| Abstract: | Both the PDM and the DTH hammer belong to the downhole motor. lt's difficult to compound them. ln this paper, we analyzed the drill parameters matching, its joining way, water power consumption, etc., and researched the compound drill in- detail. Finally, we design two types of compound drill model which are suitable for the scientific drilling , which sed a good foundation for further studying them. |
