| Abstract: | In order to complete workover technology of special structure well in the slim hole side- tracking directional well, improve operating efficiency and fishing success ratio, fishing technology in the slim hole sidetracking directional well was researched, fishing difficult points in slim hole sidetracking was analyzed, pipe string force was studied, combination structure of pipe string, milling and fishing tools were improved, and reasonable parameters of milling operation were determined, such as WOB of 30 ~ 35 kN, displacement of 400 L/min, bit penetration of 90-120 r/rain. Field application showed that average milling speed was 0.42 m/h, fishing success ratio was up to 93.9 %. |
