In order to improve the ROP of lower section under 3000m depth in Yi1 well of Mongolia, hydro-efflux hammer rotary-percussion drilling technology was used.According to the characteristics of the formation lithology, the impact power and the frequency were selected by the hammer rig testing to determine the rotary-percussion drilling parameters.The hydro-efflux hammer was used in the section of 3675m to 3817m with the cone bit.With the reasonable hydraulic parame-ters and performance parameters of the hammer, the desired high ROP was achieved.The net drilling time of the hammer was 185h with total footage of 142m;under the conditions of the similar stratum and the bit, the footage of 2 rounds rotary-percussion drilling was 10m more than that of previous 4 rounds rotary drilling, and the ROP was increased by 42%, the rotary-percussion drilling technology became a new technical means for Baiyinchagan area.
