摘　　要：山074-61井位于长庆南梁西区油田,该区块地层存在裂缝发育,失返性井漏时有发生。该井在钻至华池组地层时发生失返性漏失,在采取3次桥塞挤封堵漏和2次填充堵漏后,最终堵漏成功。介绍了堵漏过程并对其进行了分析。该井堵漏的成功对于今后在该区域施工井的井漏处理有一定的借鉴作用。The well Shan074-61 is located in Chanqing oil field with well-developed fractures,where mud losses withno return are encountered frequently.In this well,while drilling to formation of Huachi group,a no return mud loss isencountered,after three times of squeezing bridging and two times of packing operations,the severe mud loss is controlledsuccessfully.In this paper,the process of the sealing operation is introduced,and this operation can be a successful sampleto other wells.
