustrated in this paper.Four key technical points of targetting technology are pointed out. |
