介绍了一种取出式改进型偏心楔的侧钻方法、工艺措施及侧钻效果。与传统偏心楔侧钻法比较，具有偏孔速度快、可取出斜面岩心、无专程扩孔工序、不留事故隐患、不影响后续绳索取心钻进、偏心楔可重复使用等优点。解决了某矿区ZK901孔在坚硬岩中侧钻处理烧钻事故的关键技术难题。
介紹瞭一種取齣式改進型偏心楔的側鑽方法、工藝措施及側鑽效果。與傳統偏心楔側鑽法比較，具有偏孔速度快、可取齣斜麵巖心、無專程擴孔工序、不留事故隱患、不影響後續繩索取心鑽進、偏心楔可重複使用等優點。解決瞭某礦區ZK901孔在堅硬巖中側鑽處理燒鑽事故的關鍵技術難題。

The paper introduces an improved retrievable eccentric wedge about its sidetracking method, technological meas-ures and the efficiency.Compared with the traditional one, this eccentric wedge has the advantages of fast sidetracking, in-clined coring, no accident threat, no influence on subsequent wire-line core drilling, no specific reaming process and reuse of the eccentric wedge, by which the technical difficulties of bit burning were solved with sidetracking for ZK901 in hard rocks.
