| Abstract:As an exploration well, Xuanye Well 1 was designed 2570m in vertical depth for shale gas resource potential evaluation. The construction was mainly drilling in the Mesozoic-Paleozoic formation with dense lithology, drillability extreme of 8~10 and formation tip about 45. Based on the analysis on the technology and the mechanism of deviation control with tower-type drilling tool, eccentric drilling tool, compound drilling and vertical well drilling; the paper introduced the experimental application of all kinds of deviation control technologies in Xuanye Well 1, and the application effects of all kinds of deviation control technologies were evaluated. |
