为提高塔河油田超深井小井眼钴进速度,缩短钻井周期,设计并试制了一种具有金属密封的TDR1-127减速涡轮钻具,并在TH12509小井眼井中进行了试验,试验井段的钻速与同井相邻地层转盘钻井方式的钻速相比提高了80%以上,与邻井转盘钻井方式钻进相同地层的钻速相比提高了55%以上.理论与试验结果表明,TDR1-127减速涡轮钻具结构设计合理,工作寿命长,能够满足塔河油田超深井小井眼复合钻井需要,可进一步推广应用.

In order to increase the slim hole drilling speed at ultra-deep wells in Tahe Oilfield ultra-deep, the reduction turbodrill 127 which has metal surface sealed structure is designed and successfully trial-produced. It has been tested through composite drilling in TH 12509 slim-hole well. As a result the average drilling speed of the tested hole section increases more than 80% as compared to that of the same well in adjacent strata and more than 55% comparing with that of the adjacent well in the same strata in condition of turntable drilling. It is indicated that the structure of reduction turbodrill TDR1-127 is reasonable, which has long service life and meets the reqire-ments of slim-hole composite drilling at ultra-deep wells in Tahe Oilfield.
