| Abstract: | In order to meet the requirement of faster penetration, the PDC bit was used widely in drilling operation to improve drilling speed, reduce make a trip, and avoid lost cone etc. accident. During using PDC bit, there was bit balling phenomenon. Based on analyzing the cause of balling up, through improving the performance of drilling fluid, and changing drilling parameters, the paper put forward the technical measures of prevention PDC bit balling. They help to solve the problem of PDC bit balling. |
