Application of PDC Bit in Shaqiu-3 Well Area in Shanan Oilfield

Combining with downhole service's practical situation, taking the field application of drilling by PDC bit for example, the PDC bit's performance and application in oilfield are discussed one by one. And a comparison of drillability is made between the PDC bit and SHIIR bit in the same section; the PDC bit's universal experience and law of drilling by using PDC bit in situ are obtained.
