2015年开年之际,中国石化西南石油工程公司临盘钻井分公司引进的脉冲喷嘴在盘40一斜207侧井首试成功,通过在该井分段试验和对比,使用该新型工具钻速提高达92.55%,提速效果显著。脉冲喷嘴是将钻井过程中钻具内钻井液通过特殊结构设计的喷嘴后转变成脉冲射流,从而改变井底常规钻井液流场压力状况,进而提高机械钻速的一种新工具。在盘40—斜207侧井钻井中,使用该工具在井段2 572~2 955 m、3 089~3 300 m分段试验,
In the opening year of 2015, the pulse nozzle introduced by Linpan Branch of Sinopec Southwest Petroleum Engineering Co., Ltd. was successfully tested on the first side of the well of plate No.40-207. Through the well test and comparison in this well, the new tool was used to drill Increase up to 92.55%, speed up the effect is remarkable. The pulse jet is a new tool to change the pressure condition of the normal drilling fluid flow field and then increase the ROP by changing the drilling fluid in the drilling tool through a specially designed nozzle into a pulsed jet. In the side of well 40-inclined borehole 207 drilling, the tool was used in the well section of 2 572 ~ 2 955 m, 3 089 ~ 3 300 m section test,
