| 摘 要： | 为了提高内蒙古意1井3000 m以深下部井段机械钻速，采用了射流冲击器旋冲钻井提速技术。根据地层岩性特点，通过冲击器台架性能测试，优选出了冲击器的冲击功及冲击频率，确定了旋冲钻井参数。射流冲击器配合牙轮钻头应用井段为3675～3817 m，通过合理确定水力参数及冲击器的性能参数，取得了预期的提速效果，达到了提速增效的目的。冲击器纯钻共计185 h，总进尺142 m，采用旋冲钻井技术，在相同地层及钻头条件下，旋冲钻井2趟钻进进尺较以前转盘钻进4趟钻进进尺多10 m，提高机械钻速达42％，为白音查干区块钻井提供了一项新的技术手段。

| Abstract: | 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. |
