Jilh, sudair and Khuff are encountered in the third spud in section of ATN block in Saudi Aramco. The corresponding well depth is 3040-4150m, dominated by dolomite, limestone and carbonate. The formation is hard and abrasive. The shale in the upper section is unstable and the falling block is serious, resulting in the increase of mud weight, which makes drilling more difficult. There is no effect by using down hole power drilling tools such as mortor. Field test shows that the Φ228Hydra-efflux hammer can effectively solve the low ROP problem in hard formation machinery. Based on the quantitative analysis of the rock compressive strength of the above formation, according to the relationship between the performance parameters of the hydraulic jet impactor and the rock drilling resistance parameters, combined with the application well design, the scheme of speed-up of rotary percussion drilling with the Φ228 Hydra-efflux hammer is formulated, and the rotary percussion drilling parameters are optimized. On this basis, the BHA and matching bit are further optimized, and the impact resistance and aggressiveness of matching bit are analyzed. It has been applied in ATN-1123 well. The application results show that the ROP increase effectively by using Φ228 Hydra-efflux hammer, which is 47% higher than the average ROP of adjacent wells. This successful application provides an effective technical means for increasing ROP drilling in the hard formation of the block.
