| Abstract: | There are 2 designed boreholes in the complex formation in Huangcuoping iron mining area of Anxi,Fujian.Hole 01 drilling encountered leakage sections,several control methods were taken for the completion but drilling efficiency was seriously affected.The experience and lessons were summed up for the Hole 02,improvement was made on the wall protection and leakage control with good result.The paper introduced the process of wall protection and leakage control in the 2 holes,summed up the leakage control measures and the experience of selecting control method in serious broken and leakage formation. |
